Small bounty on porting HBA mode to mfii driver

[David Brownlee <abs%absd.org@localhost>]

Would anyone be interested in a small amount of ${beverage} monies for porting physical disk/HBA mode support to the mfii driver? I understand its available in the OpenBSD driver from which mfii was ported.

Can setup remote console access via iDrac on a Dell T440 for testing if that helps :)

Thanks

David
