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? --HPS
