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 vf 6 MAC 36:c3:25:02:65:c5, vlan 300, spoof checking on, link-state auto The system is: $ lsb_release -a No LSB modules are available.
