Thanks David,

The kbuild bot caught a build error where the add/kill callbacks aren't
defined without CONFIG_NET_NCSI:

>> ERROR: "ncsi_vlan_rx_kill_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined!
>> ERROR: "ncsi_vlan_rx_add_vid" [drivers/net/ethernet/faraday/ftgmac100.ko] undefined!

It's a quick fixup to patch 3 as below, would you like me to send it as a v4?
