From a135a9b5d9683ace787c7d86f1e642d9acfacdde Mon Sep 17 00:00:00 2001
From: Aaro Koskinen <aaro.koskinen@iki.fi>

Subject: [PATCH] MIPS: Octeon: Enable interfaces on EdgeRouter Lite
Enable interfaces on EdgeRouter Lite. Tested with cavium_octeon_defconfig
and busybox shell. DHCP & ping works with eth0, eth1 and eth2.
The board type "UBNT_E100" is taken from the sources of the vendor kernel
shipped with the product.
