==========

The device has on ethernet interface onboard, which is called *eth0*.
It supports 10/100 Mbit connections and MDI/MDI-X.
It ships with the following default network configuration:

+-------------------+----------------+
| Parameter         | Setting        |
+===================+================+
| Linux interface   | eth0           |
+-------------------+----------------+
| Connector         | J2             |
+-------------------+----------------+
| IPv4 address      | 192.168.37.250 |
+-------------------+----------------+
| IPv4 address      | 255.255.255.0  |
+-------------------+----------------+


The interface for CP [#f1]_ SLAC [#f2]_ is called *qca0*. It behaves like a usual ethernet
interface (including ethtool support). The QCA7000 which is connected via SPI to
the i.MX28 runs in burst mode. This interface ships with the following default
network configuration.

+-------------------+----------------+
| Parameter         | Setting        |
+===================+================+
| Linux interface   | qca0           |
+-------------------+----------------+
| Connector         | X6             |
+-------------------+----------------+
| IPv4 address      | 192.168.66.2   |
+-------------------+----------------+
| IPv4 address      | 255.255.255.0  |
+-------------------+----------------+

Note: In order to keep compatibility with older BSP the CP interface is renamed
during boot from eth1 to qca0.
