[ewg] T3 change needed for OFED-1.5.4

[Steve Wise]

Hey Sean,

Do you remember we pulled out 2 upstream rping fixes in ofed-1.5.2 (or maybe 1.5.3) because of a regression that was due 
to a change in iw_cxgb3/libcxgb3 that was not included in 1.5.2.  The commits are below.  Anyway, I want to pull this 
iw_cxgb3/libcxgb3 change into OFED-1.5.4 and I'll need the 2 rping fixes pulled in also.

We need this because the T4 iwarp driver/lib has this same functionality that isn't in the OFED T3 code. With this 
functionality, rping is broken and needs the 2 librdmacm fixes.  However, if you pull in the 2 librdmacm fixes, then the 
existing T3 code will cause rping to hang, I think, which is why we pulled the rping changes from OFED-1.5.2.  So we 
need to bring T3 up to date, and get these librdmacm fixes pulled in.

Can you please submit the librdma release that includes these rping changes once we get the T3 changes included?

Here are the details:

We need this iw_cxg3 upstream fix.  Chelsio will do this asap.
