Both ETHERNET_HW_TX_CHKSUM_OFFLOAD and ETHERNET_HW_RX_CHKSUM_OFFLOAD
apply to all of IPv4, UDP, and TCP heafers (there's no checksum in
IPv6 header). Consequently, these options should be enabled only for
hardware which supports offloading for all of these options. (And
hardware which has fine-grained control over individual protocol
headers, should enable them all).
Based on the handling in the current source code and discussion
in #21269.

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
allocated net_buf and ethernet header payload buffer afterwards.

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).

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.
