The Ethernet Controller automatically ignores packets with
alien MAC addresses, thus the CPU will not notice this traffic.
Except a few ones which are broadcasted, but probably your
environment will not create many of them. Thus a switch is
not required.

Two options:

1. Handle the complete HTTP traffic yourself.
2. Use the CGI interface.
