This was previously implemented by adding additional members to the mp_obj_type_t defined for each NIC, which is difficult to do cleanly with the new object type slots mechanism. The way this works is also not supported on GCC 8.x and below. Instead replace it with the type protocol, which is a much simpler way of achieving the same thing. This affects the WizNet (in non-LWIP mode) and Nina NIC drivers. This work was funded through GitHub Sponsors. Signed-off-by: Jim Mussared <jim.mussared@gmail.com>
