Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Pablo Neira Ayuso says: ==================== Netfilter updates for net-next The following patchset contains Netfilter updates for net-next: 1) Use nf_flow_offload_tuple() to fetch flow stats, from Paul Blakey. 2) Add new xt_IDLETIMER hard mode, from Manoj Basapathi. Follow up patch to clean up this new mode, from Dan Carpenter. 3) Add support for geneve tunnel options, from Xin Long. 4) Make sets built-in and remove modular infrastructure for sets, from Florian Westphal. 5) Remove unused TEMPLATE_NULLS_VAL, from Li RongQing. 6) Statify nft_pipapo_get, from Chen Wandun. 7) Use C99 flexible-array member, from Gustavo A. R. Silva. 8) More descriptive variable names for bitwise, from Jeremy Sowden. 9) Four patches to add tunnel device hardware offload to the flowtable infrastructure, from wenxu. 10) pipapo set supports for 8-bit grouping, from Stefano Brivio. 11) pipapo can switch between nibble and byte grouping, also from Stefano. 12) Add AVX2 vectorized version of pipapo, from Stefano Brivio. 13) Update pipapo to be use it for single ranges, from Stefano. 14) Add stateful expression support to elements via control plane, eg. counter per element. 15) Re-visit sysctls in unprivileged namespaces, from Florian Westphal. 15) Add new egress hook, from Lukas Wunner. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
