mlxsw: spectrum: Support ieee_setapp, ieee_delapp
The APP TLVs are used for communicating priority-to-protocol ID maps for
a given netdevice. Support the following APP TLVs:
- DSCP (selector 5) to configure priority-to-DSCP code point maps. Use
these maps to configure packet priority on ingress, and DSCP code
point rewrite on egress.
- Default priority (selector 1, PID 0) to configure priority for the
DSCP code points that don't have one assigned by the DSCP selector. In
future this could also be used for assigning default port priority
when a packet arrives without DSCP tagging.
Besides setting up the maps themselves, also configure port trust level
and rewrite bits.
Port trust level determines whether, for a packet arriving through a
certain port, the priority should be determined based on PCP or DSCP
header fields. So far, mlxsw kept the device default of trust-PCP. Now,
as soon as the first DSCP APP TLV is configured, switch to trust-DSCP.
Only when all DSCP APP TLVs are removed, switch back to trust-PCP again.
Note that the default priority APP TLV doesn't impact the trust level
configuration.
Rewrite bits determine whether DSCP and PCP fields of egressing packets
should be updated according to switch priority. When port trust is
switched to DSCP, enable rewrite of DSCP field.

mlxsw: spectrum: Replace vPorts with Port-VLAN
As explained in the cover letter, since the introduction of the bridge
offload in the mlxsw driver, information related to the offloaded bridge
and bridge ports was stored in the individual port struct,
mlxsw_sp_port.
This lead to a bloated struct storing both physical properties of the
port (e.g., autoneg status) as well as logical properties of an upper
bridge port (e.g., learning, mrouter indication). While this might work
well for simple devices, it proved to be hard to extend when stacked
devices were taken into account and more advanced use-cases (e.g., IGMP
snooping) considered.
This patch removes the excess information from the above struct and
instead stores it in more appropriate structs that represent the bridge
port, the bridge itself and a VLAN configured on the bridge port.
The membership of a port in a bridge is denoted using the Port-VLAN
struct, which points to the bridge port and also member in the bridge
VLAN group of the VLAN it represents. This allows us to completely
remove the vPort abstraction and consolidate many of the code paths
relating to VLAN-aware and unaware bridges.
Note that the FID / vFID code is currently duplicated, but this will
soon go away when the common FID core will be introduced.

mlxsw: spectrum_ptp: Add counters for GC events
On Spectrum-1, timestamped PTP packets and the corresponding timestamps need to
be kept in caches until both are available, at which point they are matched up
and packets forwarded as appropriate. However, not all packets will ever see
their timestamp, and not all timestamps will ever see their packet. It is
necessary to dispose of such abandoned entries, so a garbage collector was
introduced in commit 5d23e4159772 ("mlxsw: spectrum: PTP: Garbage-collect
unmatched entries").
If these GC events happen often, it is a sign of a problem. However because this
whole mechanism is taking place behind the scenes, there is no direct way to
determine whether garbage collection took place.
Therefore to fix this, on Spectrum-1 only, expose four artificial ethtool
counters for the GC events: GCd timestamps and packets, in TX and RX directions.

mlxsw: spectrum: Support ieee_setapp, ieee_delapp
The APP TLVs are used for communicating priority-to-protocol ID maps for
a given netdevice. Support the following APP TLVs:
- DSCP (selector 5) to configure priority-to-DSCP code point maps. Use
these maps to configure packet priority on ingress, and DSCP code
point rewrite on egress.
- Default priority (selector 1, PID 0) to configure priority for the
DSCP code points that don't have one assigned by the DSCP selector. In
future this could also be used for assigning default port priority
when a packet arrives without DSCP tagging.
Besides setting up the maps themselves, also configure port trust level
and rewrite bits.
Port trust level determines whether, for a packet arriving through a
certain port, the priority should be determined based on PCP or DSCP
header fields. So far, mlxsw kept the device default of trust-PCP. Now,
as soon as the first DSCP APP TLV is configured, switch to trust-DSCP.
Only when all DSCP APP TLVs are removed, switch back to trust-PCP again.
Note that the default priority APP TLV doesn't impact the trust level
configuration.
Rewrite bits determine whether DSCP and PCP fields of egressing packets
should be updated according to switch priority. When port trust is
switched to DSCP, enable rewrite of DSCP field.

