f52393a257 Correct the definition for PN_NETCFG_NO_RXCRC: it's 0x20000000, not
0x02000000. This error was causing the chip to always include the

PN_NETCFG_NO_RXCRC, but it was frobbing the wrong bit).

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

c13be48aee Put back some missing chip identification code that got lost somehow
during a trek through RCS. The Macronix 98713 and 98713A both have the
same PCI device ID but different revision numbers, and we need to be
able to tell one from the other. The 98715 and 98715A chips have the
same device ID as the 98725 chip but different revision numbers, however
we lump them into the same category except when identifying them during
the PCI probe output.

The main reason we need tell the chips apart is that the Macronix app
notes say you have to write a special magic number into one of the
registers in order to put the chip in normal operating mode. The 98713
requires one magic value, while all the others require a different one.

726ff6a158 An early Christmas present: add driver support for a whole bunch of
PCI fast ethernet adapters, plus man pages.

if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
         various other PNIC devices

if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
         other boards based on the Macronix 98713, 98713A, 98715, 98715A
         and 98725 chips

if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
         Rhine II chips (note: the D-Link and certain other cards
         that actually use a Rhine II chip still return the PCI
         device ID of the Rhine I. I don't know why, and it doesn't
         really matter since the driver treats both chips the same
         anyway.)

if_wb.c: Trendware TE100-PCIE and various other cards based on the
         Winbond W89C840F chip (the Trendware card is identical to
         the sample boards Winbond sent me, so who knows how many
         clones there are running around)

All drivers include support for ifmedia, BPF and hardware multicast
filtering.

Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.

I also have a driver for the ASIX AX88140A in the works.

552a0ec7c3 The Accton 1207D adapter uses a chip called the MXP 5030 (or 5038)
which is either a RealTek 8139 in disguise or a RealTek workalike.
This commit fixes the PCI vendor/device ID for this device
and updates the description string to reflect the actual identity
of the device.

I also changed the transmit encapsulation routine to always to
buffer copies on transmit. We end up doing this 99% of the time
anyway. I also tweaked the code that pads packets out to the minimum
length (60) bytes. I was fixing up the m_pkthdr.len value but not
m_len. I don't think this makes that much difference in the grand
scheme of things, but it makes me feel better.

cd8ab93c90 In the cyrix Cx5530, there are null (empty) Base address registers before the
base register that controls Ultra-DMA, so we need to examine all possible
base registers instead of just giving up at the first empty one.
Also, looking at the source code to the BIOS, I see that they are also
checking for 0xffffffff as an invalid value so do the same. Stefan may like
to clean this up, but at least now I can find my PCI IDE registers.

1c403cb2b6 Modify the transmit packet queuing strategy a bit to be a little less
agressive. With the old code, if a descriptor chain was already on its
way to the chip, xl_start() would try to splice new chains onto the end
of the current chain by stopping the transmitter, modifying the tail
pointer of the current chain to point to the head of the new chain, then
restart the transmitter. The manual says you're allowed to do this and
it works, but I'm not too keen on it anymore.

The new code waits until the eixsting chain has been sent and then
queues the next waiting chain in the 'transmit ok' handler.

Performance still looks good one way or the other.

97e28a9d67 Apply patch graciously provided by Jason Wright <jason@thought.net> from
the OpenBSD group to fix a problem with the default ifmedia not being
set properly in some cases with a 3c905B, leading to a panic in ifmedia_set().

Also apply a patch to force the transmit start routine to check the
transmitter to make sure it isn't wedged if the outbound tx queue appears
full. This seems to cure some problems with 'watchdog timeout' errors
cropping up in some cases. I tried to do this before by checking for the
IFF_OACTIVE flag on entry to xl_start(), but if the IFF_OACTIVE flag is
set, ether_output() won't even call xl_start(). It should work now.

Lastly, increase the size of the TX queue from 10 descriptors to 16 to
hopefully make it less likely that the TX queue will fill up.

9460731153 Small tweak: force another reset of the adapter after probing for all the
PHYs in tl_attach(). This is mainly to suck away any possible stray
interrupts.

