We have embed mode which uses drivers directly. Even though, network driver is currently doesn't work in embed mode. And strictly speaking this was not tied to RPC, the problem was in public API implementation which called the callback with swapped arguments. So any of local drivers (remote driver, ESX, test driver, ...) were affected too, even though it's the remote driver alone that implemented the callback. I'm not objecting to this patch, just trying to shed more light into the problem. Michal
