Subject[PATCH 4.9 070/109] RDMA/qedr: Fix RDMA CM loopback
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ram Amrani <Ram.Amrani@Cavium.com>


[ Upstream commit af2b14b8b8ae21b0047a52c767ac8b44f435a280 ]

The loopback logic in RDMA CM packets compares Ethernet addresses and
was accidently inverse.
