For reasons not very clear yet to me, filter_ack leaves matching tx-packet pending with 'ack_pending'. This causes tx-packet to be passed back to upper layer after next packet has been transfered and tx-packets might end up coming come out of monitor interface in wrong order vs. rx. Because of this when enable AP-mode, hostapd monitor interface would get packets in wrong order causing problems in WPA association. So don't use mac->ack_pending when in AP-mode.

Vendor driver uses CR_BNC_INTERVAL at various places, one is HW_EnableBeacon() that combinies beacon interval with BSS-type flag and DTIM value in upper 16bit of u32. The other one is HW_UpdateBcnInterval() that set_aw_pt_bi() appears to be based on. HW_UpdateBcnInterval() takes interval argument as u16 and uses that for calculations, set_aw_pt_bi() uses u32 value that has flags and dtim in upper part. This clearly seems wrong. Also HW_UpdateBcnInterval() updates only lower 16bit part of CR_BNC_INTERVAL. So make set_aw_pt_bi() do calculations on only lower u16 part of s->beacon_interval. Also set 32bit beacon interval register before reading values from device, as HW_EnableBeacon() on vendor driver does. This is required to make beacon work on AP-mode, simply reading and then writing updated values is not enough at least with zd1211b.

When stress testing AP-mode I hit OOPS when unpluging or rmmodding driver. It appears that when tx-queue is disabled, tx-urbs might be left pending. These can cause ehci to call non-existing tx_urb_complete() (after rmmod) or uninitialized/reseted private structure (after disconnect()). Add skb queue for submitted packets and unlink pending urbs on zd_usb_disable_tx(). Part of the problem seems to be usb->free_urb_list that isn't always working as it should, causing machine freeze when trying to free the list in zd_usb_disable_tx(). Caching free urbs isn't what other drivers seem to be doing (usbnet for example) so strip free_usb_list. Patch makes tx-urb handling saner with use of urb anchors.

TKIP countermeasures depend on devices being able to detect Michael MIC failures on received frames and for stations to report errors to the AP. In order to test that behavior, it is useful to be able to send out TKIP frames with incorrect Michael MIC. This testing behavior has minimal effect on the TX path, so it can be added to mac80211 for convenient use. The interface for using this functionality is a file in mac80211 netdev debugfs (tkip_mic_test). Writing a MAC address to the file makes mac80211 generate a dummy data frame that will be sent out using invalid Michael MIC value. In AP mode, the address needs to be for one of the associated stations or ff:ff:ff:ff:ff:ff to use a broadcast frame. In station mode, the address can be anything, e.g., the current BSSID. It should be noted that this functionality works correctly only when associated and using TKIP.

The TKIP implementation was originally prepared to be a bit more flexible in the way Michael MIC TX/RX keys are configured. However, we are now taking care of the TX/RX MIC key swapping in user space, so this code will not be needed. Similarly, there were some remaining WPA testing code that won't be used in their current form. Remove the unneeded extra complexity.

When operating in AP mode the wl1271 hardware filters out null-data packets as well as management packets. This makes it impossible for mac80211 to monitor the PS mode by using the PM bit of incoming frames. Implement a HW flag to indicate that mac80211 should ignore the PM bit. In addition, expose ieee80211_sta_ps_transition() to make low-level drivers capable of controlling PS-mode. Signed-off-by: NArik Nemtsov <arik@wizery.com> Signed-off-by: NJohn W.

When rate-control is performed in HW, we cannot calculate frame duration as we do not have the skb transmission rate in SW. ieee80211_tx_h_calculate_duration() should only be called when ieee80211_tx_h_rate_ctrl() has been called before to initialize data in skb->cb. This doesn't happen for drivers with HW rate-control. Fixes the following warning when operating in AP-mode in a driver with HW rate-control.

Currently cfg80211 only configures the PSM state to the driver upon creation of a new virtual interface, but not after interface type change. The mac80211 on the other hand reinitializes its sdata structure every time the interface type is changed, losing the PSM configuration. Hence, if the interface type is changed to, say, ad-hoc and then back to managed, "iw wlan0 get power_save" will claim that PSM is enabled, when in fact on mac80211 level it is not. Fix this in cfg80211 by configuring the PSM state to the driver each time the interface is brought up instead of just when the interface is created.

The queue stopping/waking functionality was broken in a way that could cause the TX to stall if the right circumstances are met. The problem was caused by tx_work, which is scheduled on each TX operation. If the firmware buffer is full, tx_work does nothing. In combinition with stopped queues or non-continues transfers, tx_work is never scheduled again. Moreover the low watermark introduced by 9df86e2e never takes effect because of some old code. Solve this by scheduling tx_work every time tx_queue is non-empty and firmware buffer is freed on tx_complete. This also solves a possible but unlikely case: If less frames than the high watermark are queued, but more than firmware buffer can hold. This results in queues staying awake but the only scheduled tx_work doesn't transfer all frames, so the remaining frames are stuck in the queue until more frames get queued and tx_work is scheduled again.
