htcp not in RHEL 9

[msjang]

configure_sysctl script tries to configure tcp_congestion_control as htcp, but it is not in RHEL 9.

# uname -r
5.14.0-284.11.1.el9_2.x86_64

# cat /etc/redhat-release
Rocky Linux release 9.2 (Blue Onyx)

# sysctl -w net.ipv4.tcp_congestion_control=htcp
sysctl: setting key "net.ipv4.tcp_congestion_control": No such file or directory

# sysctl net.ipv4.tcp_available_congestion_control
net.ipv4.tcp_available_congestion_control = reno cubic bbr dctcp

@msjang Probably a bit late (I was just scrolling through the issues section within this repo).. but yeah just a side note as a fellow perfSONAR user, you can find tcp_htcp kernel module within kernel-modules-extra package on RHEL9 or Rocky9.

This should automatically load when htcp is present within net.ipv4.tcp_available_congestion_control

I'll get this added to the next feature release.

Release Notes:

Kernel modules to support additional TCP congestion control algorithms are now installed on EL systems.
