From: Sasha Levin
Date: Sat Apr 11 2020 - 19:37:54 EST


From: Kamal Heib <kamalheib1@xxxxxxxxx>

[ 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)
