Merge branch 'mlx5-fixes' 

Saeed Mahameed says:

====================
Mellanox mlx5 fixes 2017-03-21

This series contains some mlx5 core and ethernet driver fixes.

For -stable:
net/mlx5e: Count LRO packets correctly (for kernel >= 4.2)
net/mlx5e: Count GSO packets correctly (for kernel >= 4.2)
net/mlx5: Increase number of max QPs in default profile (for kernel >= 4.0)
net/mlx5e: Avoid supporting udp tunnel port ndo for VF reps (for kernel >= 4.10)
net/mlx5e: Use the proper UAPI values when offloading TC vlan actions (for kernel >= v4.9)
net/mlx5: E-Switch, Don't allow changing inline mode when flows are configured (for kernel >= 4.10)
net/mlx5e: Change the TC offload rule add/del code path to be per NIC or E-Switch (for kernel >= 4.10)
net/mlx5: Add missing entries for set/query rate limit commands (for kernel >= 4.8)
====================
