Try to catch the original caller of setup_gptp_frame() function
in order to see who is allocating buffers.

Jukka Rissanen e21d7cc72d net: gptp: Refactor the gPTP header addition
Increase the net_buf length in proper places. So when gPTP
header is added, increase the buf->len properly, and then
when gPTP packet type is added, increase it again properly.
This way the net_buf length is updated in more logical way.

Jukka Rissanen 83f38b5f2d net: gptp: Remove log_strdup() when printing packet info
As the msg parameter for PRINT_INFO() is always a const string
that is not coming from stack, there is no need to use
log_strdup() here. This helps to avoid the
"<log_strdup alloc failed>" messages.

If the link layer header is in the separate net_buf,
then skip that one.

Jukka Rissanen 86689030e8 net: Clarify logging in networking code
Remove network specific default and max log level setting
and start to use the zephyr logging values for those.

Remove LOG_MODULE_REGISTER() from net_core.h and place the
calls into .c files. This is done in order to avoid weird
compiler errors in some cases and to make the code look similar
as other subsystems.

Fixes #11343
Fixes #11659

Jukka Rissanen 57a8db7789 net: Use log_strdup() when printing debug strings
As the debugging print calls are async, all the strings that might
be overwritten must use log_strdup() which will create a copy
of the printable string.

Jukka Rissanen 15e7e3ea4b net: ip: Split debug prints into smaller pieces
Currently logging subsystem supports quite small number of function
parameters. So split some long functions into smaller pieces.
Hopefully this is just a temporary patch and we can support more
parameters to logging macros.

Jukka Rissanen a76814bfb6 net: Convert core IP stack to use log levels
Instead of one global log level option and one on/off boolean
config option / module, this commit creates one log level option
for each module. This simplifies the logging as it is now possible
to enable different level of debugging output for each network
module individually.

The commit also converts the code to use the new logger
instead of the old sys_log.

Tomasz Gorochowik 2ca3b1e3c4 net: if: Fix TX timestamp callbacks invocation
The problem is that net_if_call_timestamp_cb only checked if the
callback was registered for the PORT which invoked the whole action.

There is a possibility, that the callback will be registered, and packet
A will be passed to eth driver. Before the driver is finished with
packet A, network layer will start handling another packet (B) - so it
will unregister the callback for packet A and register it for B. After
that the network driver will finish processing packet A and invoke the
timestamp callback. The mechanism would then only check if a callback is
registered for the port of the driver and invoke the callback for the
packet that was registered earlier (so A instead of B).

This commit fixes that by storing info not only about the port but about
the packet too.

Jukka Rissanen f3146c09ab net: gptp: Fix buf leak in PDELAY_REQ send
Do not clear pending PDELAY_REQ pointer when sending a new one.
Unref the state->tx_pdelay_req_ptr first and only then set the
new pointer value. This will prevent buffer leak if we miss the
response from the peer.

Tomasz Gorochowik 7e545c998c net: gptp: Do not handle multiple pdelay requests at once
The problem with the previous approach was that the response timestamp
callback which calls net_pkt_unref could be skipped if the callback was
already registered for another packet. The net_pkt_ref function was
always called which led to memory leaks.

This commit simply disallows handling multiple pdelay requests at once.
If the timestamp callback is already registered, the received request
will not be handled.
