Subject: [PATCH v4 net-next 05/10] net/ncsi: Ethtool operation to get NCSI channel info
This adds ethtool command (ETHTOOL_GNCSICINFO) to retrieve the
NCSI channel information for the specified one. The simplified
output of this command is shown as follows from the modified
(private) ethtool:
# ethtool --ncsi eth0 info
NCSI channel 0:0 version:
version: 00000000
alpha2: 00000000
f/w name:
f/w version: 00000000
PCI IDs: 0000 0000 0000 0000
Manufacture ID: 00000000
Generic capability: 0000000f (0000000f)
Multicast capability: 00000007 (00000000)
Buffer capability: 00004000
AEN capability: 00000007 (00000000)
VLAN capability: 00000007 (00000000)
Filters: VLAN (2), Mixed (0), MC (2), UC (4)
Link status: 000ff66b 00000000 00000000
MAC filter entries:
00:00:00:00:00:00
48:c4:b6:f0:a6:d4
b6:fa:8f:70:00:00
00:00:00:01:07:34
VLAN filter entries:
0004
bc84
