Network BSP setup

realtek has 8 Bit Mode.
device read_data gives the byte order correctly.

arp pkgs works well.
ip doesn't work.

I can indentify eth_type 0x800 and 0x806 well when ether_input().

More Ideas?

just my idea: has the realtek driver already been
tested with a big endian CPU (i assume the SH1 is
big endian)? Maybe some trouble lies there?
