[Bug 335615] Re: Marvell 88SE6121 not supported

[Stephen Hemminger]

Marvell devices on ASUS P6-T are:

07:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12)
08:00.0 IDE interface: Marvell Technology Group Ltd. 88SE6121 SATA II Controller (rev b2)
09:00.0 RAID bus controller: Marvell Technology Group Ltd. Device 6440 (rev 02)
0a:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8056 PCI-E Gigabit Ethernet Controller (rev 12)

The one the bug is about is:

Just enabling CONFIG_SCSI_MVSAS gets the correct driver.
I even extracted driver from kernel source and built it standalone, and that worked as well.
