====================
ptp: convert remaining users of .adjfreq
A handful of drivers remain which still use the .adjfreq interface instead
of the newer .adjfine interface. The new interface is preferred as it has a
more precise adjustment using scaled parts per million.
A handful of the remaining drivers are implemented with a common pattern
that can be refactored to use the adjust_by_scaled_ppm and
diff_by_scaled_ppm helper functions. These include the ptp_phc, ptp_ixp64x,
tg3, hclge, stmac, cpts and bnxt drivers. These are each refactored in a
separate change.
The remaining drivers, bnx2x, liquidio, cxgb4, fec, and qede implement
.adjfreq in a way different from the normal pattern expected by
adjust_by_scaled_ppm. Fixing these drivers to properly use .adjfine requires
specific knowledge of the hardware implementation. Instead I simply refactor
them to use .adjfine and convert scaled_ppm into ppb using the
scaled_ppm_to_ppb function.
Finally, the .adjfreq implementation interface is removed entirely. This
simplifies the interface and ensures that new drivers must implement the new
interface as they no longer have an alternative.
This still leaves parts per billion used as part of the max_adj interface,
and the core PTP stack still converts scaled_ppm to ppb to check this. I
plan to investigate fixing this in the future.

Convert all remaining drivers that still use .adjfreq to the newer .adjfine

non-standard methods of programming their hardware. They are all converted
to use scaled_ppm_to_ppb to get the parts per billion value that their
logic depends on.

When the BNXT_FW_CAP_PTP_RTC flag is not set, the bnxt driver implements
.adjfreq on a cyclecounter in terms of the straightforward "base * ppb / 1
billion" calculation. When BNXT_FW_CAP_PTP_RTC is set, the driver forwards
the ppb value to firmware for configuration.
Convert the driver to the newer .adjfine interface, updating the
cyclecounter calculation to use adjust_by_scaled_ppm to perform the
calculation. Use scaled_ppm_to_ppb when forwarding the correction to
firmware.

Add support for xdp in lan966x driver. Currently only XDP_PASS and

The first 2 patches are just moving things around just to simplify
the code for when the xdp is added.
Patch 3 actually adds the xdp. Currently the only supported actions
are XDP_PASS and XDP_DROP. In the future this will be extended with
XDP_TX and XDP_REDIRECT.
Patch 4 changes to use page pool API, because the handling of the
pages is similar with what already lan966x driver is doing. In this
way is possible to remove some of the code.
All these changes give a small improvement on the RX side:

Extend TC key support for Sparx5 IS2 VCAP
This provides extended tc flower filter key support for the Sparx5 VCAP
functionality.
It builds on top of the initial IS2 VCAP support found in this series:
https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/
Overview:
=========
The added flower filter key (dissector) support is this:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
The IS2 VCAP supports classified VLAN information which amounts to the
outer VLAN info in case of multiple tags.
Functionality:
==============
Before frames can match IS2 VCAP rules with e.g an IPv4 source address, the
IS2 VCAPs keyset configuration must include keyset that contains a IPv4
source address and this must be configured for the lookup/port/traffic-type
that you want to match on.
The Sparx5 IS2 VCAP has the following traffic types:
- Non-Ethernet frames
- IPv4 Unicast frames
- IPv4 Multicast frames
- IPv6 Unicast frames
- IPv6 Multicast frames
- ARP frames
So to cover IPv4 traffic the two IPv4 categories must be configured with a
keyset that contains IPv4 address information such as the
VCAP_KFS_IP4_TCP_UDP keyset.
The IPv4 and IPv6 traffic types are configured with useful default keysets,
in later series we will use the tc template functionality when we want to
change these defaults.
The flower filter must contain a goto action as its last action and the
chain id must specify the chain id of the next lookup in a VCAP or a
destination outside the VCAP ranges.
To activate the VCAP lookups on a port you must add a TC matchall filter on
the port containing a single goto action that points to the chain id of the
first lookup in the IS2 VCAP.
From then on frames arriving on this port will be matched against the
rules in the IS2 VCAP lookups.
Removing the matchall filter will deactivate the IS2 lookups, but will
leave the VCAP rules in the memory of the VCAP instance, and from then in
frames will no longer be matched against the rules the in IS2 VCAP.
If the matchall rule is added back again the IS2 rules will be active
once more.
Delivery:
=========
This is current plan for delivering the full VCAP feature set of Sparx5:
- TC flower filter statistics and rule order by size and priority
- debugfs support for inspecting rules
- support for TC protocol all
- Sparx5 IS0 VCAP support
- add TC policer and drop action support (depends on the Sparx5 QoS support
upstreamed separately)
- Sparx5 ES0 VCAP support
- TC flower template support
- TC matchall filter support for mirroring and policing ports
- TC flower filter mirror action support
- Sparx5 ES2 VCAP support
Version History:
================
v6 Rebased on the latest next-next master branch.
No other implementation changes.
v5 Add support for a TC matchall filter with a single goto action
which will activate the lookups of the VCAP. Removing this filter
will deactivate the VCAP lookups again.
v4 Add support for TC flower filter goto action and a check of the
actions: check action combinations and the goto chain id.
v3 Add some more details to the explanation in the commit message
about support for MAC_ETYPE keysets and "protocol all" as well as
the classified VLAN information. This is done to help testing the
feature.
No implementation changes in this version.
v2 Split one of the KUNIT tests into 3 tests to fix a kernel robot
build warning.

