The patch titled
bluetooth: fix problem with sco
has been removed from the -mm tree. Its filename is
bluetooth-fix-problem-with-sco.patch
This patch was probably dropped from -mm because
it has now been merged into a subsystem tree or
into Linus's tree, or because it was folded into
its parent patch in the -mm tree.
From: Wolfgang Walter <wolfgang.walter@xxxxxxxxxxxxxxxxxxxx>
A friend and I encountered a problem with sco transfers to a headset using
linux (vanilla 2.6.15). While all sco packets sent by the headset were
received there was no outgoing traffic.
After switching debugging output on we found that actually sco_cnt was
always zero in hci_sched_sco.
hciconfig hci0 shows sco_mtu to be 64:0. Changing that to 64:8 did not help.
This was because in hci_cc_info_param hdev->sco_pkts is set to zero. When
we changed this line so that hdev->sco_pkts is set to 8 if bs->sco_max_pkt
is 0 sco transfer to the headset started to work just fine.
