Hi,

The most simple way is to pull this driver from Linux 4.9, including 
libcxgb for user-space, if possible, though I'm not sure about the 
FreeBSD specific areas of iWarp and socket handling. I think you know 
that part better than I do.

After pulling from Linux 4.9 you need to extend this change to cover the 
iw_cxgb:

https://svnweb.freebsd.org/changeset/base/330508

Or can you retire iw_cxgb?
