From: Joan Lledó <[email protected]>
Replace raw uint32_t parameters with lwIP's ip4_addr_t / ip6_addr_t so
callers don't have to cast back and forth. Drop the now-unused
addr6_prefix_len parameter from configure_device() and the addr6
parameter handling in update_if_args, and update all call sites in
iioctl-ops.c, options.c and pfinet-ops.c accordingly.
