netfilter: ipv6: add IPSKB_REROUTED exclusion to NF_HOOK/POSTROUTING invocation
Similar to how IPv4's ip_output.c works, have ip6_output also check the IPSKB_REROUTED flag. It will be set from xt_TEE for cloned packets since Xtables can currently only deal with a single packet in flight at a time. Signed-off-by: Jan Engelhardt <jengelh@medozas.de> Acked-by: David S. Miller <davem@davemloft.net> [Patrick: changed to use an IP6SKB value instead of IPSKB] Signed-off-by: Patrick McHardy <kaber@trash.net>
