TCP Congestion Control

[vm finance]

Hi,

We can set per-socket congestion control under Linux, but not under FreeBSD
(12.0).
The current available and allowed is only newReno:
net.inet.tcp.cc.available: newreno
net.inet.tcp.cc.algorithm: newreno

Any thoughts on why FreeBSD chose not to allow different cc to be set per
socket?
AFAIK, it would get complicated to have different sessions having different
congestion algos.

Thanks for any pointers!
