From ea73e4e66c6ce528c04ba6638e5c843d99377fda Mon Sep 17 00:00:00 2001 From: Andy Grover Date: Thu, 20 Aug 2009 14:43:05 -0700 Subject: [PATCH] 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.
