From 4dde0d72ccec500c60c798e036b852e013d6e124 Mon Sep 17 00:00:00 2001 From: "Matthieu Baerts (NGI0)" Date: Sat, 27 Jul 2024 12:01:26 +0200 Subject: mptcp: mib: count MPJ with backup flag Without such counters, it is difficult to easily debug issues with MPJ not having the backup flags on production servers. This is not strictly a fix, but it eases to validate the following patches without requiring to take packet traces, to query ongoing connections with Netlink with admin permissions, or to guess by looking at the behaviour of the packet scheduler. Also, the modification is self contained, isolated, well controlled, and the increments are done just after others, there from the beginning. It looks then safe, and helpful to backport this.
