Hi, These patches enable some parts of Enhanced Retransmission Mode. Now we already support Sending I-frames; acknowledgment of packets; segmentation and reassembly of SDU; retransmission of I-frames due to a recept of a S-frame; and retransmission and monitor timers. Still need to be done: treatment of busy conditions; support to ask retransmission using a SREJ S-frame; implement missing parts of this things; and put all this code to work together as specified by L2CAP ERTM state tables. Then we will have Enhanced Retransmission on Bluez! :-) Cheers! include/net/bluetooth/bluetooth.h | 4 +- include/net/bluetooth/l2cap.h | 82 +++++- net/bluetooth/l2cap.c | 633 ++++++++++++++++++++++++++++++++----- 3 files changed, 631 insertions(+), 88 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-bluetooth" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
