Hi,

The project goal is to implement RPS/RFS on FreeBSD. RPS solves the problem of
mono-queue NIC which can't distribute packets across multiple
processors. RFS is
the extension of RPS, which deliver packets to the CPU where
application running.
This week status:

* Implements RFS
I implemented RFS, but it is only working when sysctrl parameter is
configured belows:
- net.isr.threadnum:[number of CPUs]
- net.isr.bindthreads:[1]

It is necessary to net.isr.threadnum is flexible.

next wee:
* Enable changing net.isr.threadnum
