ice: Add support for PPPoE hardware offload
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.
