Subject: [net-next 14/15] ixgbevf: Move API negotiation function into mac_ops

From: Alexander Duyck <aduyck@...antis.com>

This patch moves API negotiation into mac_ops.  The general idea here is
that with HyperV on the way we need to make certain that anything that will
have different versions between HyperV and a standard VF needs to be
abstracted enough so that we can have a separate function between the two
so we can avoid changes in one breaking something in the other.
