if_link: Add additional parameter to IFLA_VF_INFO for spoof checking
Add configuration setting for drivers to turn spoof checking on or off
for discrete VFs.
v2 - Fix indentation problem, wrap the ifla_vf_info structure in
#ifdef __KERNEL__ to prevent user space from accessing and
change function paramater for the spoof check setting netdev
op from u8 to bool.
v3 - Preset spoof check setting to -1 so that user space tools such
as ip can detect that the driver didn't report a spoofcheck
setting. Prevents incorrect display of spoof check settings
for drivers that don't report it.
