The ibmveth driver is memcpy()'ing the mac address between a variable
(register) and memory. This assumes a certain endianness of the
system, so let's make that implicit assumption work again.
This patch adds be64_to_cpu() calls to all places where the mac address
gets memcpy()'ed into a local variable.
