From e06362369ae1e5b0ba70b66f8703ff08bcb63b23 Mon Sep 17 00:00:00 2001 From: Chun-Hao Lin Date: Fri, 29 Jul 2016 16:37:55 +0800 Subject: [PATCH] r8169: add checking driver's runtime pm status in rtl8169_get_ethtool_stats() Not to call rtl8169_update_counters() to dump tally counter when driver is in runtime suspend state. Calling rtl8169_update_counters() in runtime suspend state will produce warning message "rtl_counters_cond == 1 (loop: 1000, delay: 10)". Signed-off-by: Chunhao Lin Signed-off-by: David S.
