[dpdk-dev] [PATCH v2] igb_uio: issue FLR during open and release of device file

[Gregory Etelson]

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
