Merge branch 'mlx5-fixes'

Saeed Mahameed says:

====================
mlx5 tx timeout watchdog fixes

This patch set provides two trivial fixes for the tx timeout series lately
applied into net 4.7.

From Daniel, detect stuck queues due to BQL
From Mohamad, fix tx timeout watchdog false alarm

Hopefully those two fixes will make it to -stable, assuming
3947ca18

 ('net/mlx5e: Implement ndo_tx_timeout callback') was also backported to -stable.
