ixgbe/ix sysctl missing in FreeBSD 9.2

[Jack Vogel]

Make sure you are in slots with enough lanes/bandwidth, the driver should
complain when loaded
if you aren't though. Make sure you aren't getting interrupts throttled,
and that you have sufficient
mbuf resources so you aren't waiting on those, that can make a BIG
difference.
