Thanks for the list.

There is no PCI-X support on the server boards I have in mind, so I can only
validate PCI-E adapters.

There's a twa driver in sys/dev/raid/ but it has not been updated since 2004,
so I guess none of the recent 3Ware adapters are supported.

There's also a mpt driver in sys/dev/disk/ which has been recently updated. No
trace of a mfi driver.

I will focus on LSI external adapters for now.
