Function esp_idf_hal::sys::esp_derive_local_mac

pub unsafe extern "C" fn esp_derive_local_mac(
    local_mac: *mut u8,
    universal_mac: *const u8,
) -> i32

@brief Derive local MAC address from universal MAC address.

This function copies a universal MAC address and then sets the “locally administered” bit (bit 0x2) in the first octet, creating a locally administered MAC address.

If the universal MAC address argument is already a locally administered MAC address, then the first octet is XORed with 0x4 in order to create a different locally administered MAC address.

@param local_mac base MAC address, length: 6 bytes. length: 6 bytes for MAC-48 @param universal_mac Source universal MAC address, length: 6 bytes.

@return ESP_OK on success
