Mid frame AXIS pausing+backpressuring

[OCElephant]

From my understanding, it is not possible to pause the transmission of data mid frame (deassert tvalid in the middle of transmitting an axis frame) with AxiStreamSource. Likewise for AxiStreamSink, I haven't found a way to exert backpressure mid frame.

I have tried the set_pause_generator() function to pause transmission and exert back pressure (for source and sink respectively), however this only seems to pause between frames.

Is mid frame pausing/backpressuring possible? Thanks.

So, this should be possible, but I think I just found a bug in how the pausing is handled that results in incorrect behavior under certain conditions. It's possible that you ran in to this bug; I'll get it fixed soon.
