Got it, thanks. I'll remove them in v3 or, in case v2 gets accepted, will send a follow-up patch(es) for removing redundant Ethtool stats. > Side question: what does "nch" stand for? "The number of channels". I was thinking of an intuitial, but short term, as get_xdp_stats_channels is too long and breaks Tab aligment of tons of net_device_ops across the tree. It was "nqs" /number of queues/ previously, but we usually use term "queue" referring to one-direction ring, in case of these stats and XDP in general "queue pair" or simply "channel" is more correct.
