From 88936e320c1a9971b6b78a38e6bf737e43744f5e Mon Sep 17 00:00:00 2001 From: Peng Li Date: Fri, 12 Feb 2021 11:21:05 +0800 Subject: [PATCH] net: hns3: refactor out hclge_set_vf_vlan_common() To improve code readability and maintainability, separate the command handling part and the status parsing part from bloated hclge_set_vf_vlan_common().
