[PATCH] [RFC] [SCSI] mpt fusion: add support for 0x1000/0x0055

The device identifies itself as

0d:05.0 SCSI storage controller: LSI Logic / Symbios Logic SAS1068 PCI-X Fusion-MPT SAS (rev 01) Subsystem: NEC Corporation SAS1068

and seems to be functionally compatible with 0x0054 PID.

The request for support of this device has been raised on mailinglists several
times in the past (see [1] [2] and more), but aparently the PCI ID never made it
to mptsas_pci_table[].

I guess the "Subsystem: NEC Corporation" is telling us some rebranding
story, including the PID change ... ?

NACK.

Vendor 0x1000, Device id 0x0055 is actually an old LSI MegaRAID 1068
based software raid board. This device was never qualified nor
intended to be used with the mpt fusion driver.

So, what is the alternative?

The only thing I know is that it works at least in basic mode (haven't
tested performance at all).
