Subject: RE: [net-next 17/18] net: mac802154: Let drivers provide their own
 beacons implementation

Hi Alexander,

At Qorvo, we have developped a SoftMAC driver for our DW3000 chip that will benefit such API.

To be short, beacon sending is controller by our driver to be synchronized chip clock or delayed until 
other operation in progress (a ranging for example).

Regards,
David Girault

Can you name a SoftMAC transceiver which provides such an "offload" feature?
