[PATCH rdma-rc 2/3] IB/mlx5: Fix RoCE Address Path fields

[Leon Romanovsky <leon-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>]

From: Majd Dibbiny <majd-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>

When working over a RoCE network, the UDP source port should be set only
for statically connected QPs (RC, UC and XRC).

Fixes: 2811ba51b049 ("IB/mlx5: Add RoCE fields to Address Vector")
