21d6e302f6 net: lwm2m: Fix warning when building with newlib
If we use newlib the isdigit (and other similar functions) return an
error as char can possibly be viewed as signed:

usr/include/ctype.h:57:54: error: array subscript has type ‘char’ [-Werror=char-subscripts]
 #define __ctype_lookup(__c) ((__ctype_ptr__+sizeof(""[__c]))[(int)(__c)])

Explicity cast to unsigned char so we deal with both this warning and
possible warning when -Wpointer-sign is enabled.

cb00061cbe net: dhcpv4: Use less parameters in debug print
Having 24 parameters in a debug print is a bit extreme especially
as it is causing warning from new logger. Split the debug print
to three pieces each having 8 parameters which is more reasonable.

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.

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.

35a7804cdf net/arp: Centralize ARP request timeout through one k_delayed_work
Until now, each ARP entry had a k_delayed_work to be used as a timer
when the ARP entry is a pending one, waiting for the ARP request to
succeed in order to get to the ARP table.

But k_delayed_work is not a small object (40 bytes). Thus reworking the
ARP request timer by having one central k_delayed_work and a timestamp
in every ARP entry properly handled at every timeout (1+ entry might
have reached the timeout then).
