I'm using the Ralink wireless driver with RTnet. I'm sure you know what I'm talking about, it is a realtime UDP/IP networking stack for RTAI/Xenomai frameworks. Real-time drivers are ported from their Linux counterparts with minor modifications. I'm working with it for an experimental graduation thesis and I'm trying to modify the driver code.
I am using a rt2500-based pci card, and I would like to stop the transmission of a packet already copied to the nic's tx buffer, if it exceeds a certain timeout threshold. I have tried to set TXCSR0_ABORT to 1 but this doesn't affect the behaviour.
Can you help me?
