From: Qi Zhang Date: Mon, 15 Jun 2020 02:04:53 +0000 (+0800) Subject: net/ice/base: fix advanced switch rule stale information X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=94c81be833c82885fa2270d06904b7304634016d;p=dpdk.git net/ice/base: fix advanced switch rule stale information To avoid having stale information about "adv_rule" per recipe, when all rules associated to a given recipe are deleted, reset the "adv_rule" flag otherwise it causes problem later on when decisions about filter rules being present or not are made based on "adv_rule" flag. Removed setting "adv_rule = 1" when recipe is created. It is set correctly when advanced switch rule is added referring to the recipe which was created as a result of adding advanced switch rule.
