From 47eef3a5ce981c6754836c8c996b4cc724617604 Mon Sep 17 00:00:00 2001 From: Chuanhong Guo Date: Wed, 23 Jan 2019 13:46:15 +0800 Subject: [PATCH] generic: ar8216: introduce qca,mib-poll-interval property This allows users to specify a shorter mib poll interval so that the swconfig leds could behave normal with current get_port_stats() implementation.
