# 20230204 bkw: This patch allows wmnet to correctly display rates
# up to 999 terabytes/sec. Some day it too will be obsolete... I
# considered changing the lowercase "b" (for bytes) to a capital B, to
# match modern usage... but at the tiny font size wmnet uses, B looks
# too much like the number 8.
patch -p1 < $CWD/ludicrous_speed.diff

# 20230204 bkw: Disable archaic methods of getting network status.
# ipchains went away in Linux 2.6 (2003), ipfwadm has been gone since
# Linux 2.2 (1999). Also, the PPP method is no longer needed, even if
# someone's still using PPP in 2023 (generic "devstats" driver handles
# it fine). Doing this makes the executable ~10% smaller.
