Go enjoy your vacation, I can handle this :) I think you arrived at kernel 3.14 due to 8f84985fec10d. However, I think we can just do the following * backport "struct pcpu_sw_netstats" (needed on < 3.14) * backport "netdev_alloc_pcpu_stats" (needed on < 3.15) * make an spatch replacing dev->tstats with ((struct pcpu_sw_netstats *)dev->ml_priv) (since ml_priv has existed for a long time, and they're in a union) johannes -- To unsubscribe from this list: send the line "unsubscribe backports" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
