[ewg] [PATCH] IPOIB/CM Increase retry counts for OFED-1.3

[Pradeep Satyanarayana]

This patch change retry counts to small values. This helps interoperability
between ehca and mthca. Without this patch I had seen "send completion errors".

Or Gerlitz has started a thread on the general mailing list and the complete
discussion will be available there. This is the second part of the patch
submitted yesterday and is split up as per Eli's request.
