Bosch C_CAN/D_CAN controller Device Tree Bindings
-------------------------------------------------
Required properties:
- compatible : Should be "bosch,c_can" for C_CAN controllers and
"bosch,d_can" for D_CAN controllers.
Can be "ti,dra7-d_can", "ti,am3352-d_can" or
"ti,am4372-d_can".
- reg : physical base address and size of the C_CAN/D_CAN
registers map
- interrupts : property with a value describing the interrupt
number
The following are mandatory properties for DRA7x, AM33xx and AM43xx SoCs only:
- ti,hwmods : Must be "d_can<n>" or "c_can<n>", n being the
instance number
The following are mandatory properties for Keystone 2 66AK2G SoCs only:
- power-domains : Should contain a phandle to a PM domain provider node
and an args specifier containing the DCAN device id
value. This property is as per the binding,
Documentation/devicetree/bindings/soc/ti/sci-pm-domain.yaml
- clocks : CAN functional clock phandle. This property is as per the
binding,
Documentation/devicetree/bindings/clock/ti,sci-clk.yaml
Optional properties:
- syscon-raminit : Handle to system control region that contains the
RAMINIT register, register offset to the RAMINIT
register and the CAN instance number (0 offset).
Note: "ti,hwmods" field is used to fetch the base address and irq
resources from TI, omap hwmod data base during device registration.
Future plan is to migrate hwmod data base contents into device tree
blob so that, all the required data will be used from device tree dts
file.
Example:
Step1: SoC common .dtsi file
dcan1: d_can@481d0000 {
compatible = "bosch,d_can";
reg = <0x481d0000 0x2000>;
interrupts = <55>;
interrupt-parent = <&intc>;
status = "disabled";
};
(or)
dcan1: d_can@481d0000 {
compatible = "bosch,d_can";
ti,hwmods = "d_can1";
reg = <0x481d0000 0x2000>;
interrupts = <55>;
interrupt-parent = <&intc>;
status = "disabled";
};

* Freescale Fast Ethernet Controller (FEC)
Required properties:
- compatible : Should be "fsl,<soc>-fec"
- reg : Address and length of the register set for the device
- interrupts : Should contain fec interrupt
- phy-mode : See ethernet.txt file in the same directory
Optional properties:
- phy-supply : regulator that powers the Ethernet PHY.
- phy-handle : phandle to the PHY device connected to this device.
- fixed-link : Assume a fixed link. See fixed-link.txt in the same directory.
Use instead of phy-handle.
- fsl,num-tx-queues : The property is valid for enet-avb IP, which supports
hw multi queues. Should specify the tx queue number, otherwise set tx queue
number to 1.
- fsl,num-rx-queues : The property is valid for enet-avb IP, which supports
hw multi queues. Should specify the rx queue number, otherwise set rx queue
number to 1.
- fsl,magic-packet : If present, indicates that the hardware supports waking
up via magic packet.

the hardware workaround for ERR006687 applied and does not need a software
workaround.
- fsl,stop-mode: register bits of stop mode control, the format is
<&gpr req_gpr req_bit>.
gpr is the phandle to general purpose register node.
req_gpr is the gpr register offset for ENET stop request.
req_bit is the gpr bit offset for ENET stop request.
-interrupt-names: names of the interrupts listed in interrupts property in
the same order. The defaults if not specified are
__Number of interrupts__ __Default__
1 "int0"
2 "int0", "pps"
3 "int0", "int1", "int2"
4 "int0", "int1", "int2", "pps"
The order may be changed as long as they correspond to the interrupts
property. Currently, only i.mx7 uses "int1" and "int2". They correspond to
tx/rx queues 1 and 2. "int0" will be used for queue 0 and ENET_MII interrupts.
For imx6sx, "int0" handles all 3 queues and ENET_MII. "pps" is for the pulse
per second interrupt associated with 1588 precision time protocol(PTP).
Optional subnodes:
- mdio : specifies the mdio bus in the FEC, used as a container for phy nodes
according to phy.txt in the same directory
Deprecated optional properties:
To avoid these, create a phy node according to phy.txt in the same
directory, and point the fec's "phy-handle" property to it. Then use
the phy's reset binding, again described by phy.txt.
- phy-reset-gpios : Should specify the gpio for phy reset

DPAA2 Switch driver
===================
:Copyright: |copy| 2021 NXP
The DPAA2 Switch driver probes on the Datapath Switch (DPSW) object which can
be instantiated on the following DPAA2 SoCs and their variants: LS2088A and
LX2160A.
