[PATCH BlueZ] shared/bap: ucast streams can only have one link

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

 



In unicast, linked streams mean bidirectional CIS.  Ucast stream can
have at most one linked stream.

Fix ucast streams to have only single link. This fixes eg. configuring
for AC 11(i).
