From c55b1ba93f070d14eeb86e11fa03480a3b2d671d Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Fri, 17 Sep 2021 22:43:06 +0800 Subject: [PATCH] net/ice/base: init parse graph CAM table for parser Parse DDP section ICE_SID_RXPARSER_CAM or ICE_SID_RXPARSER_PG_SPILL into an array of struct ice_pg_cam_item. Parse DDP section ICE_SID_RXPARSER_NOMATCH_CAM or ICE_SID_RXPARSER_NOMATCH_SPILL into an array of struct ice_pg_nm_cam_item.
