So thats 23 knobs in the kernel for ip, another 28 for tcp, 4 for udp,
and 4 for arp.
Since udp does no backoff or e2e flow control, its hardly surprising it
doesn't have much tuning.
Since tcp does, its also hardly surprising it has at least *some*
options
To be fair, at least some of the knobs will come from IETF driven
tweaks. if 9 doesn't let you frob with them, that doesn't have to be
good. (moving from cable to wifi and VPN I sometimes want to at least
alter my MTU and frag behaviour. pMTU is broken for a lot of places and
tunnelling hurts with fragments)
