/**
* @brief Derive MAC address.
* @brief Derive local MAC address from universal MAC address.
*
* This function derives a local MAC address from an universal MAC address.
* Addresses can either be universally administered addresses or locally administered addresses.
* A universally administered address is uniquely assigned to a device by its manufacturer.
* The first three octets (in transmission order) identify the organization that issued the identifier
* and are known as the Organizationally Unique Identifier (OUI).[4] The remainder of the address
* (three octets for MAC-48 and EUI-48 or five for EUI-64) are assigned by that organization in nearly
* any manner they please, subject to the constraint of uniqueness. A locally administered address is
* assigned to a device by a network administrator, overriding the burned-in address.
* Universally administered and locally administered addresses are distinguished by setting
* the second-least-significant bit of the first octet of the address. This bit is also referred to
* as the U/L bit, short for Universal/Local, which identifies how the address is administered.
* If the bit is 0, the address is universally administered. If it is 1, the address is locally administered.
* In the example address 06-00-00-00-00-00 the first octet is 06 (hex), the binary form of which is 00000110,
* where the second-least-significant bit is 1. Therefore, it is a locally administered address.[7] Consequently,
* this bit is 0 in all OUIs.
* In ESP32, universal MAC address is generated from the hardware MAC address in efuse.
* A `definition of local vs universal MAC address can be found on Wikipedia
* <https://en.wikipedia.org/wiki/MAC_address#Universal_vs._local>`.
* In ESP32, universal MAC address is generated from base MAC address in EFUSE or other external storage.
* Local MAC address is derived from the universal MAC address.
