From deba38f2a7ee7daea08905b6d45412c1469d7c84 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Sun, 30 Mar 2014 09:15:16 +0000 Subject: [PATCH] kernel: rtl8306: fix vlan support on lantiq ar9 p2601hnfx If the CPU port is not forced up, the link, at least on this board, is lost after changes are applied. This makes sure that the link is restored. Regression tests should confirm it doesn't break other boards.
