Merge branch 'mlx5-fixes'

Saeed Mahameed says:

====================
mlx5 driver updates and fixes

Changes from V0:
	- Dropped: ("net/mlx5e: Reset link modes upon setting speed to zero")
	- Fixed compilation issue introduced to mlx5_ib driver.
	- Rebased to df637193 ('Revert "Prevent NUll pointer dereference with two PHYs on cpsw"')

This series has few bug fixes for mlx5 core and ethernet driver.

Eli fixed a wrong static local variable declaration in flow steering API.
Majd added the support of ConnectX-5 PF and VF and added the support
for kernel shutdown pci callback for more robust reboot procedures.
Maor fixed a soft lockup in flow steering.
Rana fixed a wrog speed define in mlx5 EN driver.
I also had the chance to introduce some bug fixes in mlx5 EN mtu
reporting and handling.

For -stable:
	net/mlx5_core: Fix soft lockup in steering error flow
	net/mlx5e: Device's mtu field is u16 and not int
	net/mlx5e: Fix minimum MTU
	net/mlx5e: Use vport MTU rather than physical port MTU
