So entries +between Q_INDEX_DONE and Q_INDEX are those we currently process in the +hardware. Entries between Q_INDEX and Q_INDEX_DONE are those we can +submit to the hardware. + +According to that fix rt2x00usb_kick_queue(), as we need to submit rx +entries that are not processed by the hardware. It worked before only +for empty queue, otherwise was broken. + +Note that for TX queues indexes ordering are ok. We need to kick entries +that have filled skb, but was not submitted to the hardware, i.e. +strted from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set. + +From practical standpoint this patch fixes AP mode connection hangs. + +Signed-off-by: Stanislaw Gruszka +--- + drivers/net/wireless/rt2x00/rt2x00usb.c | 2 +- + 1 files changed, 1 insertions(+), 1 deletions(-) + +diff --git a/drivers/net/wireless/rt2x00/rt2x00usb.c b/drivers/net/wireless/rt2x00/rt2x00usb.c +index d357d1e..74ecc33 100644 +--- a/drivers/net/wireless/rt2x00/rt2x00usb.c ++++ b/drivers/net/wireless/rt2x00/rt2x00usb.c +@@ -436,8 +436,8 @@ void rt2x00usb_kick_queue(struct data_queue *queue) + case QID_RX: + if (!rt2x00queue_full(queue)) + rt2x00queue_for_each_entry(queue, +- Q_INDEX_DONE, + Q_INDEX, ++ Q_INDEX_DONE, + NULL, + rt2x00usb_kick_rx_entry); + break; +-- +1.7.1 +
