Hi,
I have tried to build and debug the single thread packet receiving and counting
program from the IXP1200 book in simulation mode. But I could not debug it
successfully because the simulation halts giving an error:" FBUS logic-
unexpected encoding on incoming byte enables:ff ". Debugging stops at the
"ctx_receive(start_receive)" line in the get_mpacket() function.
Does anybody have any idea to help me in this regard?
Thanks.

Hi,
I have carried out some testing on a single thread process receiving and counting packets (code from chapter 5 from ixp 1200 book) When it runs at wire speed at 177Mhz and Ixbus at 66 Mhz it has a receive rate of 350 Mbps at the IX bus. The same rate is achieved when running at 200Mhz, Ixbus at 66Mhz. I would expect the receive rate to be faster.
Does anyone have any idea as to why the receive rate isn't higher for 200MHZ?
