Subject: [PATCH 5.15 060/106] net: hns3: split function hclge_update_port_base_vlan_cfg()

From: Jian Shen <shenjian15@...wei.com>

[ Upstream commit d25f5eddbe1ace18fa95318fd229b07a64ec4353 ]

Currently the function hclge_update_port_base_vlan_cfg() is a
bit long. Split it to several small functions, to improve the
readability.
