Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net: 1) Extend nf_queue selftest to cover re-queueing, non-gso mode and delayed queueing, from Florian Westphal. 2) Clear skb->tstamp in IPVS forwarding path, from Julian Anastasov. 3) Provide netlink extended error reporting for EEXIST case. 4) Missing VLAN offload tag and proto in log target. ==================== Signed-off-by: Jakub Kicinski <kuba@kernel.org>
