To prevent ambiguity between configurations, we had to change the naming format of configuration
keys. Before, we used {prefix}_{key}, which meant that esp-hal and esp-hal-* configuration keys
were impossible to tell apart. To fix this issue, we are changing the separator from one underscore
character to _CONFIG_. This also means that users will have to change their config.toml
configurations to match the new format.

-ESP_IEEE802154_RX_QUEUE_SIZE = "50"
