>From a quick look it seems at least IPv4 and IPv6 don't need to change the skb anywhere else. It seems to be necessary for bridging though to unshare the skb. OTOH br_netfilter.c already unshares the skb for IPv4 and IPv6, so we could simply do this unconditionally before calling the hooks. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
