Schedule tasklet with high priority to ensure that callback processing
is prioritized. It improves throughput for netdev dma clients.

Do you have specific numbers on the throughput improvement?

IIRC there was ~5% performance improvement but I did that a long back
on an older kernel 4.8 and after that onward I always checked overall
performance (having all optimization applied). In next version i will 
redo incremental profiling and capture improvement % in the commit 
description.

Thanks,
