samples: net: W5500 implementation

[yaadc]

Describe the bug
The W5500 driver documentation looks quite vague, maybe it is just me.
Is there a chance to include a simple example showing how to use the W5500 driver?

Thanks.

@rlubos any advice here?

Converting to discussion

Indeed it seems there is no example usage of this driver, other than a generic Ethernet buildall test, it doesn't also seem to be enabled automatically by any board/shield. That is a pity, I don't have the hardware though to verify the driver and add support to one of the samples. Perhaps the driver author @parthitce could help here?

[parthitce]

Development was done with a custom breakout board and consumed in customer hardware in my end. Do we need specific sample application for ethernet drivers? Is it not all the generic samples under samples/net should work by enabling under Kconfig?

Let me know if it makes sense to add device tree overlay otherwise to nrf52 or frdm kind.

[rlubos]

I didn't mean a specific sample for ethernet driver, but rather enabling the driver in one of the existing samples (zperf for instance) by adding driver-specific configuration to the sample.

Usually, it's not needed, as particular drivers are enabled automatically by selecting the appropriate board/shield - that way the board/shield is responsible for providing a valid configuration for the driver. However in this case, the driver is not associated with any board/shield, so it can't be selected automatically. We'd need an overlay that'd show how to enable the driver in an application.

[parthitce]

I understand. Will add a shield for this breakout board for reference development. Hope that works?

[rlubos]

From my perspective, this should be fine. Thanks!
