I noticed that doing ibstat, none of the iWARP RNIC adapters were showing up.  I have attached a patch to address the issue (libibumad.patch).

SYS_NODE_TYPE for iWARP RNIC is 4 and is_ib_type only checked to 3.

Before patch is applied:

[root@t4-2 SOURCES]# ibstat
[root@t4-2 SOURCES]#

After patch is applied:

[root@t4-2 libibumad-1.3.7]# ibstat
