the number of descriptors, because of a disparity between the
bus_dmamap_load_mbuf implementation in FreeBSD and NetBSD. Now I
cover up the difference using ath_dmamap_load_mbuf.
Thanks Enami Tsugutomo for diagnosing this.
device; some ATAPI devices as master will report 0x7f in all registers
for slave before reset
- For the same reason, remove the er1 check.
Makes slave device with a "strange" ATAPI master probe again.
Problem reported and fix tested by Gary Duzan on current-users.
codes when I right-shift the country-code register! Fixes a bug
reported by Dan Carosone: regulatory domain "ETSI" registered as
domain "Spain/Other", so he could only tune channels 10 and 11.
status from 10 seconds to 250 milli seconds for the second and subsequent
attempts to determine the link status. This prevents unnecessary long
stalls after the device attach routines have completed.
Tested on a dual port QLogic 3212. Approved by mjacob@feral.com.

This adds a device (atabus) between IDE controllers and wd or atapibus, to
have each ATA channel show up in the device tree. Later there will be atabus
devices in /dev, so that we can do IOCTL on them.
Each atabus has its own kernel thread, to handle operations that needs polling,
e.g. reset and others.
Device probing on each bus it defered to the atabus thread creation.
This allows to do the reset and basic device probes in parallel, which reduce
boot time on systems with several pciide controllers.
When probing a nonexistent slave, we may timeout waiting for an interrupt.
In __wdccommand_start(), for polled data in commands, abort quickly if
status still read 0 after 400ns (for a nonexistant slave, the
command will either be aborted, or the status register will report 0; for
a real device we should have BSY, DRQ or ERR).
Thanks to Alexander Yurchenko for reporting the problem and testing the
fix.
removing assumptions that there are only two B channels and by
adding support for a varying number of channels.
Due to this, rename previously used isdn identified "bri" to "isdnif",
which better describes the current situation.
fit in the number of bits used for the port still does something.
This fixes PR pkg/18741 for ac97-based hardware. Other audio drivers
might need a similar fix.
it should be there, but in practice, on some systems an ugly race condition
rears its head: SCSI commands are issued before the FC thread ever runs, and
fail from then on forever. Yuck.
The driver backend is capable of supporting also ISA cards (no DMA)
and primary rate (PRI) cards in addition to the basic rate ones,
but I don't any to test on right now, so we don't support those
currently.

myself for the same company.
