2008-02-28rt2x00: Add link tuner safe RX toggle statesIvo van Doorn
This adds 2 new states which both are used to toggle the RX. These new states are required for usage inside the link tuner thread, because the normal RX toggling will stop the link tuner thread. While it is possible that the link tuner thread itself is the caller of the RX toggle (when using software antenna diversity). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-01-28rt2x00: Data and desc pointer initializationIvo van Doorn
rt2500usb and rt73usb data and desc pointer initialization was incorrect because it was using uninitialized variables to determine the length. In addition rt2500usb used skb_pull and removed the ieee80211 from each received frame instead of using skb_trim to remove the device descriptor from the frame. Finally this also fixes the descriptor override when 4 byte aligning occured. We still need a completely valid descriptor when using the TX/RX dumping capabilities in debugfs.

2008-01-28mac80211: add unified BSS configurationJohannes Berg
This patch (based on Ron Rindjunsky's) creates a framework for a unified way to pass BSS configuration to drivers that require the information, e.g. for implementing power save mode. This patch introduces new ieee80211_bss_conf structure that is passed to the driver via the new bss_info_changed() callback when the BSS configuration changes. This new BSS configuration infrastructure adds the following new features: * drivers are notified of their association AID * drivers are notified of association status and replaces the erp_ie_changed() callback. The patch also does the relevant driver updates for the latter change.

2008-01-28rt2x00: Correctly initialize data and desc pointerIvo van Doorn
rt2500usb and rt73usb store the descriptor in different places. This means we should move the initialization of the 2 pointers to the driver callback function fill_rxdone(). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-01-28rt2x00: Determine MY_BSS from descriptorIvo van Doorn

2008-01-28rt2x00: Cleanup write_tx_desc() argumentsIvo van Doorn
Send the skb structure with write_tx_desc() and use the skbdesc structure to read all information about the frame.

2008-01-28rt2x00: Move packet filter flagsIvo van Doorn
The packet filter flags don't belong in the interface structure because they are device based instead of interface based. So move the filter fields out of struct interface and into rt2x00_dev. Additionally we shouldn't change the filter based on the working mode, if such a thing is needed than mac80211 should have done that.

2008-01-28rt2x00: Only set the TBCN flag when the interface is configured to send beacons.Ivo van Doorn
These flags used to be fixed to one in rt2500pci_config_type, which caused the beacon timer interrupt to fire. This would lead to rt2x00lib_beacondone adding work which called rt2x00lib_beacondone_scheduled which called ieee80211_beacon_get which printed an error about not having any beacon data. With this patch, these interrupts are only generated when the interface is configured to send beacons.

2008-01-28rt2x00: Correctly set ACK bit in tx descriptorsMattias Nissler
Add a flag to struct txdata_entry_desc that specifies whether an ack for the frame is to be expected. Use this flag to set the ACK bit in the tx descriptor. Previously, the ACK bit could be set incorrectly on CTS-to-self frames, so they caused retries and were reported to be failed in the txdone handlers.

2008-01-28rt2x00: Place mutex around USB register accessAdam Baker
There is a buffer, csr_cache which is used to hold copies of data being passed to the USB stack which can get corrupted if multiple threads attempt to access CSR registers simultaneously. There is also the possibility if multiple threads try to access BBP or RF registers for the multiple USB operations needed to get interleaved leading to incorrect results. This patch introduces a mutex to prevent such simultaneous access. The interleaved access problem may also affect the PCI devices but if so that will be handled in a follow-up patch.

2008-01-28[PATCH] rt2x00: SW diversity should default to antenna BIvo van Doorn

2008-01-28[PATCH] rt2x00: Correctly translate mac80211 antenna setup to rt2x00Ivo van Doorn
mac80211 has 3 values for the antenna setup: 0 - default 1 - use antenna 1 2 - use antenna 2 This means that rt2x00 should store the default value from the EEPROM somwhere and use that when mac80211 indicates that the antenna setup is 0. This also implies that rt2x00 should no longer write the hw->config.antenna_sel_* values based on the EEPROM input. This also adds the basis in rt2x00lib for correct software diversity handling. By default rt2x00lib will now configure antenna B instead of hardware diversity. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2007-11-18rt2x00: Request usb_maxpacket() onceIvo van Doorn

2007-11-14rt2x00: Fix chipset revision validationIvo van Doorn
The validation of the chipset revision was broken since for rt2500usb and rt73usb different registers should be read. When rt2500usb was loaded for a rt73 device it would false think the chipset was correct because the wrong register was read and validated. This has been fixed by expanding the check to also see if the first 4 bits of the revision is not-0 (When reading the wrong register offset the returned value is usually 0 which can be interpreted as invalid) Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2007-10-10[PATCH] rt2x00: Reorganize configuration handlerIvo van Doorn
Reorganize configuration handling by creating a extra structure which contains precalculated values based on the mac80211 values which are usefull for all individual drivers. This also fixes the preamble configuration problem, up untill now preamble was never configured since by default the rate->val value was used when changing the mode. Now rate->val will only be used to set the basic rate mask. The preamble configuration will now be done correctly through the erp_ie_changed callback function.

The TX datalen must always be converted to a value rt73 and rt2500usb understand. Both require to use a different size then skb->len. First off this is required because the descriptor must be added, but the second is because the value must be a multiple of either 2 or 4, and it should not be a multiple of the USB packetmax Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2007-10-10[PATCH] rt2x00: Don't use changed_flags inside configure_packet_filterIvo van Doorn
We shouldn't use changed_flags when configuring the packet filter, we work directly with the total_flags which is safe enough since we already check if something has changed after we applied our packet filtering flag rules. Also make sure that when the packet filter is scheduled, the rt2x00dev->interface.filter is cleared to make sure the drivers will update the packet filter instead of failing at the check: *total_flags == rt2x00dev->interface.filter Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2007-10-10[PATCH] mac80211: revamp interface and filter configurationJohannes Berg
Drivers are currently supposed to keep track of monitor interfaces if they allow so-called "hard" monitor, and they are also supposed to keep track of multicast etc. This patch changes that, replaces the set_multicast_list() callback with a new configure_filter() callback that takes filter flags (FIF_*) instead of interface flags (IFF_*). For a driver, this means it should open the filter as much as necessary to get all frames requested by the filter flags. Accordingly, the filter flags are named "positively", e.g. FIF_ALLMULTI. Multicast filtering is a bit special in that drivers that have no multicast address filters need to allow multicast frames through when either the FIF_ALLMULTI flag is set or when the mc_count value is positive. At the same time, drivers are no longer notified about monitor interfaces at all, this means they now need to implement the start() and stop() callbacks and the new change_filter_flags() callback. Also, the start()/stop() ordering changed, start() is now called *before* any add_interface() as it really should be, and stop() after any remove_interface(). The patch also changes the behaviour of setting the bssid to multicast for scanning when IEEE80211_HW_NO_PROBE_FILTERING is set; the IEEE80211_HW_NO_PROBE_FILTERING flag is removed and the filter flag FIF_BCN_PRBRESP_PROMISC introduced. This is a lot more efficient for hardware like b43 that supports it and other hardware can still set the BSSID to all-ones.
