Commit Message

Zhang, Qi Z April 4, 2022, 9:27 a.m. UTC
Not necessary to create / destroy a parser instance for every raw packet
rule. A global parser instance will be created in ice_flow_init and be
destroyed in ice_flow_uninit.

Also, ice_dev_udp_tunnel_port_add has been hooked to perform corresponding
parser configure. This also fix the issue that RSS engine can't support
VXLAN inner through raw packet filter.

Fixes: 1b9c68120a1c ("net/ice: enable protocol agnostic flow offloading in RSS")
