From: Qi Zhang Date: Fri, 17 Sep 2021 14:43:04 +0000 (+0800) Subject: net/ice/base: init IMEM table for parser X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=b3e73a812f98b7e8bf18fe2bb545f8c1046ffda2;p=dpdk.git net/ice/base: init IMEM table for parser Parse DDP section ICE_SID_RXPARSER_IMEM into an array of struct ice_imem_item. The Instruction Memory (IMEM) section contains three VLIW instructions for the ALUs, a key extraction instruction for the Parse Graph CAM, and several other fields.
