ixgbe: fix large MTU request from VF
[ Upstream commit 63e39d29b3da02e901349f6cd71159818a4737a6 ]
Check that the MTU value requested by the VF is in the supported
range of MTUs before attempting to set the VF large packet enable,
otherwise reject the request. This also avoids unnecessary
register updates in the case of the 82599 controller.