This prevents an intermittent problem on some systems where the adapter
probes correctly but yields a device timeout (and possible subsequent adapter
check) when configured. When I originally tested the driver, I ifconfig'ed
the interface after the system had already been booted and didn't notice
any problems, but when configuring the interface immediately at startup,
it would occasionally timeout and hang, until an adapter check interrupt
came along and reset things again. I'm not exactly sure if this is a
general problem of just something peculiar to this hardware (there are
three devices, including the tlan, all on IRQ 11) but the extra reset
shouldn't hurt anything. (It works fine with my 100Mbps Olicom adapter too.)

Thanks to Mark Taylor from Cybernet (mtaylor@cybernet.com) for allowing
me remote access to a Compaq system for debugging purposes.

b078a935b6 Overhaul the ThunderLAN driver. This update includes the following
changes:

- Cleaned up register access macros so that they work like the XL
  driver macros (you can switch from PIO to memory-mapped mode
  using a single #define -- default is still memory mapped mode).
  The old 'struct overlayed onto the memory mapped register space'
  cruft has been removed.

- Improved multicast filter code. The ThunderLAN has four entry
  perfect filter table in addition to the 64-bit hash table: we need
  one of the perfect filter entries for the station address, but we
  can use the other three for multicast filtering. We arrange to put
  the first three multicast group addresses in the perfect filter
  slots so that commonly joined groups like the all hosts group and
  the all routers group can be filtered without using up bits in the
  hash table.

  Note: in FreeBSD 3.0, multicast groups are stored in a doubly
  linked list, however new entries are added at the head of the list
  (thereby pushing existing entries down towards the tail). We want
  to update the filter starting from the oldest entry to the newest
  since the all hosts group is always joined first. This means we
  really want to start from the tail of the list, not the head, but
  to find the tail we first have to traverse the list all the way to
  the end and then add entries working backwards. This is a bit of a
  kludge and could be inefficient if the list is long.

- Cleaned up autonegotiation code: tl_autoneg() wasn't always setting
  modes correctly.

- Cleaned up ifmedia update and status routines as well.

- Added tl_hardreset() routine to initialize the internal PHY according
  to the ThunderLAN manual.

- Did away with the kludge where PHYs were treated as separate logical
  interfaces. This didn't really work, especially in the case of the
  newer Olicom 2326 adapters which use a Micro Linear ML6692 PHY which
  provides only 100Mbps support, relying on the internal PHY for 10Mbps
  support (both PHYs share the RJ45 port, with the 6692 doing all the
  autonegotiation work). This kludge resulted from my misunderstanding
  of the operation of the Compaq Netelligent Dual Port card (the tlan
  manual mentions multiple channels, but in a different context; this
  got me a little confused). The driver has been reported to work
  correctly with the dual port card.

- Added dio_getbit/dio_setbit/dio_read/dio_write functions which carefully
  set the ThunderLAN's indirectly accessed internal registers. This makes
  the EEPROM reading code more reliable.

Hopefully I won't have to touch this again before 3.0 goes out the door.
I plan to import the 2.2.x version sometime this week.

761fe626ea Really correct ncr_freeze_devq now. We scan backwards from the current
insertion point into the start queue looking for entries to remove and
mark them with the 'skip' address, recording the entry furthest from the
insertion point that needs to be removed.  We then go through a second
loop starting at the furthest entry to be removed and compress the start
queue.  The old algorithm started at (old insert point + 1) and wrapped
through the whole queue which would end up moving the start position in
the queue out from under the nose of the scrip processor.

4873663cf8 A major amount of cleaning up:
+ Change some messages about CCB memory allocation
	+ Turn a failure to DMA map all of a transaction due to lack of
	  ISP queue entries into a requeue operation (instead of the
	  case where it had been treated the same as a DMA too big
	  operation).
	+ put back splsoftvm around bus_dmamap_load calls.
	+ cleanup (and fix a glaring bug) in the and of the dma setup
	  routine. Also, the dma setup routines either return CMD_QUEUED
	  (for success) or CMD_COMPLETE (for failure) or CMD_EAGAIN
	  (for requeuing for resource shortage reasons).
