From 6bad5047be24b6884ac90ac0a9436924a8142dd5 Mon Sep 17 00:00:00 2001 From: Qi Zhang Date: Mon, 15 Jun 2020 10:04:50 +0800 Subject: [PATCH] net/ice/base: return correct error code Return ICE_ERR_DOES_NOT_EXIST return code if admin command error code is ICE_AQ_RC_ENOENT (not exist). ice_aq_sw_rules is used when switch rule is getting added/deleted/updated. In case of delete/update switch rule, admin command can return ICE_AQ_RC_ENOENT error code if such rule does not exist, hence return ICE_ERR_DOES_NOT_EXIST error code from ice_aq_sw_rule, so that caller of this function can decide how to handle ICE_ERR_DOES_NOT_EXIST. Allow proper cleanup of internal data structures from ice_rem_adv_rule function if ice_aq_sw_rules return error code ICE_ERR_DOES_NOT_EXIST otherwise per recipe:rule list will never become empty.
