From: Rony Efraim <ronye@mellanox.com>
Add netlink directives and ndo entry to allow for controling
VF link, which can be in one of three states:
Auto - VF link state reflects the PF link state (default)
Up - VF link state is up, traffic from VF to VF works even if
the actual PF link is down
Down - VF link state is down, no traffic from/to this VF, can be of
use while configuring the VF
