Add a sleep lock that protects access to sequences of blocking
axe_cmd() calls. Without this the device can get confused if multiple
threads attempt these operations concurrently. The problem was
easily reproducible by running "ifconfig axe0" in a loop because
eventually it would conflict with axe_tick_task().
A similar approach is probably required in all USB ethernet drivers.
