I'm sorry I have not been able to get to this yet, but putting food on the table comes first so the FreeBSD work that Intel pays me for has to come first. Also your driver work is based on a version that is too old to just accept, I am hoping to get the STABLE tree converted to the new shared code that CURRENT has shortly, so whatever good ideas you have, and I'm sure you have many, will need to be made into the new code base. Furthermore, that base is a moving target as I add new hardware support. In the near term I will be taking changes that I did for the 10G Oplin driver, specifically multiqueue/rss and the lock splitting that is in that driver, and putting them back into the Gig driver, but that should go into CURRENT first. My recomendation is to move your work to CURRENT.
