dc3a205bc4 Better fix for the errors under high load. Returning CAM_SCSI_BUSY is almost
never correct as CAM has no real understanding of it, and will just immediately
retry the command.  This leads to undesirable cycling of the camisr as well as
a high possibility for the command to exhaust its retries before the driver
can get around to servicing it.

The better fix, as demonstrated here, is to freeze the simq and mark the
command as needing to be tried.  Then when driver can service the command,
the simq gets unfrozen.  This is correct, and documented here to help reduce
the mystery.  However, it also points out a shortcoming in CAM error handling
that makes writing drivers harder.

f1c579b1ec Add the Areca SATA RAID driver (arcmsr). This supports the ARC-11xx and 12xx
series of controllers.  Areca provides a CLI and HTTP management tool for
FreeBSD/i386 and FreeBSD/amd64 on their website.  Many thanks to Areca for
their support of FreeBSD.  Thanks also to Mike Tansca and Sentex Communications
for donating hardware.
