+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.
