Help to make iSER working

[Max Gurtovoy]

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.