The driver uses the switch device driver model and exposes each switch port as
a network interface, which can be included in a bridge or used as a standalone
interface. Traffic switched between ports is offloaded into the hardware.
The DPSW can have ports connected to DPNIs or to DPMACs for external access.

Creating an Ethernet Switch
===========================
The dpaa2-switch driver probes on DPSW devices found on the fsl-mc bus. These
devices can be either created statically through the boot time configuration
file - DataPath Layout (DPL) - or at runtime using the DPAA2 object APIs
(incorporated already into the restool userspace tool).
At the moment, the dpaa2-switch driver imposes the following restrictions on
the DPSW object that it will probe:
* The minimum number of FDBs should be at least equal to the number of switch
interfaces. This is necessary so that separation of switch ports can be
done, ie when not under a bridge, each switch port will have its own FDB.
::
fsl_dpaa2_switch dpsw.0: The number of FDBs is lower than the number of ports, cannot probe
* Both the broadcast and flooding configuration should be per FDB. This
enables the driver to restrict the broadcast and flooding domains of each
FDB depending on the switch ports that are sharing it (aka are under the

Besides the configuration of the actual DPSW object, the dpaa2-switch driver
will need the following DPAA2 objects:
* 1 DPMCP - A Management Command Portal object is needed for any interraction
with the MC firmware.
* 1 DPBP - A Buffer Pool is used for seeding buffers intended for the Rx path
on the control interface.
* Access to at least one DPIO object (Software Portal) is needed for any
enqueue/dequeue operation to be performed on the control interface queues.
The DPIO object will be shared, no need for a private one.
Switching features
==================
The driver supports the configuration of L2 forwarding rules in hardware for
port bridging as well as standalone usage of the independent switch interfaces.
The hardware is not configurable with respect to VLAN awareness, thus any DPAA2
switch port should be used only in usecases with a VLAN aware bridge::
$ ip link add dev br0 type bridge vlan_filtering 1
$ ip link add dev br1 type bridge
$ ip link set dev ethX master br1
Error: fsl_dpaa2_switch: Cannot join a VLAN-unaware bridge
Topology and loop detection through STP is supported when ``stp_state 1`` is
used at bridge create ::
$ ip link add dev br0 type bridge vlan_filtering 1 stp_state 1
L2 FDB manipulation (add/delete/dump) is supported.
HW FDB learning can be configured on each switch port independently through
bridge commands. When the HW learning is disabled, a fast age procedure will be
run and any previously learnt addresses will be removed.
::
$ bridge link set dev ethX learning off
$ bridge link set dev ethX learning on
Restricting the unknown unicast and multicast flooding domain is supported, but
not independently of each other::
$ ip link set dev ethX type bridge_slave flood off mcast_flood off
$ ip link set dev ethX type bridge_slave flood off mcast_flood on
Error: fsl_dpaa2_switch: Cannot configure multicast flooding independently of unicast.
Broadcast flooding on a switch port can be disabled/enabled through the brport sysfs::
$ echo 0 > /sys/bus/fsl-mc/devices/dpsw.Y/net/ethX/brport/broadcast_flood
Offloads
========
Routing actions (redirect, trap, drop)
--------------------------------------
The DPAA2 switch is able to offload flow-based redirection of packets making
use of ACL tables. Shared filter blocks are supported by sharing a single ACL
table between multiple ports.
The following flow keys are supported:
* Ethernet: dst_mac/src_mac
* IPv4: dst_ip/src_ip/ip_proto/tos
* VLAN: vlan_id/vlan_prio/vlan_tpid/vlan_dei
* L4: dst_port/src_port
Also, the matchall filter can be used to redirect the entire traffic received
on a port.
As per flow actions, the following are supported:
* drop
* mirred egress redirect
* trap
Each ACL entry (filter) can be setup with only one of the listed
actions.
