zero. We use this later when the COMPLETE message comes in to set the
final residual count to zero. The flag is reset if the target resumes
a data phase. This obsoletes the `AUTOSAVE' quirk (for this driver).
Also, avoid overwriting the residual count if a SENSE was appended to
the current transaction.
(a) The interrupt is a RESEL interrupt, and
(b) our state is SELECTING.
This condition can occur in perfectly normal operation if we are using
DMA to select the target and we are interrupted by another target
reselecting us. Per discussion with Paul Krannenburg.
we return from the driver expecting to come back due to an
interrupt, because the interrupt might not happen...
Do the untimeout in ncr53c9x_done instead of just before
almost every call to ncr53c9x_done as was done previously.
Make ncr53c9x_sense schedule its own timeout for the new
command it is starting (request sense), separate from the
timeout for the command that just completed.
Some of the stuff (e.g., rarpd, bootpd, dhcpd etc., libsa) still will
only support Ethernet. Tcpdump itself should be ok, but libpcap needs
lot of work.
For the detailed change history, look at the commit log entries for
the is-newarp branch.
