- Deal with devices that ignore the length specified in the
inquiry command.
- Allow asynchronous requests without using a buf (key off NOSLEEP instead).
Thanks to Michael Smith for reporting, Jason Thorpe for pointing to the
report, doing a quick workaround which pointed me to the right code part and
for testing the final fix.
does not supply media types, default to the "manual" type.
- Clean up the ETHER_CMP stuff slightly.
- Keep track of our carrier status, for media status requests.
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.
the base address. This allows for a more flexible layout of buffers
in the Lance's memory.
- Add a new element 'sc_saved_csr0' to am7990_softc. It's value is or-ed
with the current csr0 value in the am7990_intr() function. This allowes
for a 'deferred' interrupt sceme.
- Implement a simple quirks framework for changers.
- Add a quirk for the Spectra 9000 8mm tape library; it requires a
slightly-longer-than-1-minute delay to take tape inventory. Many
thanks to David Webster at Cygnus Solutions for testing this for me.
to prepare for if_media, and to support EISA 3c59x cards:
* change epconfig() to take a short that encodes the chipset
type (3c509, or Demon/Vortex/Boomerang).
* add distinct 3c509 and Demon/Vortex/Boomerang media-sense
functions to back end.
* Add EISA match/attach support for the 3c592 and 3c597
(Demon) cards as well as the 3c509-comatibl EISA 3c509/3c579.
* Assume that ISA and ISA PnP cards are 3c509-style, until
proof to the contrary (e.g. large packet support).
Tested on 3c595, 3c590, and 3c509b. Not tested on 3c515 or Demon.
(RX_RESET, TX_RESET, GLOBAL_RESET).
Commands issued while a reset is in progress may be dropped. The driver
must wait until resets are complete; ep_complete_cmd() does so.
* Change RX_RESET, TX_RESET, GLOBAL_RESET to use ep_complete_cmd().
* Revert epconfig() to use inline RX_RESET, TX_RESET.
That avoids accidentally setting IFF_UP, which breaks both diskless boot,
and "halt" commands issued before the interface is brought up.

some "DECstation 5000 Model 240 Options and Upgrades" guides found
while cleaning out my office.
- Keep a freelist of component buffer headers, defaulting
to 8 headers per component (tunable with the CCDNBUF
kernel compile option).
- When allocating a component buffer, try to pull a header
off the freelist first, falling back on MALLOC() if the
freelist is empty. Use MALLOC() rather than malloc(),
because it will attempt to short-cut the allocation before
actually making a full-blown malloc() call.
- Keep statistics on how many component buffer headers have
been allocated and how many of those allocations have
resulted in freelist misses.
With these changes, I observed measurable decreases in system and
wall clock time on operations on an 8G ccd, as well as a measurable
drop in the time spent in ccdbuffer() (measured with kernel profiling).
isascan (__BROKEN_INDIRECT_CONFIG), and attempt multiple match/attach
of cloning devices in isasearch(). (If a match/attach succeeds for
a cloning device, try it again.)
- fix the parser so that non-compliant isapnp devices work, and we
give up when there are too many errors (some on-board pnp sound/atapi/game
soundblaster compatible card). reported by chuck cranor
- fix the parser so that configuration tags that come after the
end-dependencies tag or before the begin-dependencies tag are merged
in properly (gravis ultrasound). reported by gary duzan
We now build a tree of card -> logical-dev -> conf, and in the end we
convert it to a list of conf...
- if aal5 frame has a CRC error then the length field in the aal5 trailer
may not be valid, so we can not use it [and we must dump the frame]

Tested on alpha by cgd, tested on several i386 boxes. Certainly causes
no harm to the goddamned mess, but the NCR driver only works when you
perform voodoo rituals on it anyway.
This is what Dave said (in email) has been added to the driver:
----------------------------------------------------------------------
This seems to be the most significant change:
General cleanup and new features for 53c875 based cards, especially the
Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
is built with option NCR_TEKRAM_EEPROM.
Other changes:
- add brackets to expansion of OUTB/W/L macro arguments.
- remove unused NCB structure element ns_async
- support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
- correctly identify 53c810A and 53c825A chips
- preserve SCSI BIOS settings of PCI performance options
- remove (already disabled) support for NCR reset because of command timeout
- reverse order of reading of SCSI and DMA specific interrupt cause registers
- add definition of Tekram config EEPROM contents (not currently used)
----------------------------------------------------------------------
Newer boards (e.g., Vortex) take time to reset, and wedge on some machines.
Polling on S_COMMAND_IN_PROGRESS would be better, but that doesn't
work with xx_RESET commands on 3c509s.
CONFIG_CNTRL bits by making the "conn" argument to epconfig()
a u_int, not a u_int16_t, and by defining 100mbit media
bits in the upper 16 bits.
A redesigned interface that fixes this properly is in the pipeline.
comments in pr port-i386/2358: "if_ep/3C590 no longer working"
* Only call Vortex media-config code on PCI-attached devices, until
we know if it works on ISA and EISA large-packet devices also.
* Fix typo in printf of MAC address
rather than unknown.
* Look for 100mbit interfaces, and for any present, set corresponding
bits in `conn' argument to epconfig(). epconfig() will now print
100Mbit media by name.
look for 100mbit Xcvrs, print their names, add to ep_connectors.
* Print 10baseT as 10baseT, since media name (utp) is no longer a unique
transceiver type.
* Redo FIFO memory size printing, also show Tx/Rx split (xxx isa 3c509?).
* Print MAC address on a separate line, with 100Mbit media and fifo-ram
info it no longer fits on the same line as media types.
* Comment the fact that the "connection" media-selection code just doesn't
grok 100Mbit media.
* add code to look for 3c59x/3c90x media-select and autoconfig bits, though
we don't yet dynamically probe media when the autoconfig bit is set
(see previous bullet).
* XXX the whole connector/media code should be redone, perhaps a' la
the BSDI ifmedia design.
For now, we really only need 8 bits of media type.
* Add bogus definitions for 100mbit transcievers, to be set in the
"conn" argument to ep_config(). Should really use the same bits
as in EP_W0_CONFIG_CTRL bits, but I don't know what bits the 3c515
&c use for 100mbit media.
* Define bitflags for 100Mbit transceiver options in ep_connectors.
* Add definitions of powerup/powerdown commands. for interfaces with
power management. Should send a powerup after APM resume?
* Add definition of fragment-busmaster (vortex) START_DMA command.
* Add definition of PCI configuration-space media-present bits.
(really just EP_W3_RESET_OPTIONS remapped into pci config space.)
* Add comments describing what the #define's above are used for.

bit from the extended setup inquiry and key off it to:
- Force synchronous negotiation on targs > 7.
- Read additional information returned by wide cards on inquire setup.
- Read sync period on targs > 7.
- Display sync period/offset on targs > 7.
- Set scsi_link.max_target to 15.

host adapter drivers, indicating the highest SCSI target they can
address. Use this value to dynamically allocate data structures, rather
than hard-coding 8 targets.
These changes allow targets > 7 to be addressed on wide SCSI busses.
Fixes PRs #1674 and #2892.
Add newline to `Interface disabled' printf and clean up formatting.
Change packet read/write code to align all reads and writes into
memory to an appropriate boundary for the I/O size. This also fixes
a bug where the trailing unaligned bytes (1-3 of them) would be
put in an additional mbuf even if there was enough space for them
in the one we were currently filling.
This has been tested on a 3c905 in an Alpha (32-bit I/O, alignment
required), a 3c905 in an i386 (32-bit I/O, alignment not required)
and a 3c509 in an i386 (16-bit I/O, alignment not required). It
should be tested on a 3c509 in an Alpha with an ISA bus, if somone
can manage to get the two items together.
There are still some bugs in the driver relating to initialisation;
on my Alpha with a 3c905 you need to do an `ifconfig ep0 down;
ifconfig ep0 up' after the initial ifconfig to make it start working.
Apparently there are also some problems with a 3c579 in an i386,
although a 3c905 in an i386 works just fine.
