sys/cam/scsi scsi_da.c
Log:
Automatically detect devices that do not support READ(6)/WRITE(6)
and upgrade to using 10 byte cdbs.
As far as I tested, this works efficiently for most of the
SBP-II/Firewire devices but most of the umass devices still need
ad-hoc work around because umass-sim doesn't return any SCSI errors.
A sysctl nob is also added for the last resort.
I hope we don't need DA_Q_NO_6_BYTE quirks anymore.
