need to clear arp cache when disable interface,
or it will use the wrong gateway mac address.
Call net_arp_clear_cache function replace to set arp_table 0.

Tomasz Bursztyka 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.

Tomasz Bursztyka 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.

Tomasz Bursztyka 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.

David B. Kinder ac74d8b652 license: Replace Apache boilerplate with SPDX tag
Replace the existing Apache 2.0 boilerplate header with an SPDX tag
throughout the zephyr code tree. This patch was generated via a
script run over the master branch.

Also updated doc/porting/application.rst that had a dependency on
line numbers in a literal include.

Manually updated subsys/logging/sys_log.c that had a malformed
header in the original file.  Also cleanup several cases that already
had a SPDX tag and we either got a duplicate or missed updating.

Jukka Rissanen 53caa13652 net: Refactored ARP packet header handling
The ARP packet header contained ethernet header. This is very
confusing so separate the link layer header. Fixed also the
unit tests to run properly.

Jukka Rissanen 4f193e5baf net: Refactor various network init functions
There is no need to check if the sub-system is initialized
because net_init() is the only place that will call these
functions.
