From: Milan Krstic Date: Sun, 20 Jan 2019 11:44:37 +0000 (+0100) Subject: ar71xx: ag71xx: preserve port mirror flags during swconfig apply X-Git-Tag: v19.07.0-rc1~1555 X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=39ede7bc67bbb54ae1645fba9f6b7a2bcc9b8c0f;p=openwrt%2Fstaging%2Fpepe2k.git 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.
