net: ethernet: sun4i-emac: Allow to enable netif messages

Browse source

sun4i-emac has the ability to print a number of diagnostic messages using
dev_dbg depending on message level settings implemented using netif_msg_*
macros. But there's no way to actually enable them.

Add the ability to switch diagnostic messages on using either a module
parameter debug or ethtool -s <netif> msglvl <flags>.
