Subject: [PATCH net 0/2] tcp_metrics: fix hanlding of route options
Date: Fri, 13 Jun 2025 12:20:10 +0200 [thread overview]
Message-ID: <20250613102012.724405-1-ptesarik@suse.com> (raw)
I ran into a couple of issues while trying to tweak TCP congestion
avoidance to analyze a potential performance regression. It turns out
that overriding the parameters with ip-route(8) does not work as
expected and appears to be buggy.
Petr Tesarik (2):
tcp_metrics: set maximum cwnd from the dst entry
tcp_metrics: use ssthresh value from dst if there is no metrics
