Subject: Re: [PATCH v2] igb_uio: issue FLR during open and release of device file
Date: Mon, 10 Jul 2017 06:07:45 +0300	[thread overview]
Message-ID: <1912538.AEa4I0QC60@polaris> (raw)
In-Reply-To: <5cf77ba2-8c29-ca31-1141-63ca01eff9f5@intel.com>

Hello Ferruh,

I could not reproduce server crash with the patch.
However, some tests report ixgbe_vf_pmd and i40e_vf_pmd 
do not receive and transmit frames after process restart,
although PMD initialization completed successfully
Is there a way to collect PF firmware dump for investigation ?

Regards,
Gregory
