UDP/IP via Ethernet in real time (config-preempt patch)

[M. Koehrer]

Hi everybody,

I have a question concerning Ingo Molnar's realtime preempt patch.
This patch is great go get low latency on timer threads and a really
good real time behaviour.
I want to connect an external, embedded device via Ethernet (UDP/IP) 
to my Linux PC. This communication should be in real time as well.
For this I have a separate network adapter in my PC that is used
solely for this UDP Ethernet traffic.
However, I think all Ethernet traffic is be handled by
the soft IRQ threads [softirq-net-rx] [softirq-net-tx] but I do
not see a way to do real time networking via one of the network adapters.

How can I get this UDP networking real time capable?

Any feedback is welcome.

Thanks a lot!

Regards

Mathias
