Where it makes entirely sense for it to send the logs through its own

So enabling the new API to manage that. That has to be used with

allocate buffer. Basically, only net_context will uses that scheme

Initial implementation of IPSO Timer object #3340
Based on: http://www.openmobilealliance.org/tech/profiles/lwm2m/3340.xml
"This IPSO object is used to time events and actions, using patterns
common to industrial timers. A POST to the trigger resource or On/Off
input state change starts the timing operation, and the timer
remaining time shows zero when the operation is complete. The
patterns supported are One-Shot (mode 1), On-Time or Interval
(mode 2), Time delay on pick-up or TDPU (tmode 3), and Time Delay
on Drop-Out or TDDO (mode 4). Mode 0 disables the timer, so the output
follows the input with no delay. A counter is provided to count
occurrences of the timer output changing from 0 to 1. Writing a value
of zero resets the counter. The Digital Input State resource reports
the state of the timer output."

made by ethernet_send after the packet has been given to the driver.
We fix this by using an atomic_t to hold the reference count as there
might be other, difficult to find cases of net_pkt_(un)ref being used
across threads and interrupts.
The name of the element has been changed from "ref" to "atomic_ref" to
cause a compile error when code still has not been converted to use the

As `addr_type` field already holds different kind of information

When offloading is enabled, a call to inet_pton() results in a call to
zsock_inet_pton() based on its implementation in include/net/socket.h.
This eventually leads to a call to _impl_zsock_inet_pton(), which is
not defined when offloading is enabled.
In this commit, we have chosen to directly call net_addr_pton() in
inet_pton() in the offload case to be efficient, and keep the
implementation as it is when offload is not enabled.

net_frag_linearize() is just a wrapper for net_buf_linearize(). As

return actual copied length, update the former and its usages too.

Don't try to find "errors" in the values of dst_len and len params
passed to net_buf_linearize(). Instead, do what entails with the
common sense from the values passed in, specifically:
1. Never read more than dst_len (or it would lead to buffer
overflow).
2. It's absolutely ok to read than specified by "len" param, that's
why this function returns number of bytes read in the first place.
The motivation for this change is that it's not useful with its
current behavior. For example, a number of Ethernet drivers linearize
a packet to send, but each does it with its own duplicated adhoc
routine, because net_buf_linearize() would just return error for the
natural use of:
net_buf_linearize(buf, sizeof(buf), pkt->frags, 0, sizeof(buf));

The net-shell "net allocs" command should print network buffer
allocations even if network packet debugging is not enabled.
This is how it used to work earlier but the behaviour got lost
at some point. So user needs to set CONFIG_NET_DEBUG_NET_PKT_ALLOC
in order to see the buffer allocations. The option will be enabled
by default if network packet log level is set to DBG.
The reason for a separate option is that the network packet debug
logging prints just too much data and it is very difficult to

Current code generating Ethernet header is scattered all over the place,
sometimes in functions that are supposed to check something (and not
filling the header). Not to say about innefficiency.
Src ll address does not need to be set in L2 as net_if.c handles that
already.
Broadcast dst ll address is the same in ipv4 or ipv6, thus factorizing.
In each case, multicast is filled in only at the relevant place.
This is the first step towards changing L2 sending logic, when L2 send
API function will be the only point of sending. The redirection from
driver to L2 again (which finally uses the right device API function to
send) it a temporary hack.
This simplifies the code but will also enable using statically

The LLDP protocol defines 2 separate agents, the Transmitters and
the Receivers. For the context of Zephyr, we are only interested in
the Tx agent, thus we drop any LLDP frames received by Zephyr.
LLDP frames are basically composed by an ethernet header followed by
the LLDP Protocol Data Unit (LLDPDU). The LLDPDU is composed by several
TLVs, some of them being mandatory and some optional.
Our approach here is having TLVs fully configured from Kconfig, thus
having the entire LLDPDU constructed on build time.
The commit adds NET_ETH_PTYPE_LLDP definition and related handling.
If CONFIG_NET_LLDP is enabled then ethernet_context has a pointer to
the struct net_lldpdu that belongs to that ethernet interface. Also
when CONFIG_NET_LLDP is enabled, the LLDP state machine will start to
send packets when network interface is coming up.
Currently the LLDP state machine is just a k_delayed_work() sending the
LLDPDU at a given period (defined by CONFIG_NET_LLDP_TX_INTERVAL).

adds a new net_buf_skip() function which can be used to iterated

For the append_bytes function to be generic in nature, a net_buf
allocator callback was created. Callers of append_bytes pass in
the callback which determines where the resulting net_buf is
allocated from.
Also, the dst buffer in linearize is now cleared prior to copy
