Subject: kernel: Enable BBR as default TCP congestion algorithm
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5c8b5c3923a9b38a8f29d4f478d537868d14a295;p=people%2Fms%2Fipfire-2.x.git

kernel: Enable BBR as default TCP congestion algorithm

This will increase throughput since BBR is more modern and adjusted to
the nowadays version of the Internet whereas Cubic is more conservative
and might not always fully saturate the downlink.
