2010-05-10rt2x00: Clean up all driver's kick_tx_queue callback functions.Gertjan van Wingerde
All of the driver's kick_tx_queue callback functions treat the TX queue for beacons in a special manner. Clean this up by integrating the kicking of the beacon queue into the write_beacon callback function, and let the generic code no longer call the kick_tx_queue callback function when updating the beacon.

2010-05-07rt2x00: rt2800: use correct txop value in tx descriptorHelmut Schaa
rt2800 devices use a different enumeration to specify what IFS values should be used on frame transmission compared to the other rt2x00 devices. Hence, create a new enum called txop that contains the valid values. Furthermore use the appropriate txop values as found in the ralink drivers: - TXOP_BACKOFF for management frames - TXOP_SIFS for subsequent fragments in a burst - TXOP_HTTXOP for all data frames Signed-off-by: Helmut Schaa <helmut.schaa@googlemail.com> Acked-by: Ivo van Doorn <IvDoorn@gmail.com> Acked-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.

2010-04-16rt2x00: rt2800pci: fix tx path by not accessing the skb after it was DMA mappedHelmut Schaa
rt2800pci used the callback write_tx_desc to write the tx descriptor but also to update the txwi which is part of the dma mapped skb. Since the memory was already DMA mapped _before_ the call to write_tx_desc the device didn't get the txwi data at all or only sporadically. The call order is basically as follows (from rt2x00queue.c): 1) write_tx_data 2) rt2x00queue_map_txskb 3) write_tx_desc Hence, we shouldn't touch the skb in write_tx_desc anymore. To fix this issue create a new rt2800pci_write_tx_data callback and use it for updating the txwi _before_ the memory gets DMA mapped. The tx descriptor is still written (as before) in write_tx_desc. This patch allows basic TX on an rt305x soc device but I'm pretty sure that it will fix pci based cards as well. I can associate just fine with an AP now but I wasn't able to get a wpa secured connection working yet.

Support for rt30xx- and rt35xx-based devices is currently not functional in rt2800pci and rt2800usb. In order to not confuse users we shouldn't claim the PCI and USB device ID's for these devices. However, to allow for testing it is good to still have them available, although disabled by default. Make support for these device configuration options that default to off. For rt2800usb a 3rd class of devices is added, which are the unknown devices. For these devices it is known that they are either based on rt28xx, rt30xx or rt35xx, but it is not known on what chipset exactly. These devices are disabled by default as well, until it can be established on what chipset exactly they are based. Signed-off-by: Gertjan van Wingerde <gwingerde@gmail.com> Signed-off-by: John W.
