[RFC net-next 2/9] net: hns3: Add "mac table" information query function
From: Salil Mehta
Date: Sun Dec 02 2018 - 18:11:30 EST
From: liuzhongzhu <liuzhongzhu@xxxxxxxxxx>
This patch prints mac table information.
debugfs command:
echo dump mac tbl > cmd
Sample Command:
root@(none)# echo dump mac tbl > cmd
Unicast tab:
|index |mac_addr |vlan_id |VMDq1 |U_M |mac_en |in_port
|0088 |22:22:22:22:22:00 |0000 |0 |0 |0 |2
|0556 |33:33:00:00:00:01 |0000 |1 |1 |1 |0
|2812 |33:33:ff:82:68:17 |0000 |1 |1 |1 |0
|2844 |01:00:5e:00:00:01 |0000 |1 |1 |1 |0
|3368 |c2:f1:c5:82:68:17 |0000 |0 |0 |0 |0
Multicast tab: entry number = 3
|index |mac_addr |UM_MC_RDATA
|0556 |33:33:00:00:00:01 |00000000:00000001:00000000:00000000:00000000
|2812 |33:33:ff:82:68:17 |00000000:00000001:00000000:00000000:00000000
|2844 |01:00:5e:00:00:01 |00000000:00000001:00000000:00000000:00000000
