Unloading rt61pci can leave the device in such state that reloading rt61pci would fail to reinitialize it. Bogus data would be read from the EEPROM and the RF version won't be recognized. It appears that unloading rt61pci with power saving enabled would have such effect. To initialize the device properly, SOFT_RESET_CSR should be set to the same value as rt61pci_config_ps() uses to wake up the device. Signed-off-by:

As shown in http://thread.gmane.org/gmane.linux.kernel.wireless.general/36497, mac80211 has a bug that allows a call to the TX routine after the queues have been stopped. This situation will only occur under extreme stress. Although b43legacy does not crash when this condition occurs, it does generate a WARN_ON and also logs a queue overrun message. This patch recognizes b43legacy is not at fault and logs a message only when the most verbose debugging mode is enabled. In the unlikely event that the queue is not stopped when the DMA queue becomes full, then a warning is issued. This patch is based on the one used by b43. Signed-off-by:

For 6x00 2x2 NIC, two types of Power Amplifier are available. In order for uCode to apply correct tx power, driver needs to program the CSR_GP_DRIVER_REG register and let uCode know the type of PA. If driver do not program CSR_GP_DRIVER_REG register (default to 0), then it is uCode's decision for tx power 2x2 Hybrid card: use both internal and external PA 2x2 IPA(Internal Power Amplifier) card: internal PA only Signed-off-by:

The SPI driver writes to the bus mode register and performs a sanity check by reading back what we wrote, however only the lower four bits of that register are defined. In some cases, the device side seems to set the higher bits, causing us to fail the sanity check unnecessarily. Check only the lower four bits instead. Thanks to John Goyette from Schick Technologies for pointing out the problem. Signed-off-by:

Do a probe request every 30 seconds, and wait for probe response, half a second This should lower the traffic that card sends, thus save power Wainting longer for response makes probe more robust against 'slow' access points Signed-off-by:

The default of 500ms is pretty high, and leads to the device being awake at least 50% of the time under such light traffic conditions as a simple 1 second interval ping. Reduce to just 100ms -- it should have a similar effect while providing a better sleep time. Signed-off-by:

Since the bss is always set now once we are connected, if the bss has its own information element we refer to it and pass that instead of relying on mac80211's parsing. Now all cfg80211 drivers get country IE support, automatically and we reduce the call overhead that we had on mac80211 which called this upon every beacon and instead now call this only upon a successfull connection by a STA on cfg80211.

