> Subject: [PATCH v2] igb_uio: issue FLR during open and release of device file
> 
> Set UIO info device file operations open and release. Call pci reset
> function inside open and release to clear device state at start and end.
> Copied this behaviour from vfio_pci kernel module code. With this patch,
> it is not mandatory to issue FLR by PMD's during init and close.
> 
> Bus master enable and disable are added in open and release respectively
> to take care of device DMA.
