Register and initialize a new UWB device
Did you call uwb_dev_init() on it?
: is the parent radio controller who has the link to the device. When registering the UWB device that is a UWB Radio Controller, we point back to it.
If registering the device that is part of a radio, caller has set rc->uwb_dev->dev. Otherwise it is to be left NULL–a new one will be allocated.

Iterate over the list of UWB devices, calling a on each

A device went off the air, clean up after it!
This is called by the UWB Daemon (through the beacon purge function uwb_bcn_cache_purge) when it is detected that a device has been in radio silence for a while.
If this device is actually a local radio controller we don't need to go through the offair process, as it is not registered as that.
NOTE: uwb_bcn_cache.mutex is held!
| void uwbd_dev_onair | ( | struct uwb_rc * | rc, |
| struct uwb_beca_e * | bce | ||
| ) |
A device went on the air, start it up!
This is called by the UWB Daemon when it is detected that a device has popped up in the radio range of the radio controller.
It will just create the freaking device, register the beacon and stuff and yatla, done.
NOTE: uwb_beca.mutex is held, bce->mutex is held
