f3ff4f7bd3 net_pkt: Let's make all IPv6 related attributes prefixed with ipv6_
Only 2 attributes lacked this prefix, which makes sense to have, so
applying it accordingly and changing the helpers as well.

e5896906f6 net: Rename all *_BUF() macros to *_HDR()
Most of these macros are not exactly exposing a buffer, but a specific
header pointer (ipv6, ivp4, ethernet and so on), so it relevant to
rename them accordingly.

02cb7e6e71 net_pkt: Reordering the attributes for better alignment
Instead of using a bool, let's just use a bit in a bifield, shared among
various attribute. This saves space.

Make ext_len attribute enabled only on IPv6 (ipv6, icmpv6 and rpl are
the only code setting it) and reordering the helpers functions
accordingly.

c18016b69b net_pkt: Externalize ext_bitmap handling
IPv6 next headers are processed in a way so it is not required to store
which header has been already seen in the net_pkt, as the processing loop
can store internally which one it has seen already.

db11fcd174 net/net_pkt: Fully separate struct net_pkt from struct net_buf
- net_pkt becomes a stand-alone structure with network packet meta
  information.
- network packet data is still managed through net_buf, mostly named
  'frag'.
- net_pkt memory management is done through k_mem_slab
- function got introduced or relevantly renamed to target eithe net_pkt
  or net_buf fragments.
- net_buf's sent_list ends up in net_pkt now, and thus helps to save
  memory when TCP is enabled.

bf964cdd4c net: Renaming net nbuf API to net pkt API
There have been long lasting confusion between net_buf and net_nbuf.
While the first is actually a buffer, the second one is not. It's a
network buffer descriptor. More precisely it provides meta data about a
network packet, and holds the chain of buffer fragments made of net_buf.

Thus renaming net_nbuf to net_pkt and all names around it as well
(function, Kconfig option, ..).

Though net_pkt if the new name, it still inherit its logic from net_buf.
'
This patch is the first of a serie that will separate completely net_pkt
from net_buf.

789081673f Introduce new sized integer typedefs
This is a start to move away from the C99 {u}int{8,16,32,64}_t types to
Zephyr defined u{8,16,32,64}_t and s{8,16,32,64}_t.  This allows Zephyr
to define the sized types in a consistent manor across all the
architectures we support and not conflict with what various compilers
and libc might do with regards to the C99 types.

We introduce <zephyr/types.h> as part of this and have it include
<stdint.h> for now until we transition all the code away from the C99
types.

We go with u{8,16,32,64}_t and s{8,16,32,64}_t as there are some
existing variables defined u8 & u16 as well as to be consistent with
Zephyr naming conventions.

d6d1b3a748 net/mgmt: Add a network interface based synchronous event listener
In case of callback based event listener, it is easy for the callback to
filter on the given interface. But in case of the synchronous call it's
not: it would need, after a failed comparison on the interface pointer
to loop by itself on the net_mgmt_event_wait() which is a little bit
heavy (reinstalling the event listener, with the semaphore and all) and
a bit of a burden for the caller itself.

Instead, net_mgmt provides a dedicated call
net_mgmt_event_wait_on_iface() which does it the right way, so the
callback and the related semaphore are destroyed if only the iface
matches the one given as parameter (besides the timeout obviously).

e38a9e8b9c net: Switch from per-iface tx thread to a unique k_poll triggered one
Now that k_poll landed in the kernel, it's worth using it to save
memory and reduce the number of threads at runtime.

Such switch has been first done in bluetooth (see hci_core.c and conn.c
in subsys/bluetooth/host). Since network interfaces kind of follows the
same design for sending data, it was then easy to copy the same change as
in bluetooth.
