Phoebe talked about this issues several weeks ago, if you have any improvements to this driver, please send patches with git send-email to this list. Then we review it and you can send it to netdev. I really don't like to send it directly to netdev, of course you can do that but if you don't already realized that. The complete stack and 6lowpan isn't maintained so david miller waits ~4 hours and apply it to his branches and I don't have 4 hours to review and test it... sometimes. - Alex ------------------------------------------------------------------------------ _______________________________________________ Linux-zigbee-devel mailing list Linux-zigbee-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linux-zigbee-devel
