        src/sys/dev/pci/ixgbe: ixgbe.c

Log Message:
 Fix a bug that media change may fail. I noticed that ifconfig ixgN media XXX
took a 10 or more seconds on a Denverton machie. I occurred by trying take a
lock and timed out. The reason was that ixgbe_media_change() didn't take
CORE_LOCK. Do it.

 This problem was from FreeBSD's pre-iflib ixgbe (I don't know whether this
problem really occurs on FreeBSD or not). Post-iflib ixgbe has no problem
because iflib_media_change() takes a lock.
