Hmm, I didn't spot any case where you'd pass NULL, but maybe I didn't
search hard enough. Is this for patchs in this set or in a future
set ? If it's in the current set, do you have an example where this
check is needed ?

This may be misunderstood. When I read it, my first question was in
which other patch you defined MAC802154_FRAME_HARD_HEADER_LEN. But
of course, it already exists. So I'd say something l
This patch fixes the fragmentation on sending side according to rfc4944.
Also add improvemnt to use the full payload of a PDU which calculate the
nearest divided to 8 payload length for the fragmentation datagram
offset attribute.

This will add support to skip bytes from skb with the lowpan_fetch_skb
function.

This patch fixes the fragmentation of receiving 6lowpan packets.
The current fragmentation isn't rfc4944 compatible.
Add support for fragmentation frame match with source and destination
addresses, instead of using tag id of fragmentation header only.

Set the mac header length while creating the 802.15.4 mac header.
Drop the function for recalculate mac header length in upper layers
which was static and works for intra pan communication only.

The current implementation does many copies of the sk_buff for
increasing headroom which are not necessary.
This patch increases the headroom in the maclayer for a worst case
scenario of (sizeof(struct ipv6hdr) + sizeof(struct udphdr)).

This patch removes some magic number.
Instead of magic numbers we use some defines.

The current udp compression/uncompression have several issues.
A list of founded issues:
1. Byteordering issues in both functions which indicate that these functions
never worked correctly.
2. Fixing derefecening issue which occurs a deferencing nullpointer
sometimes.
3. Compress source p
This patch series fixes the fragmentation implementation according to rfc4944.
So ping (with fragmentation) to contiki(or other rfc4944 compatible 6lowpan
stacks) comes possible.
I wanted to made a fragmentation implementation with the internal fragmentation
