Allow larger fraction of CPU to be used by netlink

Browse Source 
Instead of doing BATCH_DELAY_MS work and BATCH_DELAY_MS sleep, add
a BATCH_WORK_MS (40) and lower BATCH_DELAY_MS (10), so we'll work
80% of the time, and consume netlink messages 20% of the time.

Also raise the total batch size to 8K because on my test machine
we run 2K in 13ms or 8K in ~50ms.
