	This patch adds MSI-X support to MLX4 driver.
	To remind, current driver creates 2 EQs (for commands/events and
completions), which both use 1 legacy interrupt.
	With this patch MLX4 requests (in inf file) 18 MSI-X interrupt
vectors, spreaded across processors in round-robin way.
	If the platform doesn't support MSI-X vectors, the driver uses
legacy interrupts.
	 
	MSI-X support required some changes in the card reset mechanism,
which is also found in the patch.
