few changes:
- there was a bug in rl_list_tx_init(): it was calculating the registers
to initialize incorrectly. Not a problem on the x86 where unaligned
access are allowed, but a problem on the alpha.
- set rl_btag accordingly depending on the machine type
- rl_rxeof() needs to be sure to longword-align the packet data. This
is a little tricky since we copy the data out of the receive buffer
using m_devget(), however there's no way to tell m_devget() to fill
in the mbufs starting at a particular offset. To get around this,
we tell m_devget to copy bytes+2 bytes starting at offset offset-2. This
results in the proper alignment, and we can trim off the two leading
bytes afterwards with m_adj(). We also allocate some extra space before
the start of the receive buffer so that we don't get into trouble in
the case where offset == 0.
- redefine vtophys() in if_rlreg.h for the alpha.
Making this chipset work on the alpha is sort of the inverse of putting
a jet engine on a rowboat (putting a propeller on a 747?) but when
you can get these things for $5 a pop, it's hard to stop people from
buying them.

in the transmit code: the TX descriptor ring, and a 'shadow' ring of mbuf
pointers, one for each TX descriptor. When transmitting a packet that
consists of several fragments in an mbuf chain, we link each fragment
to a descriptor in the TX ring, but we only save a pointer to the mbuf
chain. This pointer is saved in the shadow ring entry which corresponds
to the first fragment in the packet. Later, ti_txeof() can release the
whole chain with a single m_freem() call. (We need the second ring to
keep track of the virtual addresses of the mbuf chains.)
The problem with this is that the Tigon isn't actually through with the
mbuf chain until it reaches the last fragment (which has the TI_BDFLAG_END
bit set), however the current scheme releases the mbuf chain as soon as
the first fragment is consumed. This is wrong, since the mbufs can then
be yanked out from under the Tigon and modified before the other fragments
can be transmitted.
The fix is to make a one line change to ti_encap() so that it saves the
mbuf chain pointer in the shadow ring entry that corresponds to the last
fragment in TX ring instead of the first. This prevents the mbufs from
being released until the last fragment is transmitted.

ADMtek AL981 "Comet" chipset. The AL981 is yet another DEC tulip clone,
except with simpler receive filter options. The AL981 has a built-in
transceiver, power management support, wake on LAN and flow control.
This chip performs extremely well; it's on par with the ASIX chipset
in terms of speed, which is pretty good (it can do 11.5MB/sec with TCP
easily).
I would have committed this driver sooner, except I ran into one problem
with the AL981 that required a workaround. When the chip is transmitting
at full speed, it will sometimes wedge if you queue a series of packets
that wrap from the end of the transmit descriptor list back to the
beginning. I can't explain why this happens, and none of the other tulip
clones behave this way. The workaround this is to just watch for the end
of the transmit ring and make sure that al_start() breaks out of its
packet queuing loop and waiting until the current batch of transmissions
completes before wrapping back to the start of the ring. Fortunately, this
does not significantly impact transmit performance.
This is one of those things that takes weeks of analysis just to come

- The tags commands allows users to view the number of tagged
openings for a device as well as a number of other related

- The negotiate command allows users to enable and disable
disconnection and tagged queueing, set sync rates, offsets
and bus width. Note that not all of those features are
available for all controllers. Only the adv, ahc, and ncr
drivers fully support all of the features at this point.
Some cards do not allow the setting of sync rates, offsets and
the like, and some of the drivers don't have any facilities to
do so. Some drivers, like the adw driver, only support enabling
or disabling sync negotiation, but do not support setting sync
rates.

- Dynamically set the cache alignment, and set burst size the same as

- Enable 'store and forward' mode by default. This is the slowest option
and it does reduce 100Mbps performance somewhat, but it's the most
reliable setting I can find. I'm more interested in having the driver
work reliably than trying to squeeze the best performance out of it.
The reason I'm doing this is that on *some* systems you may see a lot
of transmit underruns (which I can't explain: these are *fast* test
systems) and these errors seem to cause unusual and decidedly
non-tulip-like behavior. In normal 10Mbps mode, performance is fine

- It turns out that the 'promiscuous mode' bug what I discovered with the
PNIC is not restricted to promiscuous mode. I've been doing some remote
debugging for someone with a P75 system, and at 100Mbps, the receiver
screws up even when the NIC is in normal mode. Thus, enable the workaround
for this bug all the time. Note that the workaround is still not enabled
for the PNIC II, since I haven't tested one yet.
- Set the 'arbitration' bit in the bus configuration register and set the
maximum burst size to 16 longwords. This seems to fix problems with
transmit corruption on the P75 system mentioned above. (It probably hurts
performance a bit too, but I've given up trying to make the PNIC perform
well.)

