SATA port multiplier support ready yet?

[Søren Schmidt]

Hi

ATA as such is the same in 6.3+ 7.0 and -current, so yes MFC is a  
definite candidate.

However, lets get it beaten into shape in -current first :)

Rudimentary in that it has all the infrastructure sorted out in ATA,  
but there are features thats not supported yet, such as hotplug/ 
removal, that kind of things. For permanently attached devices it is  
fully functianal for data access etc, on the supported HW.
