It will give developers some cool code to write. After all, there isn't any
other reason to rewrite something if it already works.

Hello,
I'm trying to write an ethernet level network tester to test a wireless
gigabit product the company I'm working for has developed. I need
to be able to get packets off a Gig-E interface that have bad CRC
checksums so I can see how badly mangled they are. I've tried using
pcap and ng_eth

Garrett,
Can you run these tests again with rfc1323 off ?

Sender, of course -- that's the only place some of these phenomena
could possibly be observed.
Hmm, this is what has broken fast retransmit.
I should probably replace
if (tp->t_dupacks < tcprexmtthresh)
tp->t_dupacks = 0;
with
if (tcp_do_newreno && (tp->t_dupacks < tcprexmtthresh))
tp->t_dupacks = 0;
