If you have an invalid MAC CRC (ESP_ERR_INVALID_CRC) problem
and you still want to use this chip, you can enable this option to bypass such an error.
This applies to both MAC_FACTORY and CUSTOM_MAC efuses.
config ESP_MAC_USE_CUSTOM_MAC_AS_BASE_MAC
bool "Enable using custom mac as base mac"
default n
help
When this configuration is enabled, the user can invoke `esp_read_mac` to obtain the desired type of
MAC using a custom MAC as the base MAC.
