From: Matan Barak <[email protected]>

commit 649367735ee5dedb128d9fac0b86ba7e0fe7ae3b upstream.

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.
