Log:
  - Do not reinitialize the card if it is already running.
    This fixes bootp on if_smc, as bootp code perform SIOCSIFADDR
    ioctl call immediately after sending the request (which causes
    if_init being called) which causes the adapter to drop all the
    packets received in the meantime.
