Obviously, they cannot be MFC-ed to 7-STABLE Err, I think you are confused. I made changes back at the end of 2008 to H= EAD=20 only that made hints always reserve unit numbers. 7.x has never had those= =20 changes. My earlier changes made network devices in 8.0 change from le0 to= =20 le1 in certain VMs. This commit now lets them use le0 as 7.x and earlier=20 releases do. In fact, that was was the primary reason for this commit, to= =20 avoid breaking POLA for 8.0. =2D-=20 John Baldwin
