| | | | | | | | | | | This moves mac80211 documentation into a new 802.11 bookset and also adds a cfg80211 book to the set.

* p54: improve eeprom parserChristian Lamparter2010-08-242-3/+19
| | | | | | | | | | | | | | | | | | | | Like other vendors, p54* devices have a checksum for the EEPROM descriptor data. This patch enhances the parser code to generate and verify the data fields, before initializing the radio-chip on the card. Note: If you have to bootstrap an alternative EEPROM image for your device and you don't know how to generate a valid crc ccitt checksum, you should take a look at: http://git.kernel.org/?p=linux/kernel/git/chr/p54tools.git The "checksum" utility loads a binary p54 EEPROM blob (use the -f switch, to skip the check) and applies the correct crc automatically.

* rt2x00: Remove ieee80211_rx_status from rt2x00_devIvo van Doorn2010-08-166-20/+16
| | | | | | | | | | | | | | | | rt2x00 was keeping a copy of ieee80211_rx_status embedded into the rt2x00_dev structure. For each RX frame, this structure was copied into the skb->cb where mac80211 would handle it further. However at the moment only the fields current band, and frequency were updated. Whereas the band was already provided directly within the rt2x00_dev structure. Save a memcpy action, and reduce memory a bit, by adding a curr_freq field to rt2x00_dev, and completely remove the ieee80211_rx_status structure from rt2x00_dev.

| | | | | | | | | | | | | | | | | | The TX_STA_FIFO register which is used for per-frame TX frame status reporting is also valid on rt2800usb. We can move the rt2800pci_txdone function into rt2800lib where it can also be used by rt2800usb. rt2800usb needs to overwrite the txdone work handler to a different function. Both rt2800usb as rt2800_txdone need to take into account that IO failures can occur while uploading the URB, which means that when obtaining the new entry the IO status must be checked.

* rt2x00: Request TXWI pointer from driverIvo van Doorn2010-08-164-18/+26
| | | | | | | | | | | | | | | | | The only reason why the write_tx_data callback function is needed inside the driver, is because the location of the TXWI descriptor is different on PCI and USB hardware. Except for the beacon, where the TXWI is always at the start of the SKB buffer. In both cases the drivers write_tx_data function only wrap around the function rt2800_write_txwi. Move write_tx_data completely into the rt2800lib library, and add a callback function to obtain the TXWI pointer.

* rt2x00: Move USB tx/rx done handling to workqueueIvo van Doorn2010-08-165-62/+128
| | | | | | | | | | | | | | | | | | | | | Move all TX and RX completion handling into a work structure, which is handeled on the mac80211 workqueue. This simplifies the code in rt2x00lib since it no longer needs to check if the device is USB or PCI to decide which mac80211 function should be used. In the watchdog some changes are needed since it can no longer rely on the TX completion function to be run while looping through the entries. (Both functions now work on the same workqueue, so this would deadlock). So the watchdog now waits for the URB to return, and handle the TX status report directly. As a side-effect, the debugfs entry for the RX queue now correctly displays the positions of the INDEX and INDEX_DONE counters. This also implies that it is not possible to perform checks like queue_empty() and queue_full() on the RX queue. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* mac80211: AMPDU rx reorder timeout timerChristian Lamparter2010-08-164-12/+97
| | | | | | | | | | | | | | | | | | | | | This patch introduces a new timer, which will release queued-up MPDUs from the reorder buffer, whenever they've waited for more than HT_RX_REORDER_BUF_TIMEOUT (which is at around 100 ms). The advantage of having a dedicated timer, instead of relying on a constant stream of freshly arriving aMPDUs to release the old ones, is particularly observable when even a small fraction of MPDUs are forever lost at low network speeds. Previously under these circumstances frames would become stuck in the reorder buffer and the network stack of both HT peers throttled back, instead of revving up and gunning the pipes.
