Bluetooth: Add Kconfig option for L2CAP Extended Features
The L2CAP Extended Features are still unstable and under development, so we are adding them under the EXPERIMENTAL flag to get more feedback on them. L2CAP Extended Features includes the Enhanced Retransmission and Streaming Modes, Frame Check Sequence (FCS), and Segmentation and Reassemby (SAR). Signed-off-by: Gustavo F. Padovan <padovan@profusion.mobi> Reviewed-by: João Paulo Rechi Vita <jprvita@profusion.mobi> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
