Commit Message

Marcin Szycik July 18, 2022, 12:18 p.m. UTC
Add support for creating PPPoE filters in switchdev mode. Add support
for parsing PPPoE and PPP-specific tc options: pppoe_sid and ppp_proto.

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.

ICE COMMS DDP package is required to create a filter as it contains PPPoE
profiles. Added a warning message when loaded DDP package does not contain
required profiles.

Signed-off-by: Marcin Szycik <marcin.szycik@linux.intel.com>
---
v4:
  * adapted code to the redefined ice_tc_pppoe_hdr (session_id is now 
    stored in __be16)
  * removed note about missing support for vlan fields:
    263957263a00 ("ice: switch: dynamically add VLAN headers to dummy packets")
    is already accepted
  * always add an ethtype lookup if PPP/PPPoE options are provided (to 
    prevent setting incorrect ethtype)
  * rebase
v2: wrap one long line
