esp_read_mac() function

Read base MAC address and set MAC address of the interface. This function first get base MAC address using esp_base_mac_addr_get(). Then calculates the MAC address of the specific interface requested, refer to ESP-IDF Programming Guide for the algorithm. The MAC address set by the esp_iface_mac_addr_set() function will not depend on the base MAC address.
