2012-02-01rt2800lib: fix wrong -128dBm when signal is stronger than -12dBmLuigi Tarenga
This patch correct the type of variables containing the rssi values read from the rxwi. In function rt2800_agc_to_rssi() 3 variables (rssi0, rssi1, rss2) defined as int was assigned a 16bit signed values as unsigned. From a test with a hi-gain antenna I verified that the rxwi contains signed rssi values in the range -13/+81 (inclusive) with 0 as an error condition. In case of negative values a condition is triggered and the function return -128dBm while the signal is at its maximum. This patch correct the cast so negative values are not treated as very high positive values (ex. -13 does not become 243).

2011-09-14rt2x00: Make use of sta_add/remove callbacks in rt2800Helmut Schaa
This allows us to assign a WCID to each STA even for STAs without crypto key. To achieve this search for an unused WCID in the HW WCID table and assign it to the according STA. When configuring a pairwise key for this STA we don't need to write the MAC address and BSSIDX anymore but just update the crypto related fields in the WCID_ATTR table. This has two advantages: 1) Setting a new key for an already available STA (PTK rekeying) is slightly less expensive and should improve performance in situations where a lot of rekeying happens (e.g. a huge number of stations and/or a small rekeying interval) 2) The TXWI now gets a WCID assigned for unencrypted frames which will be reflected in the corresponding tx status report. This should make tx status reports in unencrypted AP mode more reliable as we can distinguish between multiple key-less STAs.

2011-04-19rt2800usb: read TX_STA_FIFO asynchronouslyJohannes Stezenbach
Trying to fix the "TX status report missed" warnings by reading the TX_STA_FIFO entries as quickly as possible. The TX_STA_FIFO is too small in hardware, thus reading it only from the workqueue is too slow and entries get lost. Start an asynchronous read of the TX_STA_FIFO directly from the TX URB completion callback (atomic context, thus it cannot use the blocking rt2800_register_read()). If the async read returns a valid FIFO entry, it is pushed into a larger FIFO inside struct rt2x00_dev, until rt2800_txdone() picks it up. A .tx_dma_done callback is added to struct rt2x00lib_ops to trigger the async read from the URB completion callback.

2011-04-19rt2x00: Split rt2x00dev->flagsIvo van Doorn
The number of flags defined for the rt2x00dev->flags field, has been growing over the years. Currently we are approaching the maximum number of bits which are available in the field. A secondary problem, is that one part of the field are initialized only during boot, because the driver requirements are initialized or device requirements are loaded from the EEPROM. In both cases, the flags are fixed and will not change during device operation. The other flags are the device state, and will change frequently. So far this resulted in the fact that for some flags, the atomic bit accessors are used, while for the others the non-atomic variants are used. By splitting the flags up into a "flags" and "cap_flags" we can put all flags which are fixed inside "cap_flags". This field can then be read non-atomically. In the "flags" field we keep the device state, which is going to be read atomically. This adds more room for more flags in the future, and sanitizes the field access methods.

Some clients seem to rely upon the reception of BlockAckReqs to flush their rx reorder buffer.

When setting up multiple BSSIDs in AP mode on an rt2800pci device we previously used the STAs AID to select an appropriate key slot. But since the AID is per VIF we can end up with two STAs having the same AID and thus using the same key index. This resulted in one STA overwriting the key information of another STA.

Hence, introduce a new method rt2x00queue_get_tx_queue that is only valid for tx queues and use it in places where only tx queues are valid. Furthermore, this new method is quite short and as such can be inlined to avoid the function call overhead.
