Subject: [RFC net-next 3/9] net: hns3: Add "port vlan table" information query function
From: liuzhongzhu <liuzhongzhu@...wei.com>
This patch prints port vlan table information.
debugfs command:
echo dump port vlan tbl > cmd
Sample Command:
root@(none)# echo dump port vlan tbl > cmd
vlan | port filter bitMap:
0000 | 00000000:00000000:00000000:00000000:00000000:00000001
root@(none)#
