* at86rf230: remove version check for AT86RF212Andrey Yurovsky2014-12-191-10/+6
| | | | | | | | | | | | | | This version check allows the driver to only work with v=1 hardware however there is no driver-facing difference with newer versions (confirmed by Atmel FAEs) so this check needlessly prevents the driver from being used with radios now in production.

* | mac802154: add interframe spacing time handlingAlexander Aring2014-11-131-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new interframe spacing time handling into mac802154 layer. Interframe spacing time is a time period between each transmit. This patch adds a high resolution timer into mac802154 and starts on xmit complete with corresponding interframe spacing expire time if ifs_handling is true. We make it variable because it depends if interframe spacing time is handled by transceiver or mac802154. At the timer complete function we wake the netdev queue again. This avoids new frame transmit in range of interframe spacing time. For synced driver we add no handling of interframe spacing time. This is currently a lack of support in all synced xmit drivers. I suppose it's working because the latency of workqueue which is needed to call spi_sync. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
