Would you like to > hack the kernel code and rebuild just for peek the dropping packets ? Search 'dropwatch' on your favorite engine search. That is a pretty good tool to trace and debug protocal stack when packet dropping happens. but it is more professional and specific to kernel kallsyms, has some bugs to work well on my box. yet another different tool to output debug info while not statistic info. I think drivers output rx dropped has their own reason. [...] > More radically, and maybe you should write patches to fix them to keep > their focus. That is to prove you have principle and always fight for it. It's 15 years late but it's still a good advice. :o) Does it work ?
