This series adds support for NFTA_SET_DESC_CONCAT set attribute and
the additional key passed as NFTA_SET_ELEM_KEY_END to denote the
upper bound of a range in a generic way, as suggested by Pablo.
v4: Sync nf_tables.h header, move NFTNL_SET_DESC_CONCAT to avoid
ABI breakage (Pablo Neira Ayuso)
v3: Support for separate "end" key added as 2/2, reworked 1/2 to
use set description data for length of concatenation fields
Stefano Brivio (3):
include: resync nf_tables.h cache copy
set: Add support for NFTA_SET_DESC_CONCAT attributes
set_elem: Introduce support for NFTNL_SET_ELEM_KEY_END

If NFTNL_SET_DESC_CONCAT data is passed, pass that to the kernel
as NFTA_SET_DESC_CONCAT attributes: it describes the length of
single concatenated fields, in bytes.
Similarly, parse NFTA_SET_DESC_CONCAT attributes if received
from the kernel.
This is the libnftnl counterpart for nftables patch:
src: Add support for NFTNL_SET_DESC_CONCAT
v4:
- move NFTNL_SET_DESC_CONCAT to the end of enum nftnl_set_attr
to avoid ABI breakage (Pablo Neira Ayuso)
v3:
- use NFTNL_SET_DESC_CONCAT and NFTA_SET_DESC_CONCAT instead of a
stand-alone NFTA_SET_SUBKEY attribute (Pablo Neira Ayuso)
- pass field length in bytes instead of bits, fields would get
unnecessarily big otherwise
v2:
- fixed grammar in commit message
- removed copy of array bytes in nftnl_set_nlmsg_build_subkey_payload(),
we're simply passing values to htonl() (Phil Sutter)

The new set element attribute maps to the netlink attribute
NFTA_SET_ELEM_KEY_END in the same way as NFTNL_SET_ELEM_KEY
maps to NFTA_SET_ELEM_KEY, and represents the key data used
to express the upper bound of a range, in concatenations.
