From e3411e326fa48c9be09ba449330352ba698db698 Mon Sep 17 00:00:00 2001 From: Petr Machata Date: Tue, 17 Jun 2025 00:44:09 +0200 Subject: net: ipv4: Add a flags argument to iptunnel_xmit(), udp_tunnel_xmit_skb() iptunnel_xmit() erases the contents of the SKB control block. In order to be able to set particular IPCB flags on the SKB, add a corresponding parameter, and propagate it to udp_tunnel_xmit_skb() as well. In one of the following patches, VXLAN driver will use this facility to mark packets as subject to IP multicast routing.
