From d4649942ad72a1b1db2595ace3620c1059fa3464 Mon Sep 17 00:00:00 2001 From: Birger Koblitz Date: Sat, 1 May 2021 11:22:05 +0200 Subject: [PATCH] realtek: Add SoC-specific VLAN setup routine This adds SoC specific VLAN configuration routines, which alsoe sets up the portmask table entries that are referred to in the vlan profiles registers for unknown multicast flooding.
