From 40fd749245f2ee32874e563051957cc614cf11e4 Mon Sep 17 00:00:00 2001 From: Michal Swiatkowski Date: Fri, 7 Apr 2023 18:52:16 +0200 Subject: [PATCH] ice: remove redundant Rx field from rule info Information about the direction is currently stored in sw_act.flag. There is no need to duplicate it in another field. Setting direction flag doesn't mean that there is a match criteria for direction in rule. It is only a information for HW from where switch id should be collected (VSI or port). In current implementation of advance rule handling, without matching for direction meta data, we can always set one the same flag and everything will work the same. Ability to match on direction meta data will be added in follow up patches. Recipe 0, 3 and 9 loaded from package has direction match criteria, but they are handled in other function. Move ice_adv_rule_info fields to avoid holes.
