These are the instructions I get from iscsi maintainer that merged our
code to FreeBSD-11:
1. set WITH_OFED=yes in /etc/make.conf
2. "make buildkernel buildworld installkernel installworld"
3. reboot
4. kldload iser
After that, make sure you configured all the interfaces correctly and
that you have ping between the 2 servers.
later you need to check basic RDMA stuff on your servers (Added
Hans/Oded/Meny to help you if needed).
Only if the above are working you can proceed to check iser.
Max.
