2008-12-23uwb: remove beacon cache entry after calling uwb_notify()Stefano Panella
Removing the beacon cache entry from a uwb_dev can cause an oops if the bce is released before the call to uwb_notify(). Signed-off-by: Stefano Panella <stefano.panella@csr.com> Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-12-22uwb: use dev_dbg() for debug messagesDavid Vrabel
Instead of the home-grown d_fnstart(), d_fnend() and d_printf() macros, use dev_dbg() or remove the message entirely. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-19uwb: remove unused beacon group join/leave eventsDavid Vrabel
The UWB_NOTIF_BG_JOIN/UWB_NOTIF_BG_LEAVE events have been superceeded by the channel_changed callback in struct uwb_pal. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-19uwb: add basic radio managerDavid Vrabel
The UWB radio manager coordinates the use of the radio between the PALs that may be using it. PALs request use of the radio with uwb_radio_start() and the radio manager will start beaconing if its not already doing so. When the last PAL has called uwb_radio_stop() beaconing will be stopped. In the future, the radio manager will have a more sophisticated channel selection algorithm, probably following the Channel Selection Policy from the WiMedia Alliance when it is finalized. For now, channel 9 (BG1, TFC1) is selected. The user may override the channel selected by the radio manager and may force the radio to stop beaconing. The WUSB Host Controller PAL makes use of this and there are two new debug PAL commands that can be used for testing. Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-11-04uwb: per-radio controller event thread and beacon cacheStefano Panella
Use an event thread per-radio controller so processing events from one radio controller doesn't delay another. A radio controller shouldn't have information on devices seen by a different radio controller (they may be on different channels) so make the beacon cache per-radio controller.

2008-10-28uwb: order IEs by element IDDavid Vrabel
ECMA-368 requires that IEs in a beacon must be sorted by element ID. Most hardware uses the ordering in the Set IE URC command so get the ordering right on the host. Also refactor the IE management code: - use uwb_ie_next() instead of uwb_ie_for_each(). - remove unnecessary functions. - API is now only uwb_rc_ie_add() and uwb_rc_ie_rm().

2008-10-20uwb: wrong sizeof argument in mac address compareFrank Leipold
In the __uwb_beca_find_bymac function the sizeof returns the length of a pointer and not the data it is referring to. Hence only the first 4 bytes were compared, not the entire 6 bytes MAC address. Now the sizeof takes struct uwb_mac_addr as argument. Signed-off-by: Frank Leipold <frank.leipold@eads.net> Signed-off-by: David Vrabel <david.vrabel@csr.com>
2008-10-16uwb: don't use printk_ratelimit() so oftenDavid Vrabel
Avoid using printk_ratelimit() in many places because: - many were error messages reporting broken hardware (it's useful to get all of these). - the message itself wasn't useful so the message has been removed. Signed-off-by: David Vrabel <david.vrabel@csr.com>
