This will simplify the new reassembly backport
with no code changes being required.

Fragmentation and reassembly information for 6lowpan is independent from
the 802.15.4 stack and used only by the 6lowpan reassembly process. Move
the ieee802154_frag_info struct to a private are, it needn't be in the
802.15.4 skb control block.

Change all internal uses of ieee802154_addr_sa to ieee802154_addr,
except for those instances that communicate directly with userspace.

The struct as currently defined uses host byte order for some fields,
and most big endian/EUI display byte order for other fields. Inside the
stack, endianness should ideally match network byte order where possible
to minimize the number of byteswaps done in critical paths, but this
patch does not address this; it is only preparatory.

most of these are only used locally, make them static.
fold lowpan_expire_frag_queue into its caller, its small enough.

Correct offset is 3 of the 6lowpanfrag_max_datagram_size value in proc
entry ctl table and not 2.

This patch adds a missing return after fragmentation init. Otherwise we
register a sysctl interface and deregister it afterwards which makes no
sense.

This header is used by bluetooth and ieee802154 branch. This patch
move this header to the include/net directory to avoid a use of a
relative path in include.

Datagram size value is u16 because we convert it to host byte order
and we need to read it. Only the tag value belongs to __be16 type.

This patch drops the current way of 6lowpan fragmentation on receiving
side and replace it with a implementation which use the inet_frag api.
The old fragmentation handling has some race conditions and isn't
rfc4944 compatible. Also adding support to match fragments on
destination address, source address, tag value and datagram_size
which is missing in the current implementation.
