====================
Netfilter fixes for net

The following patchset contains Netfilter fixes for your net tree,
they are:

1) Don't pick fixed hash implementation for NFT_SET_EVAL sets, otherwise
   userspace hits EOPNOTSUPP with valid rules using the meter statement,
   from Florian Westphal.

2) If you send a batch that flushes the existing ruleset (that contains
   a NAT chain) and the new ruleset definition comes with a new NAT
   chain, don't bogusly hit EBUSY. Also from Florian.

3) Missing netlink policy attribute validation, from Florian.

4) Detach conntrack template from skbuff if IP_NODEFRAG is set on,
   from Paolo Abeni.

5) Cache device names in flowtable object, otherwise we may end up
   walking over devices going aways given no rtnl_lock is held.

6) Fix incorrect net_device ingress with ingress hooks.

7) Fix crash when trying to read more data than available in UDP
   packets from the nf_socket infrastructure, from Subash.