We change regulatory code to be protected by its own regulatory mutex and alleviate cfg80211_mutex to only be used to protect cfg80211_rdev_list, the registered device list. By doing this we will be able to work on regulatory core components without having to have hog up the cfg80211_mutex. An example here is we no longer need to use the cfg80211_mutex during driver specific wiphy_apply_custom_regulatory(). We also no longer need it for the the country IE regulatory hint; by doing so we end up curing this new lockdep warning: ======================================================= [ INFO: possible circular locking dependency detected ] 2.6.31-rc4-wl #12 ------------------------------------------------------- phy1/1709 is trying to acquire lock: (cfg80211_mutex){+.+.+.}, at: [<ffffffffa00af852>] regulatory_hint_11d+0x32/0x3f0 [cfg80211] but task is already holding lock: (&ifmgd->mtx){+.+.+.}, at: [<ffffffffa0144228>] ieee80211_sta_work+0x108/0x10f0 [mac80211] which lock already depends on the new lock. the existing dependency chain (in reverse order) is: -> #3 (&ifmgd->mtx){+.+.+.}: [<ffffffff810857b6>] __lock_acquire+0xd76/0x12b0 [<ffffffff81085dd3>] lock_acquire+0xe3/0x120 [<ffffffff814eeae4>] mutex_lock_nested+0x44/0x350 [<ffffffffa0141bb8>] ieee80211_mgd_auth+0x108/0x1f0 [mac80211] [<ffffffffa0148563>] ieee80211_auth+0x13/0x20 [mac80211] [<ffffffffa00bc3a1>] __cfg80211_mlme_auth+0x1b1/0x2a0 [cfg80211] [<ffffffffa00bc516>] cfg80211_mlme_auth+0x86/0xc0 [cfg80211] [<ffffffffa00b368d>] nl80211_authenticate+0x21d/0x230 [cfg80211] [<ffffffff81416ba6>] genl_rcv_msg+0x1b6/0x1f0 [<ffffffff81415c39>] netlink_rcv_skb+0x89/0xb0 [<ffffffff814169d9>] genl_rcv+0x29/0x40 [<ffffffff8141591d>] netlink_unicast+0x29d/0x2b0 [<ffffffff81416514>] netlink_sendmsg+0x214/0x300 [<ffffffff813e4407>] sock_sendmsg+0x107/0x130 [<ffffffff813e45b9>] sys_sendmsg+0x189/0x320 [<ffffffff81011f82>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff -> #2 (&wdev->mtx){+.+.+.}: [<ffffffff810857b6>] __lock_acquire+0xd76/0x12b0 [<ffffffff81085dd3>] lock_acquire+0xe3/0x120 [<ffffffff814eeae4>] mutex_lock_nested+0x44/0x350 [<ffffffffa00ab304>] cfg80211_netdev_notifier_call+0x1a4/0x390 [cfg80211] [<ffffffff814f3dff>] notifier_call_chain+0x3f/0x80 [<ffffffff81075a91>] raw_notifier_call_chain+0x11/0x20 [<ffffffff813f665a>] dev_open+0x10a/0x120 [<ffffffff813f59bd>] dev_change_flags+0x9d/0x1e0 [<ffffffff8144eb6e>] devinet_ioctl+0x6fe/0x760 [<ffffffff81450204>] inet_ioctl+0x94/0xc0 [<ffffffff813e25fa>] sock_ioctl+0x6a/0x290 [<ffffffff8111e911>] vfs_ioctl+0x31/0xa0 [<ffffffff8111ea9a>] do_vfs_ioctl+0x8a/0x5c0 [<ffffffff8111f069>] sys_ioctl+0x99/0xa0 [<ffffffff81011f82>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff -> #1 (&rdev->mtx){+.+.+.}: [<ffffffff810857b6>] __lock_acquire+0xd76/0x12b0 [<ffffffff81085dd3>] lock_acquire+0xe3/0x120 [<ffffffff814eeae4>] mutex_lock_nested+0x44/0x350 [<ffffffffa00ac4d0>] cfg80211_get_dev_from_ifindex+0x60/0x90 [cfg80211] [<ffffffffa00b21ff>] get_rdev_dev_by_info_ifindex+0x6f/0xa0 [cfg80211] [<ffffffffa00b51eb>] nl80211_set_interface+0x3b/0x260 [cfg80211] [<ffffffff81416ba6>] genl_rcv_msg+0x1b6/0x1f0 [<ffffffff81415c39>] netlink_rcv_skb+0x89/0xb0 [<ffffffff814169d9>] genl_rcv+0x29/0x40 [<ffffffff8141591d>] netlink_unicast+0x29d/0x2b0 [<ffffffff81416514>] netlink_sendmsg+0x214/0x300 [<ffffffff813e4407>] sock_sendmsg+0x107/0x130 [<ffffffff813e45b9>] sys_sendmsg+0x189/0x320 [<ffffffff81011f82>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff other info that might help us debug this: 3 locks held by phy1/1709: #0: ((wiphy_name(local->hw.wiphy))){+.+.+.}, at: [<ffffffff8106b45d>] worker_thread+0x19d/0x340 #1: (&ifmgd->work){+.+.+.}, at: [<ffffffff8106b45d>] worker_thread+0x19d/0x340 #2: (&ifmgd->mtx){+.+.+.}, at: [<ffffffffa0144228>] ieee80211_sta_work+0x108/0x10f0 [mac80211] Reported-by: -

Simplify the country IE hint code by just bailing out if a previous country IE has been issued. We currently just trust the first AP we connect to on any card. The idea was to perform conflict resolution within this routine but since we can no longer iterate over the registered device list here we leave conflict resolution to be dealt with at a later time on the workqueue. This code has no functional changes other than saving us an interation over the registered device list when a second card is connected, or you unplug and connect the same one, and a country IE is received. This would have been done upon every beacon received. Signed-off-by:

Some of the recent MLME rework I did broke powersave because the ps_sdata isn't assigned at the right time, and the work item wasn't removed from the list before calling ieee80211_recalc_ps(). To be more specific, this broke the case where you'd enabled PS before associating, either automatically or with iwconfig. Signed-off-by:

It's possible to get the NETDEV_UNREGISTER callback multiple times (see net/core/dev.c:netdev_wait_allrefs) and this will completely mess up our cleanup code. To avoid that, clean up only when the interface is still on the wiphy interface list from which it's removed on the first NETDEV_UNREGISTER call. Signed-off-by:

The mac80211 workqueue exists to enable mac80211 and drivers to queue their own work on a single threaded workqueue. mac80211 takes care to flush the workqueue during suspend but we never really had requirements on drivers for how they should use the workqueue in consideration for suspend. We extend mac80211 to document how the mac80211 workqueue should be used, how it should not be used and finally move raw access to the workqueue to mac80211 only. Drivers and mac80211 use helpers to queue work onto the mac80211 workqueue: * ieee80211_queue_work() * ieee80211_queue_delayed_work() These helpers will now warn if mac80211 already completed its suspend cycle and someone is trying to queue work. mac80211 flushes the mac80211 workqueue prior to suspend a few times, but we haven't taken the care to ensure drivers won't add more work after suspend. To help with this we add a warning when someone tries to add work and mac80211 already completed the suspend cycle. Drivers should ensure they cancel any work or delayed work in the mac80211 stop() callback. Signed-off-by:

This driver only uses the mac80211 workqueue and mac80211 requires us to cancel all work at driver stop. Since we now have the cancels in the right places at stop() we really don't need to flush the mac80211 workqueue so remove it. Signed-off-by:
