From 5be6e044bea648cc0cc083899c72252f7f2227fd Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Tue, 28 Jul 2026 18:30:43 +0200 Subject: [PATCH] net: dsa: stop at the user device in .fill_forward_path The flowtable path discovery stops at the DSA user device when setting up the forward path. Let's just report there is no more devices after the DSA user port through the .fill_forward_path interface. No functional changes are intended.
