[RFCv7 18/23] Bluetooth: physical link HCI interface to AMP

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Andrei Emeltchenko <andrei.emeltchenko@xxxxxxxxx>

Adds support for physical link create/acceppt/disconnect AMP HCI
commands. To be used by the upper layer.
Backport from CodeAurora & Atheros
