From 5a5c52085a5bd0b1b8bc629f3586c7a93dcb4460 Mon Sep 17 00:00:00 2001 From: Kevin Jilissen Date: Sat, 4 May 2024 16:12:20 +0200 Subject: [PATCH] realtek: Trap LLDP packets to the CPU We should setup the registers for trapping LLDP packets to the CPU. Currently, these packets are forwarded to all ports which is not desired behaviour.
