Subject: [PATCH iwl-next v3 6/6] ice: Add support for PFCP hardware offload in switchdev
Date: Fri, 21 Jul 2023 09:15:32 +0200 [thread overview]
Message-ID: <20230721071532.613888-7-marcin.szycik@linux.intel.com> (raw)
In-Reply-To: <20230721071532.613888-1-marcin.szycik@linux.intel.com>
Add support for creating PFCP filters in switchdev mode. Add support
for parsing PFCP-specific tc options: S flag and SEID.
To create a PFCP filter, a special netdev must be created and passed
to tc command:
ip link add pfcp0 type pfcp
tc filter add dev eth0 ingress prio 1 flower pfcp_opts \
1:123/ff:fffffffffffffff0 skip_hw action mirred egress redirect dev pfcp0
Changes in iproute2 [1] are required to be able to use pfcp_opts in tc.
ICE COMMS package is required to create a filter as it contains PFCP
profiles.

Subject: [Intel-wired-lan] [PATCH iwl-next v3 6/6] ice: Add support for PFCP hardware offload in switchdev
Date: Fri, 21 Jul 2023 09:15:32 +0200 [thread overview]
Message-ID: <20230721071532.613888-7-marcin.szycik@linux.intel.com> (raw)
In-Reply-To: <20230721071532.613888-1-marcin.szycik@linux.intel.com>
Add support for creating PFCP filters in switchdev mode. Add support
for parsing PFCP-specific tc options: S flag and SEID.
To create a PFCP filter, a special netdev must be created and passed
to tc command:
ip link add pfcp0 type pfcp
tc filter add dev eth0 ingress prio 1 flower pfcp_opts \
1:123/ff:fffffffffffffff0 skip_hw action mirred egress redirect dev pfcp0
Changes in iproute2 [1] are required to be able to use pfcp_opts in tc.
ICE COMMS package is required to create a filter as it contains PFCP
profiles.
