6270ed1711 Add the A12 fast ethernet controller, an if_de.c hacked (prior to 
bus_dma's appearance in the tree) to support sram bounce buffers.
When a busified if_de.c appears, this module can join awd.c at the
end of that long walk on a short pier.

0c2efd7025 Add a "scrollskip" member to wscons_emulfuncs (XXX even though it's not 
a function) which specifies how many lines will be skipped when scrolling
up when the bottom of the screen is reached.  Dumb framebuffers skip 10
lines (as before) because the copies are s ... l ... o ... w, but it's
silly to skip 10 lines on VGA, since the copies are much faster, so we
only skip one in that case.

37b8edbeac In addition to MAS_ABT, check TAR_ABT when doing configuration space 
reads.  This is necessary because of newer AlphaStation firmware doing
the Wrong Thing with target aborts behind PCI-PCI bridges, much like they
do the Wrong Thing with master aborts.  Reported by Matthias Drochner.

thorpej
f784e8dc15 Apparently, new AlphaStation 500/600 firmware has the same problem with 
PCI master aborts as eb164 firmware, so use the same workaround mechanism
on all system types (clear error register's master abort bit, and check
it after accessing configuration space), not just eb164's.

This also fixes a bug on eb164's - when making the Alpha port compile
again, I made an error that caused this to not be used on eb164 systems,
either.  Thanks to Matt Jacob for pointing out this goof.

23d0cae1eb It helps streaming performance substantially to enable bursts and more up hose 
packets. It's not clear whether latency will be affected much. It could be.
However, for the time being, getting full rates out of HIPPI or SCSI are what
interests us at NASA, so we'll hew to this bias.

compliation without DEBUG and/or DIAGNOSTIC happens without errors.
Note that all such initializations in the Alpha port are marked with "XXX
gcc -Wuninitialized".  As far as I'm concerned, the one or two times
-Wuninitialized has saved me from problems are worth the (very minor) cost
involved with the initializations, esp. if it's noted why the
initializations are done.  This was prompted by PR#3690, from Ted Lemon.

    pci_swiz* files are for machines whose PCI interfaces require address
    "swizzling."  Later, there will be probably be other sets, e.g. pci_bwx*
    for machines whose chipsets can easily deal with the Alpha BWX extensions
    when doing device accesses.)
