CoAP library is migrated to support over socket based
applications or other higher layer protocols. Most of the
API's and functionality is kept as it is except few changes.
net_pkt/net_buf is removed from CoAP library. Now it expects
a pre-allocated flat buffer and length. If there is not enough
space to append any data, library simply returns an error.
It's user's responsibility to allocate and free memory.
One change in functionality is, earlier coap_pending_clear()
used to clear the memory, but now it's user's responsibility
to free the memory.

If we receive an IPv4 that has broadcast destination address, then
properly handle it.
This means that for
* ICMPv4, if CONFIG_NET_ICMPV4_ACCEPT_BROADCAST is set (this is the
default value) and we receive echo-request then accept the packet.
Drop other ICMPv4 packets.
* TCP, drop the packet
* UDP, accept the packet if the destination address is the broadcast
address 255.255.255.255 or the subnet broadcast address.
Drop the packet if the packets broadcast address is not in our
configured subnet.
In sending side, make sure that we do not route broadcast address
IPv4 packets back to us. Also set Ethernet MAC destination address
properly if destination IPv4 address is broadcast one.

Note: the correction field in FUP packets is not yet properly

are zeroed to make the correction field be set to 0. This mimics the
behavior of openAvnu (a Linux gPTP client). For full compliance the

SyncReceiptTime should use an ExtendedTimestamp (with fractional
nanoseconds precision). Add a struct with the definition of the needed

which is used for regular PTP timestamps.

This patch enables BSD socket offload to a dedicated
TCP/IP offload engine.
This provides a simpler, more direct mechanism than going
through NET_OFFLOAD (zsock -> net_context -> socket conversions)
for those devices which provide complete TCP/IP offload at the
BSD socket level, and whose use cases do not require
IP routing between multiple network interfaces.
To use, configure CONFIG_NET_SOCKETS_OFFLOAD=y, and register
socket_offload_ops with this module.
