to the maximum allowed window. Growing the window too large would cause
an underflow in the calculations in tcp_output() to decide if a window
update should be sent which would prevent the persist timer from being
started if data was pending and the other end of the connection advertised
an initial window size of 0.

in the RX path when doing 11n and block-ack'ed frames. Apparently, the MAC
will loop over that self-linked descriptor and treat it as "good enough"
for (incorrectly!) ACKing the frames in the block-ack.
Until I figure out how to work around this issue in the future, this counter
will tell me if packet RX processing ever gets to the point where it's
touching the self-linked descriptor. If there's ever enough packets to get
to that point, BA's will be invalid and likely very unhappy.

engine is stopped so using a common function to handle the job is
better than duplicating the code.

makes controller to receive bad frames and i82557 will also receive
bad frames since fxp(4) have to receive VLAN oversized frames. If
fxp(4) encounter DMA overrun error, the received frame size would
be 0 so the actual frame size after checksum field extraction the
length would be negative(-2). Due to signed/unsigned comparison
used in driver, frame length check did not work for DMA overrun
frames. Correct this by casting it to int.
While I'm here explicitly check DMA overrun error and discard the
frame regardless of result of received frame length check.

instead of 0x100000. As a side effect, an amd64 kernel now loads at
physical address 0x200000 instead of 0x100000. This is probably for the
best because it avoids the use of a 2MB page mapping for the first 1MB of
the kernel that also spans the fixed MTRRs. However, getmemsize() still
thinks that the kernel loads at 0x100000, and so the physical memory between
0x100000 and 0x200000 is lost. Fix this problem by replacing the hard-wired
constant in getmemsize() by a symbol "kernphys" that is defined by the
linker script.
