enforce payload alignment, and turn it on on the x86 as well as alpha
since it helps with NFS which wants the payload to be longword aligned
even though the hardware doesn't require it.
This fixes a problem with the ti driver causing an unaligned access trap
on the Alpha due to m_adj() sometimes not setting the alignment correctly
because of incomplete mbuf initialization.

stop for 5 seconds when the MII autoprobe is triggered in the xl and

no change is required there.)

gigabit ethernet adapters. This includes two single port cards
(single mode and multimode fiber) and two dual port cards (also single
mode and multimode fiber). SysKonnect is currently the only
vendor with a dual port gigabit ethernet NIC.
The ports on dual port adapters are treated as separate network
interfaces. Thus, if you have an SK-9844 dual port SX card, you
should have both sk0 and sk1 interfaces attached. Dual port cards
are implemented using two XMAC II chips connected to a single
SysKonnect GEnesis controller. Hence, dual port cards are really
one PCI device, as opposed to two separate PCI devices connected
through a PCI to PCI bridge. Note that SysKonnect's drivers use
the two ports for failover purposes rather that as two separate
interfaces, plus they don't support jumbo frames. This applies to
their Linux driver too. :)
Support is provided for hardware multicast filtering, BPF and
jumbo frames. The SysKonnect cards support TCP checksum offload
however this feature is not currently enabled (hopefully it will
be once we get checksum offload support).
There are still a few things that need to be implemeted, like
the ability to communicate with the on-board LM80 voltage/temperature
monitor, but I wanted to get the driver under CVS control and into
-current so people could bang on it.
A big thanks for SysKonnect for making all their programming info
for these cards (and for their FDDI and token ring cards) available
without NDA (see www.syskonnect.com).
clears out the transmit queue and zeroes the downlist pointer register,
but xl_txeof() isn't called before xl_start() tries to queue more packets,
xl_start() will think that the DMA is still in progress and not update
the downlist register again, thus causing packets to sit in the transmit
queue forever.

compiles cleanly on the Alpha. (On the alpha, the port type is an int,
not a short).
Cast a couple of pointers to ints via 'uintptr_t' rather than 'unsigned

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.
positively not let ti_encap() fill up the TX ring all the way and wrap

it set to 'Yes.' This is wrong for FreeBSD (and LoseNT): it should be set
to 'No.' Apparently it's still possible to map the iobase of the NIC and
have the card work by reading the config space manually (which is what
the driver does if pci_map_port() fails) but we need to warn the user to
do fix their machine anyway. Anyway, warn the user to check the 'Plug &

the PNIC II was jointly developed by Lite-On and Macronis. I get the
feeling Macronix did most of the work. (The datasheet has the Macronix

for the extra wake on LAN registers.) In any case, the PNIC II works just
fine with the Macronix driver.
The changes are:
- Move PCI ID for the PNIC II from the pn driver to the mx driver.
- Mention PNIC II support in mx.4.
- Mention PNIC II support in RELNOTES.TXT and HARDWARE.TXT.

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
up with two or three lines of code changes.
The specific intent of this commit is to pave the way for importing
Compaq XP1000 support. These changes should not affect the i386 port.