mlxsw: spectrum_ethtool: Introduce ptys_max_speed callback
The SBIB register configures the size of an internal buffer that the
Spectrum ASICs use when mirroring traffic on egress. This size should be
taken into account when validating that the port headroom buffers are not
larger than the chip can handle. Up until now this was not done, which is
incidentally not a problem, because the priority group buffers that mlxsw
auto-configures are small enough that the boundary condition could not be
violated.
When dcbnl_setbuffer is implemented, the user gets control over sizes of PG
buffers, and they might overshoot the headroom capacity. However the size
of the SBIB buffer depends on port speed, which cannot be vetoed. There is
obviously no way to retroactively push back on requests for overlarge PG
buffers, or reject an overlarge MTU, or cancel losslessness of a certain
PG.
Therefore, instead of taking into account the current speed when
calculating SBIB buffer size, take into account the maximum speed that a
port with given Ethernet protocol capabilities can have.
To that end, add a new ethtool callback, ptys_max_speed, which determines
this maximum speed.

mlxsw: spectrum: Track priorities in struct mlxsw_sp_hdroom
The mapping from priorities to buffers determines which buffers should be
configured. Lossiness of these priorities combined with the mapping
determines whether a given buffer should be lossy.
Currently this configuration is stored implicitly in DCB ETS, PFC and
ethtool PAUSE configuration. Keeping it together with the rest of the
headroom configuration and deriving it as needed from PFC / ETS / PAUSE
will make things clearer. To that end, add a field "prios" to struct
mlxsw_sp_hdroom.
Previously, __mlxsw_sp_port_headroom_set() took prio_tc as an argument, and
assumed that the same mapping as we use on the egress should be used on
ingress as well. Instead, track this configuration at each priority, so
that it can be adjusted flexibly.
In the following patches, as dcbnl_setbuffer is implemented, it will need
to store its own mapping, and it will also be sometimes necessary to revert
back to the original ETS mapping. Therefore track two buffer indices: the
one for chip configuration (buf_idx), and the source one (ets_buf_idx).
Introduce a function to configure the chip-level buffer index, and for now
have it simply copy the ETS mapping over to the chip mapping.
Update the ETS handler to project prio_tc to the ets_buf_idx and invoke the
buf_idx recomputation.
Now that there is a canonical place to look for this configuration,
mlxsw_sp_port_headroom_set() does not need to invent def_prio_tc to use if
DCB is compiled out.

mlxsw: spectrum: Unify delay handling between PFC and pause
When a priority is marked as lossless using DCB PFC, or when pause frames
are enabled on a port, mlxsw adds to port buffers an extra space to cover
the traffic that will arrive between the time that a pause or PFC frame is
emitted, and the time traffic actually stops. This is called the delay. The
concept is the same in PFC and pause, however the way the extra buffer
space is calculated differs.
In this patch, unify this handling. Delay is to be measured in bytes of
extra space, and will not include MTU. PFC handler sets the delay directly
from the parameter it gets through the DCB interface.
To convert pause handler, move MLXSW_SP_PAUSE_DELAY to ethtool module,
convert to bytes, and reduce it by maximum MTU, and divide by two. Then it
has the same meaning as the delay_bytes set by the PFC handler.
Keep the delay_bytes value in struct mlxsw_sp_hdroom introduced in the
previous patch. Change PFC and pause handlers to store the new delay value
there and have __mlxsw_sp_port_headroom_set() take it from there.
Instead of mlxsw_sp_pfc_delay_get() and mlxsw_sp_pg_buf_delay_get(),
introduce mlxsw_sp_hdroom_buf_delay_get() to calculate the delay provision.
Drop the unnecessary MLXSW_SP_CELL_FACTOR, and instead add an explanatory
comment describing the formula used.

