File 0001-conntrack-tcp-fix-parsing-of-tuple-port-src-and-tupl.patch of Package conntrack-tools

From 8a251ddc8c9da5b04e95eaba23cde6ab6576b7ca Mon Sep 17 00:00:00 2001

Subject: conntrack: tcp: fix parsing of tuple-port-src and tuple-port-dst
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As seen in the parsing code above, L4PROTO should be set to IPPROTO_TCP, not the port number itself.

Fixes: 40efc1ebb15b ("conntrack: cleanup command line tool protocol extensions")
