this consistently, and it doesn't always work even when the chip
supports it.
- Make sure things DMA'd to the chip that the chip interprets are in
little-endian mode.
Clean up some isp_attach time stuff- if ISP2100_FABRIC is defined try *really*
hard to make sure that we get the firmware state to FW_READY and see the

this it's unlikely we will be able to correctly query the nameserver because
we won't see that we're on a fabric.
Clean up the completely broken and stupid attempts to hot switch the

panic from the mbuf cluster pool shortly after a resume. The cluster
in question contained a valid 82557 receive descriptor and an IP

suspend/resume cycle or two.
Changes:
- in interrupt handler, if the interface isn't in IFF_RUNNING state,
just ack interrupts and return; don't try to receive packets, queue
new descriptors, etc., etc.,
- add power control hook to take interface down on suspend,
and restart it (if it was up) on resume.
- tweaks to fxp_stop and fxp_shutdown to avoid recursive panics due
to the (now fixed) bug.
- Don't trust HA_ST_MORE again if the above situation occurs.
- Nuke bitfields in 'struct eata_sp'.
- Don't bother using scatter-gather if DMA map contains only 1 segment.
- Return TRY_AGAIN_LATER and not COMPLETE if an EATA command times out.
- Check SCSI status in dpt_inquire(), not just HBA status.

Redo how we start commands- do a 'slow' start function which then

- Correct the way the MAC address is read from the SROM, after re-reading

Other semi-related changes:
- Differentiate between MX98715 and MX98715A.
- Improve the Macronix link-up/link-down detection.
this by frobbing the 10TCTL register minimally, toggling only the bit we
care about (and hoping that link-capability advertisement happens correctly).
MX98715 can talk to the network now.
- Add a comment about the Macronix MX98713 -- it's almost exactly like
a 21140A, and doens't have the Nway registers that the other Macronix
chips have.
- Bus specific front-end is now responsible for reading EATA configuration
- EATA configuration data is now saved in the softc
- Make synchronous writes work properly
- Don't ignore HBA timeouts in dpt_cmd()
- Prefix eata_cfg's members with `ec_', not `dc_'

the reset path.
Hi, Jason is getting really tired of broken clone chips, and really wishes
real 21140 boards were still available, because the DEC chips seem to work
Just Dandy.
support for the ISV SROM format used in the 2114{1,1A,2,3}. Note, like
the 21040, auto-sense is not yet supported for the 21041.
Add a "pre-init" hook, which will be used for the 2114x and PNIC (currently)
which allows chip-specific code to set up and write OPMODE before the
chip is reset. This is necessary in order for the chip's internal
pathways to get initialized properly for MII/SYM/PCS/SIA media attachments.
Thanks to Dave Sainty for the hint from the `de' driver that inspired the
pre-init hook.
- Fix the SROM checksum routine.
- Add code to parse the old DEC Address ROM SROM format.
- Rearrange the statchg routines a bit, to make them consistent with one
another.
- Add support for the DECchip 21040. XXX No support for media autosense
yet, and no support for any of the multi-port boards yet.
Tree structure:
- sys/arch/sh3: sh3 generic code
As commented, in-chip device drivers are put into sys/arch/sh3/dev.
- sys/arch/evbsh3: sh3 evaluation boards (pure sh3 CPU, no fancy external HW)
- sys/arch/mmeye: Brains mmEye, www.brains.co.jp
MI source code includes couple of #ifdef for sh3-coff support.
(sh3 uses coff or elf)
Needs some more improvements, especialy in sys/arch/sh3/conf/files.sh3,
to compile the tree (due to last minute tree structure change).
Drop multicast/broadcast packet looped back from myself.
This is to cope with SMC91C92 (Megahertz XJ10BT), which
loops back multicast packet to itself on promiscuous mode.

