* Name: netdev_pktradio_addrlen

|
|
* Description:
|
|
* Returns the size of the node address associated with a packet radio.
|
|
* This is probably CONFIG_PKTRADIO_ADDRLEN but we cannot be sure in the
|
|
* case that there are multiple packet radios. In that case, we have to
|
|
* query the radio for its address length.
|
|
*
|
|
* Input Parameters:
|
|
* dev - A reference to the device of interest
|
|
*
|
|
* Returned Value:
|
|
* The size of the MAC address associated with this radio
