Ethernet::MACAddress() implementation

[d-a-v]

Use Mbed's macAddress() implementation for Arduino MACAddress()

The Mac Address seems to be stable/valid only after ::begin(),
However, I can't explain myself why my Portenta H7's OUI 2B:00:1B cannot be found on the various OUI databases available on internet.

Hi @d-a-v ,
you can already obtain the mac address with Ethernet.macAddress(uint8_t*) method https://github.com/arduino/ArduinoCore-mbed/blob/master/libraries/SocketWrapper/src/SocketHelpers.h#L108
After calling Ethernet.begin() otherwise the phy is not initialized.

The sample code is

#include <PortentaEthernet.h>
#include <Ethernet.h>

void setup() {
  Serial.begin(9600);
  Ethernet.begin();
}

void loop() {
 ....
  uint8_t mac[6];
  Ethernet.macAddress(mac);

  for (int i = 5; i > 0; i--) {
    if (mac[i] < 16) {
      Serial.print("0");
    }
    Serial.print(mac[i], HEX);
    Serial.print(":");
  }
  Serial.println(mac[0], HEX);
  ...
}

On my boards the MAC is in the range 00:80:E1 , which is ST https://hwaddress.com/mac-address-range/00-80-E1-00-00-00/00-80-E1-FF-FF-FF/

[d-a-v]

you can already obtain the mac address with Ethernet.macAddress(uint8_t*)

The purpose of this PR was to use this very method to implement missing code for Ethernet.MACAddress(). On this Arduino API documentation, the official example can be found but it cannot be linked @facchinm.

This pull-request permits to avoid the undefined reference error when one tries to use the official Arduino API.

I assume you missed the fact that this is a pull-request and not an issue, or I missed something else in your closing answer, and would be pleased to be enlightened :)

[facchinm]

Oh well, I thought I knew everything about Ethernet class but I was wrong 🙂 Thanks for pointing it out.
The old MACAddress() method was indeed replaced with macAddress() on all libraries following the original Ethernet one, but since this one is still there and documented I'll keep it (even without adding the deprecated tag)
