The newest device firmware stores IB vs. Ethernet protocol in two bits
in members_count field of multicast group table (0: Infiniband, 1:
Ethernet). When changing the QP members count for a multicast group,
it important not to reset this information. When calling multicast
attach first time, the protocol type should be specified. In this
patch we always set it IB, but in the future we will handle Ethernet
too. When looking for a QP, the protocol type shoud be checked too.

Add a mechanism for mlx4 protocol drivers to get a pointer to other
drivers's device objects. For this, an exported function,
mlx4_get_protocol_dev() is added, which allows a driver to get some
other driver's device based on the protocol that the driver
implements. Two protocols are added: MLX4_PROTOCOL_IB and
MLX4_PROTOCOL_EN.
This will be used in mlx4 IBoE support so that mlx4_ib can find the
corresponding mlx4_en netdev.

The struct mlx4_interface.event() method was supposed to get an enum
mlx4_dev_event, but the driver code was actually passing in the
hardware enum mlx4_event values. Fix up the callers of
mlx4_dispatch_event() so that they pass in the right type of value,
and fix up the event method in mlx4_ib so that it can handle the enum
mlx4_dev_event values.
This eliminates the need for the subtype parameter to the event
method, so remove it.
This also fixes the sparse warning
drivers/net/mlx4/intf.c:127:48: warning: mixing different enum types
drivers/net/mlx4/intf.c:127:48: int enum mlx4_event versus
drivers/net/mlx4/intf.c:127:48: int enum mlx4_dev_event

Add an InfiniBand driver for Mellanox ConnectX adapters. Because
these adapters can also be used as ethernet NICs and Fibre Channel
HBAs, the driver is split into two modules:
mlx4_core: Handles low-level things like device initialization and
processing firmware commands. Also controls resource allocation
so that the InfiniBand, ethernet and FC functions can share a
device without stepping on each other.
mlx4_ib: Handles InfiniBand-specific things; plugs into the
InfiniBand midlayer.
