staging: wfx: allow to send 802.11 frames
Three things make this task more complex than it should:
- Chip necessitate to associate a link-id to each station. It is same
thing than association ID but, using 8 bits only.
- Rate policy is sent separately from Tx frames
- Driver try to handle itself power saving of stations and multicast
