Move this header out of the common header. Network support is used in
quite a few places but it still does not warrant blanket inclusion.

split into the driver-mode support, functions, structures, checksumming,
etc.

The SST26VF064BEUI spi-nor flash is programmed at the factory with a
globally unique address stored in the SFDP vendor parameter table and
it is permanently writeprotected. Retrieve the EUI-48 address and set it
as ethaddr env.
