From 39ede7bc67bbb54ae1645fba9f6b7a2bcc9b8c0f Mon Sep 17 00:00:00 2001 From: Milan Krstic Date: Sun, 20 Jan 2019 12:44:37 +0100 Subject: [PATCH] ar71xx: 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. This fix preserves port mirroring flags during apply.
