Subject: [dpdk-dev] [PATCH] ixgbe: Fix disable interrupt twice
Date: Fri, 29 Jan 2016 13:51:40 +0800 [thread overview]
Message-ID: <1454046700-20843-1-git-send-email-michael.qiu@intel.com> (raw)
Currently, ixgbe vf and pf will disable interrupte twice in
stop stage and uninit stage. It will cause an error:
testpmd> quit
Shutting down port 0...
Stopping ports...
Done
Closing ports...
EAL: Error disabling MSI-X interrupts for fd 26
Done
Becasue the interrupt already been disabled in stop stage.
Since it is enabled in init stage, better remove from
stop stage.
Fixes: 0eb609239efd ("ixgbe: enable Rx queue interrupts for PF and VF")
