or am I missing something?
See attached file below.
route add -sendpipe -recvpipe works on FreeBSD 4.x, but not on 6-STABLE
(or on 5.4 either - although that's not shown).
I'm trying to set the parameters for specific routes so that I can
properly account for the bw delay product. (I don't want to do it for
every connection using the global sysctls because these servers can have
many concurrent connections).
Am I doing something wrong? Or is this a bug?
If it's a bug, I'll file a PR.
