This patch adds support for Ethernet to the Intel Galileo port. It uses the Intel Quark X1000 Ethernet driver. It initializes the first Ethernet interface and starts some common network services. By default, it uses the following addresses: - Host: 192.0.2.2 - Netmask: 255.255.255.0 - Default gateway: 192.0.2.1 - DNS server: (same as default gateway) These settings can be changed by editing eth-conf.c.
