    em(4): Enable RX after RDH is configured (backport from emx(4)).
    According to Intel OpenSDM's RDH description:
    "... If software were to write to this register while the receive
     function was enabled, the on-chip descriptor buffers can be
     invalidated and other indeterminate operations might result ..."
    Maybe we were just that lucky, the driver actually worked ...
