Hello, this PR contains updates for your *net-next* tree. nftables updates: 1. Allow key existence checks with maps. At the moment the kernel requires userspace to pass a destination register for the associated value, make this optional so userspace can query if the key exists, just like with normal sets. 2. nftables maintains a counter per set that holds the number of elements. This counter gets decremented on element removal, but its only incremented if the set has a upper maximum value. Increment unconditionally, this will allow us to update the maximum value later on. 3. At DCCP option maching, from Jeremy Sowden. 4. use struct_size macro, from Christophe JAILLET. Conntrack: 5. Squash holes in struct nf_conntrack_expect, also Christophe JAILLET. 6. Allow clash resolution for GRE Protocol to avoid a packet drop, from Faicker Mo. Flowtable: Simplify route logic and split large functions into smaller chunks, from Pablo Neira Ayuso.
