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.
