If you're asking about $subject (moving NAPI/RX to a thread), this
landed upstream recently:
http://git.kernel.org/linus/adbb4fb028452b1b0488a1a7b66ab856cdf20715

It needs a bit of coaxing to work on a WiFi driver (including: WiFi
drivers tend to have a different netdev for NAPI than they expose to
/sys/class/net/), but it's there.

I'm not sure if people had something else in mind in the stuff you're
quoting though.
