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.

68127a3100 net: gptp: Initial GrandMaster capability support
Implements GMCAP-1, GMCAP-2, and GMCAP-3 and their dependencies from
802.1AS-2011. See Annex A.10 for more details.

The Grand Master Capability can be turned on and off through KConfig.

Note: the correction field in FUP packets is not yet properly
calculated. There is a TODO left in the code, near which some parameters
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
field should be calculated and set properly.

792dfd4a04 net: gptp: Convert SyncReceiptTime to ExtendedTimestamp
SyncReceiptTime should use an ExtendedTimestamp (with fractional
nanoseconds precision). Add a struct with the definition of the needed

The struct representing the ExtendedTimestamp is named
net_ptp_extended_time to keep consistency with the existing net_ptp_time
which is used for regular PTP timestamps.

c21b0fb357 net: sockets: Add a socket offload module
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.

598276262c net: l2: Add support for Link Layer Discovery Protocol (LLDP)
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).

db577f00b1 net: buf: add linearize, append_bytes and skip APIs to net_buf
This change moves the logic for linearize and append_bytes from
the net_pkt sources into the net_buf sources where it can be
made available to layers which to not depend on net_pkt.  It also,
adds a new net_buf_skip() function which can be used to iterated
through a list of net_buf (freeing the buffers as it goes).

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
(this was an addition from the code moved from net_pkt).

In order to preserve existing callers, the original functions are
left in the net_pkt layer, but now merely act as wrappers.

805e2f2c79 net: eth: mgmt: Merge 802.1Qav related mgmt requests
There are too many individual requests for Qav related parameters. There
are more Qav parameters that need to be supported (and will be supported
soon - both on the GET and SET side). Handling it the way it was handled
so far would render the eth mgmt API dominated by Qav parameters. That
would make the file hard to read and understand.

Instead of that - use a single GET and SET requests for all Qav
parameters. This works by adding a separate enum with Qav request type
to the ethernet_qav_param struct.

Additionally this approach makes it much easier to document it all since
we now have just a single request and documentation comments in the
ethernet_qav_param struct.
