Or - at least for the bnx2x, it is easy to add support for this new ndo.Do you understand what's the equivalent of that mysterious module param for your driver/HW - or you just copied and pasted that black magic code?
The module parameter is not the interesting part of this patch. It is clear that unloading the module while this sort of traffic is running is not safe and the alternative of adding a reference count or something similar sounds too costly (after all, this patch is about performance). I just played with it to get a feel of the latency improvement - I did not try unloading the module during traffic so I do not care about the module parameter part right now. I agree that the unload should be looked into - but the general concept is great and it is a very nice improvement. ------------------------------------------------------------------------------ Try New Relic Now & We'll Send You this Cool Shirt New Relic is the only SaaS-based application performance monitoring service that delivers powerful full stack analytics.
