Network buffer fragmentation support

Jukka Rissanen

Hi All,

I just uploaded net_buf fragmentation support to gerrit.

The fragmentation support allows the network stack to use smaller
buffer fragments to support bigger IP buffers. So instead of allocating
full IPv6 buffer (1280 bytes) we can allocate smaller fragments
instead. This is useful as typically network packets are quite small
and always allocating full buffer wastes memory.

This patchset is just an enabler, it does not implement the
fragmentation in the IP stack.

Please review the patchset if this topic interests you.