- When trying to map ports, if mapping TL_PCI_LOIO or TL_PCI_LOMEM fails,
try mapping the other one. Apparently, some ThunderLAN parts swap these
two registers while others don't.
- Add support for bitrate (non-MII) PHYs. If no MII-based PHY is found,
program the chip for bitrate mode. This is required for the TNETE110
part, which doesn't have MII support. (It's also obsolete, but there
are still some people out there who have them.) With this change and the
change above, the Compaq Netflex-3/P 10baseT/BNC board works correctly.
(Thanks to Matthew Dodd for getting me one of these cards.)
- Convert to bus_space_foo() for register accesses.
- Add changes to support FreeBSD/Alpha. I still have to actually test
this in my Alpha box so I'm not going to update /sys/alpha/conf/GENERIC
yet.

This code includes lots of stuff for verbose probing. I'm not 100%
sure that the output of the verbose probe is correct, but everything
else works fine, and -CURRENT was broken for the 5591 before, so I'm
committing it anyway.

Note: the PNIC ignores the lower few bits of the RX buffer DMA address,
which means we have to add yet another kludge to make it happy. Since
we can't offset the packet data, we copy the first few bytes of the
received data into a separate mbuf with proper alignment. This puts
the IP header where it needs to be to prevent unaligned accesses.
Also modified the PNIC driver to use a non-interrupt driven TX
strategy. This improves performance somewhat on x86/SMP systems where
interrupt delivery doesn't seem to be as fast with an SMP kernel as
with a UP kernel.

chip int. and ext. clock synchronisation). Fixed workaround for
transmit threshold underrun. Added volatile keyword to CSR_READ_* and
CSR_WRITE_* macroses. Added DELAYs to eliminate randomness caused
by processor speed. Fixed all TXCON and RXCON registers to be accessed
only when chip is idle, as manual told. Changed epic_init_phy to
drop link by isolating and going loopback, should should force link
partner to restart autonegotiation.

a wierd double-queue arrangement.. It always empties the if_snd queue
then puts the transmit packets into a different queue that is limited
by the number of TX descriptors and does it's own discards...
This should stop the boot-time XXX warning anyway.
The i++ loop from 1..1000 is too small on very fast machines like
PII 450 MHz. Increasing the loop from 1..100000 lets the machine
access PHY. After this patch it's possible to use a SMC PCI card
on a HP Kayak XA series PC Workstation. Workaround until this fix
was to enable debugging in the driver (#define EPIC_DEBUG 1).
Without that patch you get an undefined state:
while true
do
ifconfig -a | grep status:
done
The status messages flaps between twwo values, but not
"connected".

Addtron appear to have their own VIA Rhine II and RealTek 8139 boards
with custom PCI vendor and device IDs. This commit updates the PCI
vendor and device lists in the vr and rl drivers so that we can probe
the additional devices.

AX88140A with power management and magic packet support. Correct the
addresses of the PCI power management registers and add some code to
detect the revision ID of the AX88141 and identify it in the probe
messages.
No other changes are needed since the AX88141 is functionally
identical to the AX88140A.
Now should be able to report speed for cards using NatSemi PHY.
(if you have one please let me know if it works as I
only have the Intel version)

3c905B, the RX and TX reset commands also reset the cyclone chip's internal
PHY, which causes it to restart its autonegotiation session. This takes a
second or two to complete, which makes the interface seem to stop responding
for a few seconds every time you do something that reinitializes it.
Issuing the RX and TX resets on the older 3c905 boomerang adapters doesn't
cause any delay because the boomerang chip requires an external PHY.
This should fix the problem where people doing network installs via 3c905B
cards experience a delay after the interface is first initialized, among
other things.
