Subject: [PATCH] {net,IB}/mlx5: mlx5_ifc updates

Introducing mlx5_ifc updates for upcoming ConnectX-4 features.

Needed bits and hardware structures for mlx5e netdev:
	- MLX5_CQ_PERIOD_NUM_MODES for adaptive moderation
	  support
	- QoS rate limiting
	- SQ context rate limiting
	- Auto negotiation fields in PTYS register
	- Source SQN field in flow table entry match structure
	- DCBX parameters

Needed bits and hardware structures for IB:
	- New XRQ opcodes, commands and capabilities layout
	- Extend q counters definition to support IB.
