From e0b6178773cf0aadff636b7cc678169c05ba825c Mon Sep 17 00:00:00 2001 From: Jian Shen Date: Thu, 22 Dec 2022 14:43:43 +0800 Subject: [PATCH] net: hns3: fix VF promisc mode not update when mac table full [ Upstream commit 8ee57c7b8406c7aa8ca31e014440c87c6383f429 ] Currently, it missed set HCLGE_VPORT_STATE_PROMISC_CHANGE flag for VF when vport->overflow_promisc_flags changed. So the VF won't check whether to update promisc mode in this case. So add it.
