This fixes, at least, panics in ncr_attach() on i386's with about 5MB
of memory. The restriction was a hack to leave some low memory for ISA
DMA, but on i386's we now allocate pages from the top down, so all the
restriction did was cause our allocations to fail when there is no free
memory above 1MB.
events, in order to pave the way for removing a number of the ad-hoc
implementations currently in use.
Retire the at_shutdown family of functions and replace them with
new event handler lists.
Rework kern_shutdown.c to take greater advantage of the use of event
handlers.

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
int' since uintptr_t is long (64 bit) on Alpha, as are pointers.
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.

.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)
- Rewrite the transmit section to be a little less bogus.
- Set ifq_maxlen correctly. RL_TX_LIST_CNT - 1 is wrong, because for the
RealTek, RL_TX_LIST_CNT is 4. Set it to IFQ_MAXLEN instead.
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.
Found by: nosing around the PCI vendor and device code list at:

of the CRC as the multicast hash table bit, not the lower six bits. Plus
we have to flip on all bits in the table for multicast mode.

as a RealTek 8139
if_rlreg.h: use bus_space_read_X() in CSR_READ_X() macros instead of
directly calling inb()/outb() etc...
rl.4 + RELNOTES.TXT: mention that SMC EtherEZ PCI 1211-TX is supported
by the RealTek driver
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.
RealTek 8129/8139 chipset like I've been threatening. Update kernel
configs, userconfig.c, relnotes and sysinstall. No man page yet;
comming soon.
I consider this driver stable enough that I want to give it some
exposure in -current.
