ice: L2TPv3 offload support
Wojciech Drewek says:
Add support for dissecting L2TPv3 session id in flow dissector. Add support
for this field in tc-flower and support offloading L2TPv3. Finally, add
support for hardware offload of L2TPv3 packets based on session id in
switchdev mode in ice driver.
Example filter:
# tc filter add dev $PF1 ingress prio 1 protocol ip \
flower \
ip_proto l2tp \
l2tpv3_sid 1234 \
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 in ice.
COMMS DDP package contains profiles of more advanced protocols.
Without COMMS DDP package hw offload will not work, however
sw offload will still work.
