I guess you now hit the bug 6716683. http://bugs.opensolaris.org/view_bug.do?bug_id=6716683 ixgbe tx could send package larger than max_frame_size
This bug sometimes causes traffic problems when a large packet is passed to the driver (e.g jumbo frame or lso frame). There is no workaround for it, but I will put-back the fix along with the lso support soon.
