Small code cleanup:
1. change MLX4_DEV_CAP_FLAGS2_REASSIGN_MAC_EN to MLX4_DEV_CAP_FLAG2_REASSIGN_MAC_EN
2. put MLX4_SET_PORT_PRIO2TC and MLX4_SET_PORT_SCHEDULER in the same union with the
other MLX4_SET_PORT_yyy

Mellanox ConnectX architecture is: mlx4_core is the lower level
PCI driver which register on the PCI id, and protocol specific drivers
are depended on it: mlx4_en - for Ethernet and mlx4_ib for Infiniband.
NIC could have multiple ports which can change their type dynamically.
We use the request_module() call to load the relevant protocol driver
when needed: on loading time or at port type change event.
