====================
pull request: bluetooth-next 2015-08-16

Here's what's likely the last bluetooth-next pull request for 4.3:

 - 6lowpan/802.15.4 refactoring, cleanups & fixes
 - Document 6lowpan netdev usage in Documentation/networking/6lowpan.txt
 - Support for UART based QCA Bluetooth controllers
 - Power management support for Broeadcom Bluetooth controllers
 - Change LE connection initiation to always use passive scanning first
 - Support for new Silicon Wave USB ID

Please let me know if there are any issues pulling. Thanks.
