* ath9k: add external_reset callback to ath9k_platfom_data for AR9330Gabor Juhos2011-06-22
| | | | | | | | | | | | The patch adds a callback to ath9k_platform_data. If the callback is provided by the platform code, then it can be used to hard reset the WMAC device. The callback is required for doing a hard reset of the AR9330 chips to get them working again after a hang. Signed-off-by: Gabor Juhos <juhosg@openwrt.org> Signed-off-by: John W.

* nl80211: use netlink consistent dump feature for BSS dumpsJohannes Berg2011-06-22
| | | | | | | | | | | | | | | | Use the new consistent dump feature from (generic) netlink to advertise when dumps are incomplete. Readers may note that this does not initialize the rdev->bss_generation counter to a non-zero value. This is still OK since the value is modified only under spinlock when the list is modified. Since the dump code holds the spinlock, the value will either be > 0 already, or the list will still be empty in which case a consistent dump will actually be made (and be empty).

* zd1211rw: detect stalled beacon interrupt fasterJussi Kivilinna2011-06-22
| | | | | | | | | | | | As USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS, beacon interrupt (CR_INTERRUPT) might be lost. Problem is that when device trigger CR_INTERRUPT it disables HW interrupt. Now if USB_INT_ID_REGS with CR_INTERRUPT gets lost, beacon interrupt stays disabled until beacon watchdog notices the stall. This happen very often on heavy TX. Improve watchdog to trigger earlier, after three missing beacon interrupts. Signed-off-by: Jussi Kivilinna <jussi.kivilinna@mbnet.fi> Signed-off-by: John W.

* zd1211rw: don't let zd_mac_config_beacon() run too long from beacon ↵Jussi Kivilinna2011-06-22
| | | | | | | | | | | | | interrupt handler zd_mac_config_beacon() has only limited time to set up beacon when called from beacon interrupt handler/worker. So do not let it retry acquiring beacon fifo semaphore in interrupt handler. Beacon fifo semaphore should not be locked by firmware anyway at this time, it's only locked when device is using/txing beacon.

* zd1211rw: handle lost read-reg interruptsJussi Kivilinna2011-06-22
| | | | | | | | | | | | | | | | | | Device losses read-reg interrupts. By looking at usbmon it appears that USB_INT_ID_RETRY_FAILED can override USB_INT_ID_REGS. This causes read command to timeout, usually under heavy TX. Fix by retrying read registers again if USB_INT_ID_RETRY_FAILED is received while waiting for USB_INT_ID_REGS. However USB_INT_ID_REGS is not always lost but is received after USB_INT_ID_RETRY_FAILED and is usually received by the retried read command. USB_INT_ID_REGS of the retry is then left unhandled and might be received by next read command. Handle this by ignoring previous USB_INT_ID_REGS that doesn't match current read command request.

* zd1211rw: fix invalid signal values from deviceJussi Kivilinna2011-06-22
| | | | | | | | | | | | | Driver uses IEEE80211_HW_SIGNAL_UNSPEC and so signal values reported to mac80211 should be in range 0..100. Sometimes device return out of range values. These out of range values can then trigger warning in cfg80211_inform_bss_frame. This patch adds checks to enforce range returned from driver to mac80211 be in 0..100 range.

* netlink: advertise incomplete dumpsJohannes Berg2011-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Consider the following situation: * a dump that would show 8 entries, four in the first round, and four in the second * between the first and second rounds, 6 entries are removed * now the second round will not show any entry, and even if there is a sequence/generation counter the application will not know To solve this problem, add a new flag NLM_F_DUMP_INTR to the netlink header that indicates the dump wasn't consistent, this flag can also be set on the MSG_DONE message that terminates the dump, and as such above situation can be detected. To achieve this, add a sequence counter to the netlink callback struct. Of course, netlink code still needs to use this new functionality. The correct way to do that is to always set cb->seq when a dumpit callback is invoked and call nl_dump_check_consistent() for each new message. The core code will also call this function for the final MSG_DONE message. To make it usable with generic netlink, a new function genlmsg_nlhdr() is needed to obtain the netlink header from the genetlink user header.

Unfortunately device may sometimes still does not operate correctly after module reload (fail to receive data after associate), but such cases are rarer than without the patch.
