Hi!

My next hack - adding flowid/flowtype to netstat. It's netstat -R.
It's like -x, but listing RSS/flowid stuff.

http://people.freebsd.org/~adrian/norse/20140518-netstat-rss-1.diff

This is useful for both RSS and non-RSS debugging - NICs that populate
the mbuf flowid will start to show flowid's up in netstat.

It doesn't currently show the rss CPUID as that isn't cached in the
inpcb. I'll worry about adding that later on.

Any issues with me just committing this? I promise I'll email doc@ to
get it documented.

Thanks,


-a
