Hi, I am reading the code and trying to understand what forces the packet out of the card, or to be more clear, what runs CSMA/CA and when detects a tx opportunity pushes the packet down to the phy. I can track the packet all the way until it gets to start_tx_dma(), but I am not clear what is the actual call that sends it out, and how this relates with QCU (I am on a 5212). I suspect that it's within the tasklet_schedule but wasn't able to find the details. Also, does QCU get involved on a packet-per-packet basis, or does it just set the initial values to the device's registers? Any help is much appreciated..
