Avoid an integer overflow on systems w/ more than 2G of RAM.
bicons_getc: calls vrkiu_getc() when vrkiu is configurated only.
add 3c905B-COMBO
regen
-support 3c905B-COMBO - somewhat preliminary: the chip has both an internal
 MII PHY capable of NWAY (according to the Linux driver) and plain BNC/
 transceiver connectors. The shared code can't handle this yet, so leave
 out MII/NWAY for now.
-print out revision number from PCI config header, this has been useful to
 identify buggy chips
Cast the argument to ptoa() to a vaddr_t to prevent an integer overflow
from occurring on systems with more than 2G of RAM.
Use ptoa() consistently when printing out how much memory we have, etc.
ndc is now a binary so we don't need the 'exec' anymore.
Backout the last change.
Romania, Socialist Republic of -> Romania, Republic of (this is correct, but
the appropriate standards should be checked anyhow (HI KLAUS!)).
Nix that, apparently the prefered form is simply `Romania'
Render LL128-safe (fixing printf formats)
don't need private `imb' inline anymore.
Quiet down the "excessive collision" messages w/ LEDEBUG.  None of the other
Ethernet drivers really report this quite as loudly as this did.
Use vertical nscheduling for bulk traffic.  It improves bulk thruput a lot.
From FreeBSD and Nick Hibma.
Attempt to document what bsd.obj.mk does.
nope, those are unsigned long longs; correct accordingly..
open(2) can legally return 0.  Errors only if return value < 0.
(Test for good is >= 0.)
Return the blocksize-rounded-up length (which was the size malloc()d
anyway).  The resultant pwrite() is now a multiple of the blocksize and
doesn't fail on a pmax with the MI SCSI driver.

Problem noticed by Tohru Nishimura.
Don't be verbose unnecessarily. (Instead, just remove this stale debug
code)
