From e689e72823e73361147849c416e5da5c4bcc8ddf Mon Sep 17 00:00:00 2001 From: Jacob Keller Date: Thu, 16 Jan 2014 02:30:06 -0800 Subject: [PATCH] ixgbevf: set the disable state when ixgbevf_qv_disable is called The ixgbevf_qv_disable function used by CONFIG_NET_RX_BUSY_POLL is broken, because it does not properly set the IXGBEVF_QV_STATE_DISABLED bit, indicating that the q_vector should be disabled (and preventing future locks from obtaining the vector). This patch corrects the issue by setting the disable state. Signed-off-by: Jacob Keller Tested-by: Phil Schmitt Signed-off-by: Aaron Brown Signed-off-by: David S.
