From 7e937dcf96d0489b3cdd1cff9dfd049617d28492 Mon Sep 17 00:00:00 2001 From: Beniamino Galvani Date: Fri, 20 Oct 2023 13:55:26 +0200 Subject: [PATCH] ipv6: remove "proto" argument from udp_tunnel6_dst_lookup() The function is now UDP-specific, the protocol is always IPPROTO_UDP. This is similar to what already done for IPv4 in commit 78f3655adcb5 ("ipv4: remove "proto" argument from udp_tunnel_dst_lookup()").
