This patch passes that flag to the net_proto_family specific create function, so it can do the same thing. Signed-off-by: Eric Paris Acked-by: Arnaldo Carvalho de Melo Signed-off-by: David S.

The local entity can retransmit again only when it receives a SREJ frame with the F-bit set. SREJ frame - Selective Reject frame - is sent when an entity wants the retransmission of a specific I-frame that was lost or corrupted. This bug can put ERTM in an unknown state once the entity can't retransmit. A frame with the Final bit set is expected when the local side sends a frame with the Poll bit set due to a local busy condition or a retransmission timer expired.

Padovan" Date: Sat, 3 Oct 2009 02:34:38 -0300 Subject: Bluetooth: Fix sending ReqSeq on I-frames As specified by ERTM spec an ERTM channel can acknowledge received I-frames(the data frames) by sending an I-frame with the proper ReqSeq value (i.e. ReqSeq is set to BufferSeq). Until now we aren't setting the ReqSeq value on I-frame control bits. That way we can save sending S-frames(Supervise frames) only to acknowledge receipt of I-frames. It is very helpful to the full-duplex channel. ReqSeq is the packet sequence number sent in an acknowledgement frame to acknowledge receipt of frames up to (ReqSeq - 1). BufferSeq controls the receiver buffer, it is used to delay acknowledgement of new frames to not cause buffer overflow. BufferSeq value is not increased until frames are pulled by reassembly function. Signed-off-by: Gustavo F.
