Definitely. We have it running now, just with linux.

That is what matters. :) If you use gcc, devel/ccache can improve that a lot. ccache also works with clang, but does not seem very effective. ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

And our goal was making iscsi-over-RDMA and NFS-over-RDMA work. Though at the end we've settled with linux and not using RDMA, because that's kinda messy. When we've tried to do some testin with netcat, no packets were transmitted really. They've got somewhere lost, there had been some error message in the syslog, which i can't recall now.

Yup, present, but not functional :) Hmm, in my local testing we've been able to use the 40G mlxen(4) adapters fine with the OFED stack.

Agreed, it's present. However, it's not in a functional state. Half of the toolkit is missing, and we couldn't get out of the system any better than icmp responses. any other means of communication failed to work.
