Miller" <davem@...emloft.net>, Sasha Levin <sashal@...nel.org> Subject: [PATCH 5.18 072/141] net: hns3: fix PF rss size initialization bug From: Jie Wang <wangjie125@...wei.com> [ Upstream commit 71b215f36dca1a3d5d1c576b2099e6d7ea03047e ] Currently hns3 driver misuses the VF rss size to initialize the PF rss size in hclge_tm_vport_tc_info_update. So this patch fix it by checking the vport id before initialization.
