From 649367735ee5dedb128d9fac0b86ba7e0fe7ae3b Mon Sep 17 00:00:00 2001 From: Matan Barak Date: Thu, 7 Jan 2016 11:19:29 +0200 Subject: [PATCH] IB/cma: Fix RDMA port validation for iWarp cma_validate_port wrongly assumed that Ethernet devices are RoCE devices and thus their ndev should be matched in the GID table. This broke the iWarp support. Fixing that matching the ndev only if we work on a RoCE port.