Example 1: send frames received on eth4 with a SA of 00:01:02:03:04:05 to the
CPU::
$ tc qdisc add dev eth4 clsact
$ tc filter add dev eth4 ingress flower src_mac 00:01:02:03:04:05 skip_sw action trap
Example 2: drop frames received on eth4 with VID 100 and PCP of 3::
$ tc filter add dev eth4 ingress protocol 802.1q flower skip_sw vlan_id 100 vlan_prio 3 action drop
Example 3: redirect all frames received on eth4 to eth1::
$ tc filter add dev eth4 ingress matchall action mirred egress redirect dev eth1
Example 4: Use a single shared filter block on both eth5 and eth6::
$ tc qdisc add dev eth5 ingress_block 1 clsact
$ tc qdisc add dev eth6 ingress_block 1 clsact
$ tc filter add block 1 ingress flower dst_mac 00:01:02:03:04:04 skip_sw \
action trap
$ tc filter add block 1 ingress protocol ipv4 flower src_ip 192.168.1.1 skip_sw \
action mirred egress redirect dev eth3
Mirroring
~~~~~~~~~
The DPAA2 switch supports only per port mirroring and per VLAN mirroring.
Adding mirroring filters in shared blocks is also supported.
When using the tc-flower classifier with the 802.1q protocol, only the
''vlan_id'' key will be accepted. Mirroring based on any other fields from the
802.1q protocol will be rejected::
$ tc qdisc add dev eth8 ingress_block 1 clsact
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_prio 3 action mirred egress mirror dev eth6
Error: fsl_dpaa2_switch: Only matching on VLAN ID supported.
We have an error talking to the kernel
If a mirroring VLAN filter is requested on a port, the VLAN must to be
installed on the switch port in question either using ''bridge'' or by creating
a VLAN upper device if the switch port is used as a standalone interface::
$ tc qdisc add dev eth8 ingress_block 1 clsact
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_id 200 action mirred egress mirror dev eth6
Error: VLAN must be installed on the switch port.
We have an error talking to the kernel
$ bridge vlan add vid 200 dev eth8
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_id 200 action mirred egress mirror dev eth6
$ ip link add link eth8 name eth8.200 type vlan id 200
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_id 200 action mirred egress mirror dev eth6
Also, it should be noted that the mirrored traffic will be subject to the same
egress restrictions as any other traffic. This means that when a mirrored
packet will reach the mirror port, if the VLAN found in the packet is not
installed on the port it will get dropped.
The DPAA2 switch supports only a single mirroring destination, thus multiple
mirror rules can be installed but their ''to'' port has to be the same::
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_id 200 action mirred egress mirror dev eth6
$ tc filter add block 1 ingress protocol 802.1q flower skip_sw vlan_id 100 action mirred egress mirror dev eth7
Error: fsl_dpaa2_switch: Multiple mirror ports not supported.

Benefits:
- Can terminate untagged traffic over switch net
devices even when enslaved to a bridge with
vlan_filtering=1.
- Can terminate VLAN-tagged traffic over switch net
devices even when enslaved to a bridge with
vlan_filtering=1, with some constraints (no more than
7 non-pvid VLANs per user port).
- Can do QoS based on VLAN PCP and VLAN membership
admission control for autonomously forwarded frames
(regardless of whether they can be terminated on the
CPU or not).
Drawbacks:
- User cannot use VLANs in range 1024-3071. If the
switch receives frames with such VIDs, it will
misinterpret them as DSA tags.
- Switch uses Shared VLAN Learning (FDB lookup uses
only DMAC as key).
- When VLANs span cross-chip topologies, the total
number of permitted VLANs may be less than 7 per
port, due to a maximum number of 32 VLAN retagging
rules per switch.

Note that this assumes a DSA-unaware master driver, which is the norm.
Hardware manufacturers are strongly discouraged to do this, but some tagging
protocols might not provide source port information on RX for all packets, but
e.g. only for control traffic (link-local PDUs). In this case, by implementing
the ``filter`` method of ``struct dsa_device_ops``, the tagger might select
which packets are to be redirected on RX towards the virtual DSA user network
interfaces, and which are to be left in the DSA master's RX data path.
It might also happen (although silicon vendors are strongly discouraged to
produce hardware like this) that a tagging protocol splits the switch-specific
information into a header portion and a tail portion, therefore not falling
cleanly into any of the above 3 categories. DSA does not support this
configuration.

Traffic support
===============
The switches do not have hardware support for DSA tags, except for "slow
protocols" for switch control as STP and PTP. For these, the switches have two
programmable filters for link-local destination MACs.
These are used to trap BPDUs and PTP traffic to the master netdevice, and are
further used to support STP and 1588 ordinary clock/boundary clock
functionality. For frames trapped to the CPU, source port and switch ID
information is encoded by the hardware into the frames.
