> +ENETFEC Ethernet driver is traditional DPDK PMD driver running in the
> +userspace.'fec-uio' is the kernel driver. The MAC and PHY are the
> +hardware blocks. ENETFEC PMD uses standard UIO interface to access
> +kernel for PHY initialisation and for mapping the allocated memory of
> +register & buffer descriptor with DPDK which gives access to
> +non-cacheable memory for buffer descriptor. net_enetfec is logical
> +Ethernet interface, created by ENETFEC driver.
> +
> +- ENETFEC driver registers the device in virtual device driver.
> +- RTE framework scans and will invoke the probe function of ENETFEC driver.
> +- The probe function will set the basic device registers and also setups BD
> rings.
> +- On packet Rx the respective BD Ring status bit is set which is then
> +used for
> + packet processing.
> +- Then Tx is done first followed by Rx via logical interfaces.
