Subject: [PATCH AUTOSEL 5.6 066/149] RDMA/siw: Fix setting active_mtu attribute

From: Kamal Heib <kamalheib1@...il.com>

[ Upstream commit beb205dd67aaa4315dedf5c40b47c6e9dee5a469 ]

Make sure to set the active_mtu attribute to avoid report the following
invalid value:

$ ibv_devinfo -d siw0 | grep active_mtu
			active_mtu:		invalid MTU (0)

Fixes: 303ae1cdfdf7 ("rdma/siw: application interface")
