This companion flag to NFT_TABLE_F_OWNER requests the kernel to keep the
table around after the process has exited. It marks such table as
orphaned (by dropping OWNER flag but keeping PERSIST flag in place),
which opens it for other processes to manipulate. For the sake of
simplicity, PERSIST flag may not be altered though.

Analogous to NFT_MSG_GETOBJ_RESET, but for set elements with a timeout
or attached stateful expressions like counters or quotas - reset them
all at once. Respect a per element timeout value if present to reset the
'expires' value to.

The xt_dccp iptables module supports the matching of DCCP packets based
on the presence or absence of DCCP options.  Extend nft_exthdr to add
this functionality to nftables.

This allows userspace ("nft list hooks") to show which bpf program
is attached to which hook.

Without this, user only knows bpf prog is attached at prio
x, y, z at INPUT and FORWARD, but can't tell which program is where.

applying a per-cgroup policy when processing packets in userspace.
