With the advent of G3/CDMA modems, the old buffer sizes are no longer
adequate. Increase them to 1k. The referenced PR made this a sysctl,
but that seems like overkill to me. The difference between 320 and
2048 bytes in modern systems, even embedded ones, seems to be in the
noise to be worth the extra hair to make it settable.
