From 0514f8a9c0cbd26afa70dc56406cc0ee1e134dcf Mon Sep 17 00:00:00 2001 From: Andy Grover <andy.grover@oracle.com> Date: Fri, 30 Oct 2009 08:51:56 +0000 Subject: RDS: Do not send congestion updates to loopback connections This issue was discovered by HP's Pradeep and fixed in OFED 1.3, but not fixed in later versions, since the fix's implementation was not immediately applyable to the later code. This patch should do the trick for 1.4+ codebases. Signed-off-by: Andy Grover <andy.grover@oracle.com> Signed-off-by: David S.
