A) Fibre Channel Target Mode support mostly works (SAS/SPI won't be too far behind). I'd say that this probably works just about as well as isp(4) does right now. Still, it and isp(4) and the whole target mode stack need a bit of tightening. B) The startup sequence has been changed so that after all attaches are done, a set of enable functions are called. The idea here is that the attaches do whatever needs to be done *prior* to a port being enabled and the enables do what need to be done for enabling stuff for a port after it's been enabled. This means that we also have events handled by their proper handlers as we start up. C) Conditional code that means that this driver goes back all the way to RELENG_4 in terms of support. D) Quite a lot of little nitty bug fixes- some discovered by doing RELENG_4 support. We've been living under Giant *waaaayyyyy* too long and it's made some of us (me) sloppy. E) Some shutdown hook stuff that makes sure we don't blow up during a reboot (like by the arrival of a new command from an initiator). There's been some testing and LINT checking, but not as complete as would be liked. Regression testing with Fusion RAID instances has not been possible. Caveat Emptor. Sponsored by: LSI-Logic.
