X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=d603c809ef91fa2d211bde5e95be417847410379;p=linux-beck.git

IB/mlx5: Fix decision on using MAD_IFC

Fix the condition that dictates when MAD_IFC should be used. According
to firmware specifications, MAD_IFC commands must be used only if the
ib_virt capability is off.
