Description Ivan Rozhuk 2022-08-15 23:15:16 UTC 
I have set:

rc.conf:
kld_list="${kld_list} cc_htcp tcp_rack"

sysctl.conf:
net.inet.tcp.functions_default=rack	# Use TCP stack: freebsd / rack
net.inet.tcp.cc.algorithm=htcp		# TCP cognestion algoritm


After boot all daemons started with default freebsd+newreno:
# netstat -c -C -L -n -a
Current listen queue sizes (qlen/incqlen/maxqlen)
Proto Listen                           Local Address          Stack   CC            cwin   ssthresh   MSS ECN
tcp4  0/0/128                          127.0.0.1.631           freebsd newreno 1073725440 1073725440   536 n/a
tcp6  0/0/128                          ::1.631                 freebsd newreno 1073725440 1073725440  1220 n/a
tcp4  0/0/128                          *.22                    freebsd newreno 1073725440 1073725440   536 n/a
tcp6  0/0/128                          *.22                    freebsd newreno 1073725440 1073725440  1220 n/a


This happen because boot order is:
sysctl - at this point rack+htcp can not be set, not loaded
kld
daemons
sysctl_latest

I do not want move cc_htcp and tcp_rack to loader or write some workaround script to restart all services with freebsd+newreno after boot done.