put it in Store-and-Forward mode right from the get-go. This eliminates
the DMA underrun errors that prevented the receive filter setup from working
and caused smashed packets to go out onto the wire.
My NetGear FA310-TX board now works.
There are still "filter setup failed to complete" messages, however they
don't appear to indicate that the filter setup actually failed, since
unicast and multicast packet reception work fine. I will address this
problem shortly.
Reading the log for the FreeBSD `pn' driver suggests that these chips are,
in fact, pretty crappy, riddled with hardware bugs (for which more workarounds
are coming).
rewrite of the driver for the DECchip 21x4x Ethernet chips, and a variety
of clones.
Currently, the driver supports the Winbond 89C840F (this works pretty
well), and the Lite-On PNIC (e.g. NetGear PCI boards), however Lite-On
support may be broken [I may simply have a busted test board].
Eventually, support for the Macronix and ASIX chips will filter into
this driver, and then, slowly, support for the genuine DEC chips,
and maybe even the DE-425 EISA model.
and consider it to be like an RCC (receive copy complete). The RCC
code path has always checked for bad received packets.
- Trim the CRC length off the recived packet length; the EPIC/100 always
includes the CRC in the packet.
- Improve fatal error reporting.
- fix printing of Ultra-DMA modes (shows up when the drive supports highther
modes than the controller).
- Don't use C_NEEDDONE anymore. We were setting this flag in a possibly
freed wdc_xfer (this didn't create problems, as it was free'd in the POLL
case only, while IRQs are blocked, but it's not good practice anyway
and pool(9) complains about it ;)

the code to allocate the overrun buffer with the control blocks, and

Note that overrun_buf cannot actually be shared between all boards; DMA safe

Garbage-collect two functions which are no longer used because of the

- Set up timeout per xfer instead of per interrupt. This helps with
PIO transfer (we would call timeout()/untimout() several times for a
transfer).
- If we missed an interrupt for a PIO transfer, reset and restart it
immedialy, don't try to recover and continue. If we missed an interrupt we
may have lost a read/write cycle on the IDE bus. If this happens 1) we
corrupt data and 2) we enter an interrupt loop at the end of the xfer, as
the drive has some more data to read/write, but the host thinks the xfer is
done.
This last change fix the (or at last some of the) 'lookup after lost interrupt'
some peoples have been experiencing.
anyway, take advantage of this and greatly simplify the programming
of the multicast filter. This solves the last reported "device timeout"
problem with this driver.
to the EPIC/100 driver's (adjusting for the fact that Intel Ethernet chips
are from Pluto):
* Don't allocate receive buffers until the interface is actually brought
up, and release all of them if the interface is taken down.
* Add a knob (defaults to off) which will copy an incoming packet to
a single header mbuf if it is small enough to fit in one, rather than
burning an entire cluster on it. Note that this change will be mostly
moot if/when sbcompress() is changed to handle compressing clusters.
Simplify some of the receive list logic:
* Rather than using a homegrown queue and additional software RX descriptors,
use an ifqueue to queue receive buffers, and M_{GET,SET}CTX() to hook DMA
maps and receive buffers together.
Clean up a bit:
* Macroize a bunch of things to make the code a bit easier to follow.
* Don't allocate receive buffers until the interface is actually brought
up, and release all of them if the interface is taken down.
* Add a knob (defaults to off) which will copy an incoming packet to

Constantine Sapuntzakis confirmed by Bill Sommerfeld. Although nothing is
supposed to call wakeup on this without setting AT_DONE, it's good practice to
do it this way (the process may be waken up by a setrunnable() call).

- Don't rely on ATA signature: some ide controllers seems to not transmit it
properly (SIMIDE on arm32 machines). Instead, when we guess a drive is here
after reset, just mark it as ATA and OLD is it's not ATAPI.
- at attach time, use IDENTIFY to eliminate ghost from the probe. If the
drive had the old flag and IDENTIFY failed, issue a WDCC_RECAL command
to detect a pre-ATA disk. If IDENTIFY succeded, remove the OLD flag,
it's obviously not a pre-ATA disk.
- add a new controller flag, WDC_CAPABILITY_PREATA, used to shorcut parts
of the probe (not necessary, but makes the probe/attach faster). This is
only set by the ISA front-end, all other controllers supported can't have
pre-ATA drives attached.
The mechanism used are more or less the same as before, they have just been
reordered. Should solve port-arm32/7324 (waiting for feedback).
