`esp_eth_ioctl(ETH_CMD_S_MAC_ADDR)` sets the MAC address of the hardware
device, but we also need to notify the upper layers of the change so that
e.g. DHCP work properly.
Add support for various SPI-based ethernet chips (W5500, KSZ8851SNL,
DM9051) to the ESP32 port. This leverages the existing support in ESP-IDF
for these chips -- which configures these chips in "MAC raw" mode -- and
the existing support for network.LAN in the ESP32 port. In particular,
this doesn't leverage the wiznet5k support that is used on the rp2 and
stm32 ports (because that's for native use of lwIP).
Tested on the POE Featherwing (with the SJIRQ solder jumper bridged) and a
ESP32-S3 feather.
A note about the interrupt pin: The W5500 implementation within ESP-IDF
relies on hardware interrupt, and requires the interrupt pin from the W5500
to be wired to a GPIO. This is not the case by default on the Adafruit
Ethernet FeatherWing, which makes it not directly compatible with this
implementation.
Both the direction and the Pin used for ref_clk can now be configured. It
Requires at least idf v4.4. The new keyword arguments to the constructor
are:
- ref_clk_mode=mode: with mode being Pin.IN or Pin.OUT. If it is not set,
then the default configuration is used, which may be configured by
kconfig settings.
- ref_clk=pin_obj: which defines the Pin used for ref_clk. This is either
Pin(0), Pin(16) or Pin(17). No check is done for the pin number. If it
is the wrong one, it simply will not work. Besides that, no harm.
LAN8710 uses the same drivers as LAN8720, so this commit just adds the
names. Alternatively, both could be summarised under LAN87xx, like the
esp-idf does.
Instead of being an explicit field, it's now a slot like all the other
methods.
This is a marginal code size improvement because most types have a make_new
(100/138 on PYBV11), however it improves consistency in how types are
declared, removing the special case for make_new.

Ethernet-PHYs from ESP-IDF (LAN8720, IP101, RTL8201, DP83848) are now
supported in IDF v4.1 and above. PHY_KSZ8041 is only for ESP-IDF 4.3 and
above. ESP32S2 is not supported.

Note: the uncrustify configuration is explicitly set to 'add' instead of
'force' in order not to alter the comments which use extra spaces after //
as a means of indenting text for clarity.
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag). When this hash is detected, the relevant changes are
applied.
This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.
Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.