But by leveraging ``CONFIG_NET_DSA_TAG_8021Q`` (a software-defined DSA tagging
format based on VLANs), general-purpose traffic termination through the network
stack can be supported under certain circumstances.
Depending on VLAN awareness state, the following operating modes are possible
with the switch:
- Mode 1 (VLAN-unaware): a port is in this mode when it is used as a standalone
net device, or when it is enslaved to a bridge with ``vlan_filtering=0``.
- Mode 2 (fully VLAN-aware): a port is in this mode when it is enslaved to a
bridge with ``vlan_filtering=1``. Access to the entire VLAN range is given to
the user through ``bridge vlan`` commands, but general-purpose (anything
other than STP, PTP etc) traffic termination is not possible through the
switch net devices. The other packets can be still by user space processed
through the DSA master interface (similar to ``DSA_TAG_PROTO_NONE``).
- Mode 3 (best-effort VLAN-aware): a port is in this mode when enslaved to a
bridge with ``vlan_filtering=1``, and the devlink property of its parent
switch named ``best_effort_vlan_filtering`` is set to ``true``. When
configured like this, the range of usable VIDs is reduced (0 to 1023 and 3072
to 4094), so is the number of usable VIDs (maximum of 7 non-pvid VLANs per
port*), and shared VLAN learning is performed (FDB lookup is done only by
DMAC, not also by VID).
To summarize, in each mode, the following types of traffic are supported over
the switch net devices:
+-------------+-----------+--------------+------------+
| | Mode 1 | Mode 2 | Mode 3 |
+=============+===========+==============+============+
| Regular | Yes | No | Yes |

\* "maximum of 7 non-pvid VLANs per port": Decoding VLAN-tagged packets on the
CPU in mode 3 is possible through VLAN retagging of packets that go from the
switch to the CPU. In cross-chip topologies, the port that goes to the CPU
might also go to other switches. In that case, those other switches will see
only a retagged packet (which only has meaning for the CPU). So if they are
interested in this VLAN, they need to apply retagging in the reverse direction,
to recover the original value from it. This consumes extra hardware resources
for this switch. There is a maximum of 32 entries in the Retagging Table of
each switch device.
As an example, consider this cross-chip topology::

To reach the CPU, SJA1105 switch 1 (spi/spi2.1) uses the same port as is uses
to reach SJA1105 switch 2 (spi/spi2.2), which would be port 4 (not drawn).

SJA1105 switch 1 consumes 1 retagging entry for each VLAN on each user port
towards the CPU. It also consumes 1 retagging entry for each non-pvid VLAN that
it is also interested in, which is configured on any port of any neighbor
switch.
In this case, SJA1105 switch 1 consumes a total of 11 retagging entries, as
follows:
- 8 retagging entries for VLANs 1 and 100 installed on its user ports
(``sw1p0`` - ``sw1p3``)
- 3 retagging entries for VLAN 100 installed on the user ports of SJA1105
switch 2 (``sw2p0`` - ``sw2p2``), because it also has ports that are
interested in it. The VLAN 1 is a pvid on SJA1105 switch 2 and does not need
reverse retagging.
SJA1105 switch 2 also consumes 11 retagging entries, but organized as follows:
- 7 retagging entries for the bridge VLANs on its user ports (``sw2p0`` -
``sw2p3``).
- 4 retagging entries for VLAN 100 installed on the user ports of SJA1105

Segregating the switch ports in multiple bridges is supported (e.g. 2 + 2), but
all bridges should have the same level of VLAN awareness (either both have
``vlan_filtering`` 0, or both 1). Also an inevitable limitation of the fact
that VLAN awareness is global at the switch level is that once a bridge with
``vlan_filtering`` enslaves at least one switch port, the other un-bridged
ports are no longer available for standalone traffic termination.

Topology and loop detection through STP is supported.
L2 FDB manipulation (add/delete/dump) is currently possible for the first
generation devices. Aging time of FDB entries, as well as enabling fully static
management (no address learning and no flooding of unknown traffic) is not yet
configurable in the driver.
A special comment about bridging with other netdevices (illustrated with an
example):
A board has eth0, eth1, swp0@eth1, swp1@eth1, swp2@eth1, swp3@eth1.
The switch ports (swp0-3) are under br0.
It is desired that eth0 is turned into another switched port that communicates
with swp0-3.
If br0 has vlan_filtering 0, then eth0 can simply be added to br0 with the
intended results.