mlxsw: spectrum: Track priorities in struct mlxsw_sp_hdroom
The mapping from priorities to buffers determines which buffers should be
configured. Lossiness of these priorities combined with the mapping
determines whether a given buffer should be lossy.
Currently this configuration is stored implicitly in DCB ETS, PFC and
ethtool PAUSE configuration. Keeping it together with the rest of the
headroom configuration and deriving it as needed from PFC / ETS / PAUSE
will make things clearer. To that end, add a field "prios" to struct
mlxsw_sp_hdroom.
Previously, __mlxsw_sp_port_headroom_set() took prio_tc as an argument, and
assumed that the same mapping as we use on the egress should be used on
ingress as well. Instead, track this configuration at each priority, so
that it can be adjusted flexibly.
In the following patches, as dcbnl_setbuffer is implemented, it will need
to store its own mapping, and it will also be sometimes necessary to revert
back to the original ETS mapping. Therefore track two buffer indices: the
one for chip configuration (buf_idx), and the source one (ets_buf_idx).
Introduce a function to configure the chip-level buffer index, and for now
have it simply copy the ETS mapping over to the chip mapping.
Update the ETS handler to project prio_tc to the ets_buf_idx and invoke the
buf_idx recomputation.
Now that there is a canonical place to look for this configuration,
mlxsw_sp_port_headroom_set() does not need to invent def_prio_tc to use if
DCB is compiled out.

mlxsw: spectrum: Split headroom autoresize out of buffer configuration
Split mlxsw_sp_port_headroom_set() to three functions.
mlxsw_sp_hdroom_bufs_reset_sizes() changes the sizes of the individual PG
buffers, and mlxsw_sp_hdroom_configure_buffers() will actually apply the
configuration. A third function, mlxsw_sp_hdroom_bufs_fit(), verifies that
the requested buffer configuration matches total headroom size
requirements.
Add wrappers, mlxsw_sp_hdroom_configure() and __..., that will eventually
perform full headroom configuration, but for now, only have them verify the
configured headroom size, and invoke mlxsw_sp_hdroom_configure_buffers().
Have them take the `force` argument to prepare for a later patch, even
though it is currently unused.
Note that the loop in mlxsw_sp_hdroom_configure_buffers() only goes through
DCBX_MAX_BUFFERS. Since there is no logic to configure the control buffer,
it needs to keep the values queried from the FW. Eventually this function
should configure all the PGs.
Note that conversion of __mlxsw_sp_dcbnl_ieee_setets() is not trivial. That
function performs the headroom configuration in three steps: first it
resizes the buffers and adds any new ones. Then it redirects priorities to
the new buffers. And finally it sets the size of the now-unused buffers to
zero. This way no packet drops are introduced.
So after invoking mlxsw_sp_hdroom_bufs_reset_sizes(), tweak the
configuration to keep the old sizes of PG buffers for those buffers whose
size was set to zero.

mlxsw: spectrum: Replace vPorts with Port-VLAN
As explained in the cover letter, since the introduction of the bridge
offload in the mlxsw driver, information related to the offloaded bridge
and bridge ports was stored in the individual port struct,
mlxsw_sp_port.
This lead to a bloated struct storing both physical properties of the
port (e.g., autoneg status) as well as logical properties of an upper
bridge port (e.g., learning, mrouter indication). While this might work
well for simple devices, it proved to be hard to extend when stacked
devices were taken into account and more advanced use-cases (e.g., IGMP
snooping) considered.
This patch removes the excess information from the above struct and
instead stores it in more appropriate structs that represent the bridge
port, the bridge itself and a VLAN configured on the bridge port.
The membership of a port in a bridge is denoted using the Port-VLAN
struct, which points to the bridge port and also member in the bridge
VLAN group of the VLAN it represents. This allows us to completely
remove the vPort abstraction and consolidate many of the code paths
relating to VLAN-aware and unaware bridges.
Note that the FID / vFID code is currently duplicated, but this will
soon go away when the common FID core will be introduced.

