Hello, Here is the goal We have general purpose CPU (MIPS with MMU) and a simple network processor - all in one ASIC. Microcode running in the network processor executes lookups according to the packet address/port source/destination, protocol type, MAC address source/destination. Depending on the outcome of the lookup network processor can - drop the packet - forward the packet to one of the interfaces - forward the packet to the CPU Microcode is fairly flexible and can be extended to provide counters of the packets per logical flow, etc. Network processor works with EMAC packets - handles packets containing MAC header. We are running 2.6 Linux kernel in the CPU. Naturally I would like to use netfilter for management of the network processor and use the fast network processor to forward as many packets as possible without CPU intervention. I read through the documentation and started to study the source code. It appears, that it's possible to solve the problem. But I would like to avoid solving the same time problem twice. Is there any example(s) of integration of the network processor and netfilter ? If there is no code any documentation/tips/links could save me lot of time. thank you
