From d08093b8b3370b67b68420af2c68e0c298e10de3 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Tue, 8 Jun 2010 20:18:34 +0000 Subject: [PATCH] ip17xx: Maintain state->remove_tag incrementally So far, state->remove_tag was sometimes updated incrementally, sometimes left to correct_vlan_state() to recalculate. Since I want to avoid use of correct_vlan_state() for IP175D, this patch fixes the only two remaining places which leave state->remove_tag inconsistent with state->add_tag and it drops the recalculation.
