linux-toradex.git/drivers/net/wireless/rt2x00, branch v3.0.49 Linux kernel for Apalis and Colibri modules rt2x00: Fix rfkill polling prior to interface start. 2012-10-02T16:47:37+00:00 Gertjan van Wingerde gwingerde@gmail.com 2012-08-31T17:22:11+00:00 b4395a14b80188c83d6b126f5617d2f1be852b2d commit a396e10019eaf3809b0219c966865aaafec12630 upstream. We need to program the rfkill switch GPIO pin direction to input at device initialization time, not only when the interface is brought up. Doing this only when the interface is brought up could lead to rfkill detecting the switch is turned on erroneously and inability to create the interface and bringing it up.

commit a396e10019eaf3809b0219c966865aaafec12630 upstream.

We need to program the rfkill switch GPIO pin direction to input at
device initialization time, not only when the interface is brought up.
Doing this only when the interface is brought up could lead to rfkill
detecting the switch is turned on erroneously and inability to create
the interface and bringing it up.

rt2x00usb: fix indexes ordering on RX queue kick 2012-07-19T15:58:21+00:00 Stanislaw Gruszka sgruszka@redhat.com 2012-07-04T11:10:02+00:00 16f1a5d495c4c8bd246c96052ab5a0fc4fd03646 commit efd821182cec8c92babef6e00a95066d3252fda4 upstream. On rt2x00_dmastart() we increase index specified by Q_INDEX and on rt2x00_dmadone() we increase index specified by Q_INDEX_DONE. 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. started from Q_INDEX_DONE and have ENTRY_DATA_PENDING bit set. From practical standpoint this fixes RX queue stall, usually reproducible in AP mode, like for example reported here: https://bugzilla.redhat.com/show_bug.cgi?id=828824 Reported-and-tested-by: Franco Miceli <fmiceli@plan.ceibal.edu.uy> Reported-and-tested-by: Tom Horsley <horsley1953@gmail.com> Signed-off-by: Stanislaw Gruszka <sgruszka@redhat.com> Signed-off-by: John W.
