Well, 10MBit is exactly what Siemens (and the others) claim as maximal
throughput for IP/MPE.  
Beyond that the ARM core goes bye bye ...

Great that you can generate your own streams. That's the first independent
test of the 10MBit limit I heard of.

Hmm, yes, I have to work on the drivers recovering fully after an ARM reset.

I think I found the reason for that.

Somebody still has to write a network module that uses the new API for
filtering.

Sorry, you have to use a different card.
E.g. the Technotrend-Budget/Hauppauge WinTV-Nova can deliver the full
TS and is supported by our driver. But filtering has to be done fully
in software.
