[PATCH] net: Add MOXA ART SoCs ethernet driver

[Jonas Jensen]

I think this driver may have a bug.

After some time running ping successfully, the message "no TX space
for packet" is printed resulting in 100% packet loss.

The message is printed from .ndo_start_xmit and I think it may be
because of how priv->tx_desc_now is now set up in
moxart_mac_setup_desc_ring.

I will take a look at this and try to fix the issue.

Best regards,
Jonas
