New commands to configure IOV features

I've tried to figure out if there was a standard interface
(ethtool/iproute) through which a user could configure the number
of vfs in his system.

I've seen the RFC suggested in http://markmail.org/thread/qblfcv7zbxsxp7q6,
and http://markmail.org/thread/fw54dcppmxuxoe6n, but failed to see any
later references to it (commits or further discussion on this topic).

How exactly are things standing with these RFCs? Were they abandoned?

Thanks,
Yuval
