[ISP] QLA2432 Target Mode Broken

[Sean Bruno]

I tried putting a 2432 into target mode this week and noted that the 
system threw a pretty nice panic and thought I would post the output 
here.  Reviewing the 4G documentation from Qlogic, it looks like they've 
substantially changed the target mode interface, so I'm not surprised 
that there's some work to do.  If anyone has any patches they'd like me 
to test, I'm open to integration:
