- Work around a bug in the 82557 that causes the receiver to lock up
in certain conditions by kicking the multicast address filter if we
haven't heard anything come down the wire for some period of time.
- Fix a bug that could cause TxCB descriptor chains to cross page boundaries
on the Alpha.
- Remove some unneeded register masking.
- Fix a bug where too much data was copied from the config template, causing
memory corruption.
- Fix handing of if_timer (it was be cleared too early in some cases).
- Attempt to reduce the chances of receiver overrun by doubling the
number of receive DMA segments, and processing receive interrupts
before transmit interrupts.
- Remove a gratuitous assignment.
- Fix a bug where incoming packets were counted twice.

o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
Add newer Intel / VIA i386 chipsets.
Correct one S3 chip, add one.

and kern/4170 (identical).
memory-mapped or i/o-mapped access to the device registers, and always
choose memory-mapped if it is enabled. In particular, do _not_ explictly
disable the space we decide to not use, as this confuses some versions
of Alpha console software (which are arguably buggy because of this
problem).
Also, fix a logic error pointed out by Ross Harvey <ross@teraflop.com>
that would cause memory-mapped access to never be enabled.
pci_map_mem(), with appropriate changes for bus_space.
* Add extra arguments for use by pci_mapreg_*(), and make the functions
static.
* Rewrite pci_mapreg_info() and pci_mapreg_map() as wrappers around
pci_*_find(), using the documented interface.
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.
able to read SXP registers (instead of panicing). Probably have done a bit
of setup overkill- we now alloc some scratch memory for the 2100 that I thought
I would need for the Port database, but so far I haven't needed to retrieve
the port database. Well, early days yet.
call for the board's memory space to be PCI_MAPREG_MEM_TYPE_32BIT_1M or
PCI_MAPREG_MEM_TYPE_32BIT depending on the board ID. Also, remove a
bogus extra argument to an interrupt-establishment-error printf. Problems
pointed out by Jarkko Torppa <torppa@cute.fi> in PR 3753, but fixed slightly
differently than he suggested.
- Add NetBSD autoconfiguration support.
- Rearrange code slightly to minimize the number of #ifdefs.
- Don't use a structure to access CSRs. Use macros that DTRT for
the NetBSD and FreeBSD cases.
- Deal with alignment contraint on Alpha - add 2-byte padding at the
beginning of the RFA, so that the data will be 4-byte aligned, after
the 14-byte Ethernet header.
Thanks to Matthias Drochner for the testing, and David Greenman for
the feedback on the changes.
by default if it's usable, but falling back to I/O space if mem isn't usable.
If NCR_IOMAPPED is defined (default on the x86), prefer I/O space
then fall back to mem. Also, clean up the various memory consistency checks
so that they can deal with run-time determination of whether or not the
device is to be memory- or I/O-mapped.

deprecate use of pci_{io,mem}_find(), but leave them around (for a while)

arguments, so that a device can tell if its memory and I/O spaces are
enabled. The flags are cleared, depending on the contents of devices CSR
registers, in the machine-independent PCI bus code.
this code makes equal sense for memory and I/O space, prefer to map
the PCI front end via memory space (conditionalized on a patchable kernel
variable), and do a bit of other random NetBSD-specific cleanup. (These
changes were sent to Justin Gibbs on March 28.)
correspond to the ANA numbers... certainly includes ANA-5940.
- add Efficient Nets product 0x0000. according to linux pci.h
the 0x0000 is an FPGA version of the midway card and the 0x0002
is the ASIC version.
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.
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.

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)

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.
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.
