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.

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.


I hope you are not too frustrated now. :-)
