Add the ability to issue GPCMD_REPORT_KEY and GPCMD_SEND_KEY scsi
commands via the DVD_LU_SEND_RPC_STATE and DVD_HOST_SEND_RPC_STATE
ioctls respectively.
Thus allowing any region protected DVDs mistakenly delivered by Santa
to the wrong region to be viewed on recalcitrant DVD drives (with the
aid of an appropriate utility like regionset).
No change to any current functions.
Found in my hackers@ folder from August.
From netbsd -> Kurt Miller -> jmc@.
