Subject: [PATCH] net/ice: refact parser API usage
Date: Mon, 4 Apr 2022 05:27:30 -0400 [thread overview]
Message-ID: <20220404092730.129489-1-qi.z.zhang@intel.com> (raw)
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")