Use a tc matchall rule with a goto action to the VCAP specific chain to
enable the VCAP lookups.
If the matchall rule is removed the VCAP lookups will be disabled
again using its cookie as lookup to find the VCAP instance.
To enable the Sparx5 IS2 VCAP on eth0 you would use this command:
tc filter add dev eth0 ingress prio 5 handle 5 matchall \
skip_sw action goto chain 8000000
as the first lookup in IS2 has chain id 8000000

This adds the following TC flower filter keys to Sparx5 for IS2:
- ipv4_addr (sip and dip)
- ipv6_addr (sip and dip)
- control (IPv4 fragments)
- portnum (tcp and udp port numbers)
- basic (L3 and L4 protocol)
- vlan (outer vlan tag info)
- tcp (tcp flags)
- ip (tos field)
as well as an 128 bit keyfield interface on the VCAP API to set the IPv6
addresses.
IS2 supports the classified VLAN information which amounts to the outer
VLAN info in case of multiple tags.
Here are some examples of the tc flower filter operations that are now
supported for the IS2 VCAP:
- IPv4 Addresses
tc filter add dev eth12 ingress chain 8000000 prio 12 handle 12 \
protocol ip flower skip_sw dst_ip 1.0.1.1 src_ip 2.0.2.2 \
action trap action goto chain 81000000
- IPv6 Addresses
tc filter add dev eth12 ingress chain 8000000 prio 13 handle 13 \
protocol ipv6 flower skip_sw dst_ip 1::1:1 src_ip 2::2:2 \
action trap action goto chain 81000000
- IPv4 fragments
tc filter add dev eth12 ingress chain 8000000 prio 14 handle 14 \
protocol ip flower skip_sw dst_ip 3.0.3.3 src_ip 2.0.2.2 \
ip_flags frag/nofirstfrag action trap action goto chain 81000000
- TCP and UDP portnumbers
tc filter add dev eth12 ingress chain 8000000 prio 21 handle 21 \
protocol ip flower skip_sw dst_ip 8.8.8.8 src_ip 2.0.2.2 \
ip_proto tcp dst_port 100 src_port 12000 action trap action goto

tc filter add dev eth12 ingress chain 8000000 prio 23 handle 23 \
protocol ipv6 flower skip_sw dst_ip 5::5:5 src_ip 2::2:2 \
ip_proto tcp dst_port 300 src_port 13000 action trap action goto
chain 81000000
- Layer 3 and Layer 4 protocol info
tc filter add dev eth12 ingress chain 8000000 prio 28 handle 28 \
protocol ipv4 flower skip_sw dst_ip 9.0.9.9 src_ip 2.0.2.2 \
ip_proto icmp action trap action goto chain 81000000
- VLAN tag info (outer tag)
tc filter add dev eth12 ingress chain 8000000 prio 29 handle 29 \
protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 6 \
vlan_ethtype ipv4 action trap action goto chain 81000000
tc filter add dev eth12 ingress chain 8000000 prio 31 handle 31 \
protocol 802.1q flower skip_sw vlan_id 600 vlan_prio 5 \
vlan_ethtype ipv6 action trap action goto chain 81000000
- TCP flags
tc filter add dev eth12 ingress chain 8000000 prio 15 handle 15 \
protocol ip flower skip_sw dst_ip 4.0.4.4 src_ip 2.0.2.2 \
ip_proto tcp tcp_flags 0x2a/0x3f action trap action goto chain
81000000
- IP info (IPv4 TOS field)
tc filter add dev eth12 ingress chain 8000000 prio 16 handle 16 \
protocol ip flower skip_sw ip_tos 0x35 dst_ip 5.0.5.5 \
src_ip 2.0.2.2 action trap action goto chain 81000000
Notes:
- The "protocol all" selection is not supported yet.
- The MAC address rule now needs to use non-ip and non "protocol all". Here
is an example:
tc filter add dev eth12 ingress chain 8000000 prio 10 handle 10 \
protocol 0xbeef flower skip_sw \
dst_mac 0a:0b:0c:0d:0e:0f \
src_mac 2:0:0:0:0:1 \
action trap action goto chain 81000000
- The VLAN rules use classified VLAN information, and to get the
classification information into the frame metadata, the ingress port need
to be added to a bridge with the VID and vlan filtering enabled, like
this (using VID 600 and four ports eth12, eth13, eth14 and eth15):
ip link add name br5 type bridge
ip link set dev br5 up
ip link set eth12 master br5
ip link set eth13 master br5
ip link set eth14 master br5
ip link set eth15 master br5
sysctl -w net.ipv6.conf.eth12.disable_ipv6=1
sysctl -w net.ipv6.conf.eth13.disable_ipv6=1
sysctl -w net.ipv6.conf.eth14.disable_ipv6=1
sysctl -w net.ipv6.conf.eth15.disable_ipv6=1
sysctl -w net.ipv6.conf.br5.disable_ipv6=1
ip link set dev br5 type bridge vlan_filtering 1
bridge vlan add dev eth12 vid 600
bridge vlan add dev eth13 vid 600
bridge vlan add dev eth14 vid 600
bridge vlan add dev eth15 vid 600

HINIC is marked orphan for 14 months from the commit "5cfe5109a1d7",
but there are lots of HINIC in use.
I have a SP582 NIC (hi1822 inside which is a kind of HINIC SOC),
and implement based on hinic driver, and if there are some patches
for HINIC, I can test and do some code review.
I'm active in linux contribution, if possible,
I want to take the hinic maintainership.
Add my email here to receive patches.
