Stopping SGDMA Transfer

But a receive DMA has to be started before any data is available, right? Thus the receive DMA will sit, moving no data, until a packet arrives, right? What if, while the receive DMA is sitting there doing nothing, I want to abort the transfer? It doesn't appear sufficient to simply turn off the RUN bit in the DMA control register, because according to the documentation that only affects descriptors down chain. If, for simplicity sake, I only have one descriptor, turning off RUN doesn't appear to change anything.
