Thanks for the indication of success with 10.1-STABLE. I am locked into using FreeBSD 9.x until I can go through the whole integration and acceptance testing cycle for 10.x, so I’m trying to find a solution that works on in 9.x. I have reviewed the diffs between 9.3 and 10.1-STABLE for ixgbe driver and haven’t noticed anything that stands out.
