Hi, We consider using a MPC8275 running Embedded Linux to route two 100MB/s Ethernet links in software. The traffic will mostly be incoming on the two FE links and outgoing on the PCI bus, which is connected to a gigabit routing chip (can't connect the two FE links to the routing chip directly, since it only has GE ports).
My question is: Will the MPC8275 be able to handle 2xFE full speed? Doing the calculations about bus speeds etc, it looks ok, but I know Linux does not like high interrupt rates. Is there a rule of thumb about what's the maximum recommended interrupt rate at a given clock speed? Hope to hear from you, Regards Jostein Pettersen -------------- next part -------------- An HTML attachment was scrubbed...
