75f77db432 include: misc: util.h: Rename min/max to MIN/MAX
There are issues using lowercase min and max macros when compiling a C++
application with a third-party toolchain such as GNU ARM Embedded when
using some STL headers i.e. <chrono>.

This is because there are actual C++ functions called min and max
defined in some of the STL headers and these macros interfere with them.
By changing the macros to UPPERCASE, which is consistent with almost all
other pre-processor macros this naming conflict is avoided.

All files that use these macros have been updated.

e1757277ae net: lldp: Implement LLDP RX API
Add RX API to LLDP. Caller should register callback which is called
from ethernet_recv().

Fixes #9407

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).

Fixes #3233
