From a4618ec88de95a86f290d01c74c506552f1a5d95 Mon Sep 17 00:00:00 2001 From: Pandi Kumar Maharajan <pandi.maharajan@intel.com> Date: Thu, 18 Feb 2016 09:19:25 -0800 Subject: [PATCH] i40e: suspend scheduling during driver unload We need to suspend scheduling or any pending service task during driver unload process, so that new task will not be scheduled. This patch sets the suspend flag bit during reload which avoids service task execution.
