mlx4_core: Handle multi-physical function devices
MT26468 (PCI ID 0x6764) devices can expose multiple physical functions. The current driver only handles the primary physical function. For other functions, the QUERY_FW firmware command will fail with the CMD_STAT_MULTI_FUNC_REQ error code. Don't try to drive such devices, but print a message saying the driver is skipping those devices rather than just "QUERY_FW command failed." Signed-off-by: Yevgeny Petrilin <yevgenyp@mellanox.co.il> [ Rather than keeping unsupported devices bound to the driver, simply print a more informative error message and exit - Roland ] Signed-off-by: Roland Dreier <rolandd@cisco.com>
