CardBus bus stub, YENTA PCI-CardBus bridge (cbb), 3Com 3C575TX driver
(ex) and Intel fxp driver.
TODO:
o Conform to the KNF more strictly.
o Be unified with pcmcia code as much as possible.
o Add more drivers for CardBus card, such as APA-1480 or USB card.

do a gross hack which allows seemingly-broken quantum drives to function
with this driver. The gross hack is to disable tagged queueing completely
when QUEUE FULL is received. That costs performance on drives which
do tagged queueing properly and which return QUEUE FULL, but given the way
this driver works it's seems to be the only thing short of significant
recoding which will make it function with the quantum drives in question.
2. pull in a fix from FreeBSD:
revision 1.18
date: 1999/09/17 18:04:14; author: wpaul; state: Exp; lines: +3 -3
Remember to account for ETHER_ALIGN when setting the maxmimum packet
length for mini receive ring. The max length was MHLEN, however the mbufs
are actually shortened to MHLEN - ETHER_ALIGN to force payload alignment.
queueing support that decreases the number of openings on a device; it
previously assumed that a scsipi_link's `openings' were descreased as
commands were issued, which is not longer the case (`active' is increased).
- 82C115 has a 128-bit multicast hash table, not 512-bit.
- Correct the way the MAC address is read from the SROM, after re-reading
the MX98715A Application Note.
Other semi-related changes:
- Differentiate between MX98715 and MX98715A.
- Improve the Macronix link-up/link-down detection.
- 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_'
add the gross hack originally implemented by Charles Hannum in the SonicVibes
driver to force allocation of DMA memory for that channel through the Scatter-
Gather Map to get an address range that fits in.
The eso driver now works on Alphas except for DWLPX-based systems, whose owners
are not likely to desire audio or likely can afford slightly less cheap audio
hardware. :-)
ISV SROM format. For these boards, we provide the GPIO pin direction
info, a separate reset hook, and hard-wire them to MII-on-SIO.
Based on a patch submitted by Luoqi Chen <luoqi@chekov.watermarkgroup.com>.
boards which use MII for media attachment.
ISV SROM format information lifted from Matt Thomas's `de' driver.
Thanks to Dave Sainty for experimenting w/ his 21140A MII boards, and
for supplying a fix to the MII bit-bang code (PR #8382).
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.
address against our station address if it's not a multicast packet. Either
the Rhine manual lies about the phys/broadcast/multicast rxstatus bits,
or the Rhine chip is just broken.
Fixes a redirect storm problem reported by Laine Stump on current-users.
- 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.
todo:
-IPv6
-clean up jumbo buffer allocation - NetBSD provides an opaque argument
to the free function, thus doesn't need the hack done here
-deal correctly with the mapping of the shared memory
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.
chip-dependant code this required the following changes:
- Instead of attaching the device in a generic way with some chip-dependant
routines, use a chip-dependant attach routine with some common code
factored out. The code is marginally bigger, but this allows the CMD64x
flag hack to go away.
- For chips that report per-channel 'irq triggered', test this before calling
wdcintr() for the native-pci irq case (compat intr can't be shared),
as wdcintr() has no good way to know if a irq was for it or not, and
ends up with irq loss. XXX for chips that don't have this feature irq sharing
will not work properly !
- add my copyrigth notice (could have been done some time ago I think :)
There are still some issues to be solved with the Promise controller and
ATAPI devices.
Many thanks to Paul Newhouse for shipping me 2 Ultra/33 boards for doing this
work.
* 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() it changed to handle compressing clusters.
