Subject: [Intel-wired-lan] [RFC PATCH net-next v3 0/4] ice: PPPoE offload support
Date: Wed, 29 Jun 2022 16:38:55 +0200 [thread overview]
Message-ID: <20220629143859.209028-1-marcin.szycik@linux.intel.com> (raw)
Add support for dissecting PPPoE and PPP-specific fields in flow dissector:
PPPoE session id and PPP protocol type. Add support for those fields in
tc-flower and support offloading PPPoE. Finally, add support for hardware
offload of PPPoE packets in switchdev mode in ice driver.
Example filter:
tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \
1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR
Changes in iproute2 are required to use the new fields (will be submitted
soon).
ICE COMMS DDP package is required to create a filter in ice.
Note: currently matching on vlan + PPPoE fields is not supported. Patch [0]
will add this feature.
[0] https://patchwork.ozlabs.org/project/intel-wired-lan/patch/20220420210048.5809-1-martyna.szapar-mudlaw@intel.com
v3: revert byte order changes in is_ppp_proto_supported from previous
version, add kernel-doc for is_ppp_proto_supported, add more CC
v2: cosmetic changes

net/sched: flower: Add PPPoE filter
flow_offload: Introduce flow_match_pppoe
