2013-03-28net: add ETH_P_802_3_MINSimon Horman
Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for an 802.3 frame. Frames with a lower value in the ethernet type field are Ethernet II. Also update all the users of this value that David Miller and I could find to use the new constant. Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN should be >= not >. As suggested by Jesse Gross. Compile tested only. Cc: David Miller <davem@davemloft.net> Cc: Jesse Gross <jesse@nicira.com> Cc: Karsten Keil <isdn@linux-pingi.de> Cc: John W.

2013-03-18rt2x00: Fix tx status reporting for reordered frames in rt2800pciHelmut Schaa
rt2800 hardware sometimes reorders tx frames when transmitting to multiple BA enabled STAs concurrently. For example a tx queue [ STA1 | STA2 | STA1 | STA2 ] can result in the tx status reports [ STA1 | STA1 | STA2 | STA2 ] when the hw decides to put the frames for STA1 in one AMPDU. To mitigate this effect associate the currently processed tx status to the first frame in the tx queue with a matching wcid. This patch fixes several problems related to incorrect tx status reporting. Furthermore the tx rate selection is much more stable when communicating with multiple STAs.

2013-03-18mwifiex: fix race when queuing commandsAmitkumar Karwar
Running the following script repeatedly on XO-4 with SD8787 produces command timeout and system lockup. insmod mwifiex_sdio.ko sleep 1 ifconfig eth0 up iwlist eth0 scan & sleep 0.5 rmmod mwifiex_sdio mwifiex_send_cmd_async() is called for sync as well as async commands. (mwifiex_send_cmd_sync() internally calls it for sync command.) "adapter->cmd_queued" gets filled inside mwifiex_send_cmd_async() routine for both types of commands. But it is used only for sync commands in mwifiex_wait_queue_complete(). This could lead to a race when two threads try to queue a sync command with another sync/async command simultaneously. Get rid of global variable and pass command node as a parameter to mwifiex_wait_queue_complete() to fix the problem.

The commit 'ath9k_hw: fix calibration issues on chainmask that don't include chain 0' changed the hardware chainmask to the chip chainmask for the duration of the calibration, but the revert to user configuration in the reset path runs too early. That causes some issues with limiting the number of antennas (including spurious failure in hardware-generated packets). Fix this by reverting the chainmask after the essential parts of the calibration that need the workaround, and before NF calibration is run.

2013-03-18ath6kl: Fix the byte alignment rule to avoid loss of bytes in a TCP segmentMyoungje Kim
Either first 3 bytes of the first received tcp segment or last one over MTU size file can be loss due to the byte alignment problem. Although ATH6KL_HTC_ALIGN_BYTES was defined for 'extra bytes for htc header alignment' in the patch "Fix buffer alignment for scatter-gather I/O"(1df94a857), there exists the bytes loss issue which means that it will be truncated 3 bytes in the transmitted file contents if a file which has over MTU size is transferred through TCP/IP stack. It doesn't look like TCP/IP stack bug of 3.5 or the latest version of kernel but the byte alignment issue. This patch is to use the roundup() function for the byte alignment rather than the predefined ATH6KL_HTC_ALIGN_BYTES. kvalo: fixed indentation Signed-off-by: Myoungje Kim <mjei78@gmail.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2013-03-18ath6kl: remove false check from ath6kl_rx()Kalle Valo
Dan found a check from ath6kl_rx() which doesn't make any sense at all: " 1327 if (status || !(skb->data + HTC_HDR_LENGTH)) { ^^^^^^^^^^^^^^^^^^^^^^^^^^ skb->data is a pointer. This pointer math is always going to be false. Should it be testing "packet->act_len < HTC_HDR_LENGTH" or something?" I don't know what the check really was supposed to do, but I think Dan's guess is right. Fix it accordingly.

2013-03-18ath6kl: add an extra band check to ath6kl_wmi_beginscan_cmd()Kalle Valo
Dan reported that smatch found a possible issue in ath6kl_wmi_beginscan_cmd() where we might access sc->supp_rates beyond the end. It shouldn't happen as ar->wiphy->bands always have just the first two bands set, but add an extra check just to be sure.

2013-03-18ath6kl: add tracing support to debug message macrosKalle Valo
Now all log messages are sent through the tracing infrastruture as well. Tracing point doesn't follow debug_mask module parameter, instead it sends all debug messages, so once you enable ath6kl_log_dbg tracing point you will get a lot of messages. Needs to be discussed if this is sensible or not. The overhead should be small enough and we anyway include debug level as well so it's easy to filter in user space. I wasn't really sure what to do with ath6kl_dbg_dump() and for now decided that it also sends the buffer to user space. But most likely in the future ath6kl_dbg_dump() should go away in favor of using proper tracing points, but we will see. Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