If br0 has vlan_filtering 1, then a new br1 interface needs to be created that
enslaves eth0 and eth1 (the DSA master of the switch ports). This is because in
this mode, the switch ports beneath br0 are not capable of regular traffic, and
are only used as a conduit for switchdev operations.

Management Component Transport Protocol (MCTP)
==============================================
net/mctp/ contains protocol support for MCTP, as defined by DMTF standard
DSP0236. Physical interface drivers ("bindings" in the specification) are
provided in drivers/net/mctp/.
The core code provides a socket-based interface to send and receive MCTP
messages, through an AF_MCTP, SOCK_DGRAM socket.
Structure: interfaces & networks
================================
The kernel models the local MCTP topology through two items: interfaces and
networks.
An interface (or "link") is an instance of an MCTP physical transport binding
(as defined by DSP0236, section 3.2.47), likely connected to a specific hardware
device. This is represented as a ``struct netdevice``.
A network defines a unique address space for MCTP endpoints by endpoint-ID
(described by DSP0236, section 3.2.31). A network has a user-visible identifier
to allow references from userspace. Route definitions are specific to one
network.
Interfaces are associated with one network. A network may be associated with one
or more interfaces.
If multiple networks are present, each may contain endpoint IDs (EIDs) that are
also present on other networks.
Sockets API
===========
Protocol definitions
--------------------
MCTP uses ``AF_MCTP`` / ``PF_MCTP`` for the address- and protocol- families.
Since MCTP is message-based, only ``SOCK_DGRAM`` sockets are supported.
.. code-block:: C
int sd = socket(AF_MCTP, SOCK_DGRAM, 0);
The only (current) value for the ``protocol`` argument is 0.
As with all socket address families, source and destination addresses are
specified with a ``sockaddr`` type, with a single-byte endpoint address:
.. code-block:: C
typedef __u8 mctp_eid_t;
struct mctp_addr {
mctp_eid_t s_addr;
};
struct sockaddr_mctp {
unsigned short int smctp_family;
int smctp_network;
struct mctp_addr smctp_addr;
__u8 smctp_type;
__u8 smctp_tag;
};
#define MCTP_NET_ANY 0x0
#define MCTP_ADDR_ANY 0xff
Syscall behaviour
-----------------
The following sections describe the MCTP-specific behaviours of the standard
socket system calls. These behaviours have been chosen to map closely to the
existing sockets APIs.
``bind()`` : set local socket address
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Sockets that receive incoming request packets will bind to a local address,
using the ``bind()`` syscall.
.. code-block:: C
struct sockaddr_mctp addr;
addr.smctp_family = AF_MCTP;
addr.smctp_network = MCTP_NET_ANY;
addr.smctp_addr.s_addr = MCTP_ADDR_ANY;
addr.smctp_type = MCTP_TYPE_PLDM;
addr.smctp_tag = MCTP_TAG_OWNER;
int rc = bind(sd, (struct sockaddr *)&addr, sizeof(addr));
This establishes the local address of the socket. Incoming MCTP messages that
match the network, address, and message type will be received by this socket.
The reference to 'incoming' is important here; a bound socket will only receive
messages with the TO bit set, to indicate an incoming request message, rather
than a response.
The ``smctp_tag`` value will configure the tags accepted from the remote side of
this socket. Given the above, the only valid value is ``MCTP_TAG_OWNER``, which
will result in remotely "owned" tags being routed to this socket. Since
``MCTP_TAG_OWNER`` is set, the 3 least-significant bits of ``smctp_tag`` are not
used; callers must set them to zero.
A ``smctp_network`` value of ``MCTP_NET_ANY`` will configure the socket to
receive incoming packets from any locally-connected network. A specific network
value will cause the socket to only receive incoming messages from that network.
The ``smctp_addr`` field specifies a local address to bind to. A value of
``MCTP_ADDR_ANY`` configures the socket to receive messages addressed to any
local destination EID.
The ``smctp_type`` field specifies which message types to receive. Only the
lower 7 bits of the type is matched on incoming messages (ie., the
most-significant IC bit is not part of the match). This results in the socket
receiving packets with and without a message integrity check footer.
