X-Git-Tag: v4.9.8~5678^2~40

mlx4: Fix wrong endianess access with QP context flags

We wrongly tested QP context bits without BE conversion
as was spotted by sparse...

drivers/infiniband/hw/mlx4/qp.c:1685:38: sparse: restricted __be32 degrades to integer

Fix that!

Fixes: d2fce8a ('mlx4: Set user-space raw Ethernet QPs to properly handle VXLAN traffic')
