The watchdog for rt2800usb triggers frequently causing all URB's to be canceled often enough to interrupt the normal TX flow. More research indicated that not the URB upload to the USB host were hanging, but instead the TX status reports. To correctly detect what is going on, we introduce Q_INDEX_DMA_DONE which is an index counter between Q_INDEX_DONE and Q_INDEX and indicates if the frame has been transfered to the device. This also requires the rt2x00queue timeout functions to be updated to differentiate between a DMA timeout (time between Q_INDEX and Q_INDEX_DMA_DONE timeout) and a STATUS timeout (time between Q_INDEX_DMA_DONE and Q_INDEX_DONE timeout) All Q_INDEX_DMA_DONE code was taken from the RFC from Helmut Schaa <helmut.schaa@googlemail.com> for the implementation for watchdog for rt2800pci.
