2010-06-03rt2x00: Push beacon TX descriptor writing to drivers.Gertjan van Wingerde8-21/+81
Not all the devices require a TX descriptor to be written (i.e. rt2800 device don't require them). Push down the creation of the TX descriptor to the device drivers so that they can decide for themselves whether a TX descriptor is to be created.

This patch removes from drivers/net/ all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that. It also does not remove null void functions with return. Done via: $ grep -rP --include=*.[ch] -l "return;\n}" net/ | \ xargs perl -i -e 'local $/ ; while (<>) { s/\n[ \t\n]+return;\n}/\n}/g; print; }' with some cleanups by hand.

Currently the CCK and OFDM SIFS value is set to 32us. This value is neither used by the Ralink driver nor specified in 802.11. Instead of using 10us for CCK SIFS (as defined in 802.11) use 16us like in the Ralink drivers. And indeed using a SIFS value of 10us breaks connectivity with 11g + CTS protected connections.

To have better control over which values are used for the register initialization create a new function rt2800_is_305x_soc which checks for SoC interface type, the correct RT chipset and the correct RF chipset. This is based on the assumption that all rt305x SoC devices use a rt2872 and rf3020/rf3021/rf3022. In case an unknown RF chipset is found on a SoC device with a rt2872 don't treat it as rt305x and just print a message.

2010-04-16rt2x00: rt2800pci: fix tx path by not accessing the skb after it was DMA mappedHelmut Schaa1-7/+27
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.
