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. Miller <davem@davemloft.net>
