Hi,
you can also take a look at this work in progress of mine [0] in which I'm
implementing a driver for the Xbee s1 cards.
The implementation is still a work in progress, so it has only the basic TX
and RX operations and it includes the latest subsystem changes (at least
the version included in the 3.16 kernel).
The driver communicates with the Xbee s1 card using a serial protocol to
receive/send raw data, while most of the 802.15.4 are implemented in
hardware (for this reason its structure follows the fakehard.c driver).
well, I removed now any HardMAC functionality because it never had any
functionality. For example [0].
This was used by the fakehard driver but there was no real netlink
interface which used these calls. HardMAC driver is another topic for
the future.
this will not mean that I don't accept HardMAC drivers. I do now a
rework of this branch which looks very similar like wireless/mac80211
afterwards.
I really do understand that. Although I had some experience with
mac80211 driver, it took me a while to understand the structure of the
802154 driver. A rework is more than welcome!
The HardMAC functionality should be look like wireless. This
means a cfg802154 implementation inside driver layer. Also netdev
allocation/registration etc.. is inside driver layer. cfg802154 is just
a callback structure for the netlink 802.15.4 calls.
Really the current mainline HardMAC functionality was in some broken
state which never had any functionality.
Yes I understand. As the support for HardMAC will be defined and
included again I'll align my work and then you can evaluate it for
inclusion (in case you think can be of interest).
I hope you are not too frustrated now. :-)
No problem, I needed to write the driver anyway to run some experiments :-)
