As a quick test I placed descriptors and the entire pool into non-cacheable SRAM. No further code changes are necessary although it took some time tweaking the linker and lwipopts.h file. I had to shrink it a little to fit into a 64kB section but network communication still seems to be stable. Could this be a solution in order to run uC with cache enabled while keeping lwip code 'almost as is' ?
Following your posts I feel a little overloaded by your input - "zero copy" etc. I understand that I have to do some RTFM and spend some time in the mailing list in order to do something that makes _really_ sense. The next step would be to upgrade to 2.0.3 I guess.
