Hi
This patchset enabled RX packet DMA aggregation, batching multiple
received packets into larger buffers. This should reduce the number of
DMA transactions and the number of USB interrupts due to DMA complete
notifications.
Since this is new code, I am leaving it disabled per default for
now. In order to enable it, a user must set dma_aggregation=1 on
module load.
I'd love to hear feedback from people testing this feature. For those
who wish to compile directly, you can checkout the
rtl8xxxu-aggregation branch of my git tree.
Cheers,
Jes
