+Subject: [PATCH] MIPS: Octeon: Fix DT pruning bug with pip ports
+
+During the pruning of the device tree octeon_fdt_pip_iface() is called
+for each PIP interface and every port up to the port count is removed
+from the device tree. However, the count was set to the return value of
+cvmx_helper_interface_enumerate() which doesn't actually return the
+count but just returns zero on success. This effectively removed *all*
+ports from the tree.
+
+Use cvmx_helper_ports_on_interface() instead to fix this. This
+successfully restores the 3 ports of my ERLite-3 and fixes the "kernel
+assigns random MAC addresses" issue.

+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.

+
+Add support for Octeon USB HCD. Tested on EdgeRouter Lite with USB
+mass storage.
+
+The driver has been extracted from GPL sources of EdgeRouter Lite firmware
+(based on Linux 2.6.32.13). Some minor fixes and cleanups have been done
+to make it work with 3.10-rc3.
