For both settings, REGULATORY_STRICT_REG will be set, telling stack that devices original regulatory is the superset of any further settings. For the chipset with the country setting being a specific country, Realtek does not apply any new regulatory setting notifiers to the card. For the chipset with a worldwide regulatory setting, Realtek's custom worldwide regulatory setting will be provided via wiphy_apply_custom_regulatory(). And if a new regulatory notification is set by NL80211_REGDOM_SET_BY_COUNTRY_IE, the new setting will be applied to the card.
