Select the storage location of the base MAC addresses.

1. eFuse BLK0: The "Default (Espressif factory)" selection. The
|

default base MAC address is written to words 1 and 2 of eFuse block
|
||||
0 when the chip was manufactured. Call esp_efuse_mac_get_default()
|
||||
read retrieve the "eFuse BLK0" MAC address.
|
||||
2. eFuse BLK3: A custom base MAC address is burned by the user into
|
||||
eFuse word 0 of block 3. Call esp_efuse_mac_get_custom() to read
|
||||
the "eFuse BLK3" MAC address.
|
||||
3. Other External Storage: Selecting this option will cause the
|
||||
example to call external_storage_mac_get() which is defined in this
|
||||
example to simply return a MAC address preset in software. Users
|

should modify this function to access their desired storage mediums
