You should implement a HardMAC level driver. Basically it is a plain networking driver (as most other Linux networking drivers are). It should pass MAC-level frames to the kernel via netif_rx() interface. You will get frames MAC-level frames from upper layers via ndo_hard_xmit() callback as usual network devices do. On top of that you will have to implement wpan_phy interface to control 802.15.4 specific behaviour of your device (see fakehard.c). serial.c driver from linux-zigbee source tree should not be of real help for you, other than study how to implement a tty line discipline. You need to implement new tty linedisc that will handle your serial protocol. > > By the way for the HardMAC implementation, I don't understand in the > fakehard.c example how are received the data and how are sent to the higher > layer? fakehard.c is a simple example that provides no real data handling. Please follow other tutorials (statrting from Linux Device Drivers book) on how to implement network drivers. You will have to set fields correctly (ARPHDR_IEEE802154, etc.). Also you will have to fill in the control block correctly for the packet to be parsed by upper 802.15.4 layers. -- With best wishes Dmitry ------------------------------------------------------------------------------ Write once.
