From 76a629ee35d6f3b0d428acc2674fa49caddf3745 Mon Sep 17 00:00:00 2001 From: Milan Krstic Date: Mon, 21 Jan 2019 22:26:33 +0100 Subject: [PATCH] ath79: ag71xx: preserve port mirror flags during swconfig apply The swconfig load operation always triggers 'apply' function which in this driver currently clears port mirroring flags effectively undoing port mirroring configuration.
