Actually, we've hand-rolled 'ratecheck()'. Would you like to modify your code to use ppsratecheck() instead? That'd make this all much easier.

sys/net/rss_config.h

Use ppsratecheck() here and a global rate limit timeval for RSS.

Sure!

Use ppsratelimit() for doing message rate limiting and and a global rate limit (maxpps, ie. the 3rd parameter of ppsratelimit()) for RSS.

I'm okay with this, we can replace it with SDT stuff when it's ready.
