Linux BBRplus Kernel 5.14 ported from BBRplus 4.14
(note that it does NOT based on 5.14 version of BBR, instead just simple ported the 4.14 version of BBRplus)
based on original version
https://github.com/cx9208/bbrplus
net.ipv4.tcp_congestion_control = bbrplus or net.ipv4.tcp_congestion_control = bbr
(or you can use releases compiled by me in "Releases" section)
(build requirement to GCC is >= 4.9, so GCC upgrade is needed if use CentOS 7.x as builder)
(e.g., convert_official_linux-5.14.x_src_to_bbrplus.patch)
say 5.14.11
wget https://cdn.kernel.org/pub/linux/kernel/v5.x/linux-5.14.11.tar.gz
tar zxvf linux-5.14.11.tar.gz && cd linux-5.14.11
something like
cp ../convert_official_linux-5.14.x_src_to_bbrplus.patch .
patch -p1 < convert_official_linux-5.14.x_src_to_bbrplus.patch
(if no error or failed on previous step)