``sendto()``, ``sendmsg()``, ``send()`` : transmit an MCTP message
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
An MCTP message is transmitted using one of the ``sendto()``, ``sendmsg()`` or
``send()`` syscalls. Using ``sendto()`` as the primary example:
.. code-block:: C
struct sockaddr_mctp addr;
char buf[14];
ssize_t len;
/* set message destination */
addr.smctp_family = AF_MCTP;
addr.smctp_network = 0;
addr.smctp_addr.s_addr = 8;
addr.smctp_tag = MCTP_TAG_OWNER;
addr.smctp_type = MCTP_TYPE_ECHO;
/* arbitrary message to send, with message-type header */
buf[0] = MCTP_TYPE_ECHO;
memcpy(buf + 1, "hello, world!", sizeof(buf) - 1);
len = sendto(sd, buf, sizeof(buf), 0,
(struct sockaddr_mctp *)&addr, sizeof(addr));
The network and address fields of ``addr`` define the remote address to send to.
If ``smctp_tag`` has the ``MCTP_TAG_OWNER``, the kernel will ignore any bits set
in ``MCTP_TAG_VALUE``, and generate a tag value suitable for the destination
EID. If ``MCTP_TAG_OWNER`` is not set, the message will be sent with the tag
value as specified. If a tag value cannot be allocated, the system call will
report an errno of ``EAGAIN``.
The application must provide the message type byte as the first byte of the
message buffer passed to ``sendto()``. If a message integrity check is to be
included in the transmitted message, it must also be provided in the message
buffer, and the most-significant bit of the message type byte must be 1.
The ``sendmsg()`` system call allows a more compact argument interface, and the
message buffer to be specified as a scatter-gather list. At present no ancillary
message types (used for the ``msg_control`` data passed to ``sendmsg()``) are
defined.
Transmitting a message on an unconnected socket with ``MCTP_TAG_OWNER``
specified will cause an allocation of a tag, if no valid tag is already
allocated for that destination. The (destination-eid,tag) tuple acts as an
implicit local socket address, to allow the socket to receive responses to this
outgoing message. If any previous allocation has been performed (to for a
different remote EID), that allocation is lost.
Sockets will only receive responses to requests they have sent (with TO=1) and
may only respond (with TO=0) to requests they have received.
``recvfrom()``, ``recvmsg()``, ``recv()`` : receive an MCTP message
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
An MCTP message can be received by an application using one of the
``recvfrom()``, ``recvmsg()``, or ``recv()`` system calls. Using ``recvfrom()``
as the primary example:
.. code-block:: C
struct sockaddr_mctp addr;
socklen_t addrlen;
char buf[14];
ssize_t len;
addrlen = sizeof(addr);
len = recvfrom(sd, buf, sizeof(buf), 0,
(struct sockaddr_mctp *)&addr, &addrlen);
/* We can expect addr to describe an MCTP address */
assert(addrlen >= sizeof(buf));
assert(addr.smctp_family == AF_MCTP);
printf("received %zd bytes from remote EID %d\n", rc, addr.smctp_addr);
The address argument to ``recvfrom`` and ``recvmsg`` is populated with the
remote address of the incoming message, including tag value (this will be needed
in order to reply to the message).
The first byte of the message buffer will contain the message type byte. If an
integrity check follows the message, it will be included in the received buffer.
The ``recv()`` system call behaves in a similar way, but does not provide a
remote address to the application. Therefore, these are only useful if the
remote address is already known, or the message does not require a reply.
Like the send calls, sockets will only receive responses to requests they have
sent (TO=1) and may only respond (TO=0) to requests they have received.

By design, PTP timestamping with a DSA switch does not need any special

the ``.ndo_do_ioctl`` calls towards the host port, and block attempts to enable
the ``.ndo_eth_ioctl`` calls towards the host port, and block attempts to enable
hardware timestamping on it. This is because the SO_TIMESTAMPING API does not

netfilter rules on the VRF device can be used to limit access to services
running in the default VRF context as well.
Using VRF-aware applications (applications which simultaneously create sockets
outside and inside VRFs) in conjunction with ``net.ipv4.tcp_l3mdev_accept=1``
is possible but may lead to problems in some situations. With that sysctl
value, it is unspecified which listening socket will be selected to handle
connections for VRF traffic; ie. either a socket bound to the VRF or an unbound
socket may be used to accept new connections from a VRF. This somewhat
unexpected behavior can lead to problems if sockets are configured with extra
options (ex. TCP MD5 keys) with the expectation that VRF traffic will
exclusively be handled by sockets bound to VRFs, as would be the case with
``net.ipv4.tcp_l3mdev_accept=0``. Finally and as a reminder, regardless of
which listening socket is selected, established sockets will be created in the
VRF based on the ingress interface, as documented earlier.
