net: macb: Add ARP support to WOL

Browse source

Extend wake-on LAN support with an ARP packet.

Currently, if PHY supports WOL, ethtool ignores the modes supported
by MACB. This change extends the WOL modes with MACB supported modes.

Advertise wake-on LAN supported modes by default without relying on
dt node. By default, wake-on LAN will be in disabled state.
Using ethtool, users can enable/disable or choose packet types.

For wake-on LAN via ARP, ensure the IP address is assigned and
report an error otherwise.
