Public bug reported:
'ip link' behaves strangely when trying to set both vlan and mac for a
VF.
Consider the following example:
$ sudo ip link set p2p1 vf 6 mac 36:c3:25:02:65:c4 vlan 300
$ ip link show p2p1
189: p2p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
group default qlen 1000
link/ether 0c:c4:7a:1e:ac:0e brd ff:ff:ff:ff:ff:ff
vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 2 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 3 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 4 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 5 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 6 MAC 36:c3:25:02:65:c4, spoof checking on, link-state auto
As you can see, it was able to set MAC address, but silently ignored VLAN
setting.
Now comes the interesting part, if I specify vlan first and then mac, things
work:
$ sudo ip link set p2p1 vf 6 vlan 300 mac 36:c3:25:02:65:c5
$ ip link show p2p1
189: p2p1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT
group default qlen 1000
link/ether 0c:c4:7a:1e:ac:0e brd ff:ff:ff:ff:ff:ff
vf 0 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 1 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 2 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 3 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 4 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
vf 5 MAC 00:00:00:00:00:00, spoof checking on, link-state auto
