You complained on the performance impact of the initial generic hook infrastructure that allows qdisc ingress and nft to co-exist, fair enough. I came back with an even more simple hook infrastructure, to address performance concerns, and you indicate that an *extra dereference and indirect jump* makes this slowier and that both cannot co-exist with this. Well, any kind of hook generalization will need at least those minimal changes. And that allows us to move code that belongs to sch_ingress. That got embedded into net/core/dev.c because at the time this code was made when there was no RCU around. This sounds as an excuse to me. -- To unsubscribe from this list: send the line "unsubscribe netfilter-devel" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