mlxsw: spectrum: PTP: Hook into packet receive path
When configured, the Spectrum hardware can recognize PTP packets and
trap them to the CPU using dedicated traps, PTP0 and PTP1.
One reason to get PTP packets under dedicated traps is to have a
separate policer suitable for the amount of PTP traffic expected when
switch is operated as a boundary clock. For this, add two new trap
groups, MLXSW_REG_HTGT_TRAP_GROUP_SP_PTP0 and _PTP1, and associate the
two PTP traps with these two groups.
In the driver, specifically for Spectrum-1, event PTP packets will need
to be paired up with their timestamps. Those arrive through a different
set of traps, added later in the patch set. To support this future use,
introduce a new PTP op, ptp_receive.
It is possible to configure which PTP messages should be trapped under
which PTP trap. On Spectrum systems, we will use PTP0 for event
packets (which need timestamping), and PTP1 for control packets (which
do not). Thus configure PTP0 trap with a custom callback that defers to
the ptp_receive op.
Additionally, L2 PTP packets are actually trapped through the LLDP trap,
not through any of the PTP traps. So treat the LLDP trap the same way as
the PTP0 trap. Unlike PTP traps, which are currently still disabled,
LLDP trap is active. Correspondingly, have all the implementations of
the ptp_receive op return true, which the handler treats as a signal to
forward the packet immediately.

mlxsw: spectrum_router: Do not destroy RIFs based on FID's reference count
Currently, when a RIF is constructed on top of a FID, the RIF increments
the FID's reference count and the RIF is destroyed when the FID's
reference count drops to 1. This effectively means that when no local
ports are member in the FID, the FID is destroyed regardless if the
router port is a member in the FID or not.
The above can lead to the unexpected behavior in which routes using a
VLAN interface as their nexthop device are no longer offloaded after the
last local port leaves the corresponding VLAN (FID).
Example:
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1 offload
# bridge vlan del vid 10 dev swp3
# ip -4 route show dev br0.10
192.0.2.0/24 proto kernel scope link src 192.0.2.1
After the patch, the route is offloaded before and after the VLAN is
removed from local port 'swp3', as the RIF corresponding to 'br0.10'
continues to exists.
In order to remove RIFs' reliance on the underlying FID's reference
count, we need to add a reference count to sub-port RIFs, which are RIFs
that correspond to physical ports and their uppers (e.g., LAG devices).
In this case, each {Port, VID} ('struct mlxsw_sp_port_vlan') needs to
hold a reference on the RIF. For example:
bond0.10
|
bond0
|
+-------+
| |
swp1 swp2
Both {Port 1, VID 10} and {Port 2, VID 10} will hold a reference on the
RIF corresponding to 'bond0.10'. When the last reference is dropped, the
RIF will be destroyed.

mlxsw: spectrum_ptp: Increase parsing depth when PTP is enabled
Spectrum systems have a configurable limit on how far into the packet they
parse. By default, the limit is 96 bytes.
An IPv6 PTP packet is layered as Ethernet/IPv6/UDP (14+40+8 bytes), and
sequence ID of a PTP event is only available 32 bytes into payload, for a
total of 94 bytes. When an additional 802.1q header is present as
well (such as when ptp4l is running on a VLAN port), the parsing limit is
exceeded. Such packets are not recognized as PTP, and are not timestamped.
Therefore generalize the current VXLAN-specific parsing depth setting to
allow reference-counted requests from other modules as well. Keep it in the
VXLAN module, because the MPRS register also configures UDP destination
port number used for VXLAN, and is thus closely tied to the VXLAN code
anyway.
Then invoke the new interfaces from both VXLAN (in obvious places), as well
as from PTP code, when the (global) timestamping configuration changes from
disabled to enabled or vice versa.
