between a bug in the receive path (buffer length used instead of actual
received frame length) and the ARP code not correctly setting the length
of the reused mbuf, which all told caused the transmit logic in the chip
to wedge.
Also, make sure to count received packets.

be called. it'd cleanup() then exit(). however, cleanup() is scheduled
to run at exit via atexit(). This means that it gets run twice, and
this causes confusion for things like endwin(). The end result is
that rather than actually exiting and printing the "sysinst terminated"
message, after one control-c it looks like it's still sitting at the
last screen you were viewing even though it's actually at a shell prompt.
squelch the cleanup() in the SIGINTR handler to avoid this problem.
* while here, nuke the annoying space before the "sysinst terminated."

Use SIGBUS iff we get a legitimate bus fault. Use SIGSEGV for page protection
violations (per Solaris, SVR4, AIX, Linux, Irix, and SunOS).
...which happens to eliminate an unsafe call to uvm_map_checkprot().
starts running can occur on both DMA in and DMA out. I missed the little comment
in the Mach driver for the DMA out case. Also, only ignore the interrupt if the
TC is non-zero (to match the Mach driver).
- rather than treating MAP_COPY like MAP_PRIVATE by sheer virtue of it not
being MAP_SHARED, actually convert the MAP_COPY flag into MAP_PRIVATE.
- return EINVAL if MAP_SHARED and MAP_PRIVATE are both included in flags.
which use uvm_vslock() should now test the return value. If it's not
KERN_SUCCESS, wiring the pages failed, so the operation which is using
uvm_vslock() should error out.
XXX We currently just EFAULT a failed uvm_vslock(). We may want to do
more about translating error codes in the future.
Don't (ab)use uvm_map_pageable() to allocate PT pages. Instead, do
some internal reference counting on PT pages. We still allocate them
with the page fault routine (a wire-fault, now), but no longer free
PT pages from pmap_pageable().
Anyway, just because a drive doesn't support the LOAD (to BOT) command does
not mean that the drive doesn't support the UNLOAD command. Also note and
print errors in rewinds and unloads (and errors in writing closing filemarks
for same).
allocation strategy no longer works at all. Move pmap.new.* to pmap.*.
