twa(4) update to support 9550SXU/9590SE controllers

[freebsd at bitfreak.org]

I just noticed that, based on the commit logs, the twa(4) driver is 
still the driver from the 9.3.0.1 release from 3ware.  That version 
doesn't support the new 9550SXU and 9590SE controllers, the later being 
3ware's new PCI Express card.  Is anyone currently planning/testing an 
update to the 9.3.0.7 release?  I tried emailing the only address listed 
(vkashyap) in the logs and source, but it bounced.  So I'm not sure who 
contact.  Should this wait until after the 6.2 release?
