From dc8142ea8906ea94a68734c1513b92b3f490fcd5 Mon Sep 17 00:00:00 2001 From: Amir Vadai Date: Thu, 25 Apr 2013 05:22:24 +0000 Subject: [PATCH] net/mlx4_en: Disable HW clock overflow check when no HW support Should not run HW clock overflow check if HW clock is not supported. Also, since this watchdog is the only customer of service_task, no need to start it in that case. Signed-off-by: Amir Vadai Signed-off-by: David S.
