Всем привет!
Возник у меня вопрос, как определить по чипу что он умеет?
Вот тыкаю в OpenWRT и он там в настройках кажет возможные ширины каналов в зависимости от конкретной модели. При этом как я понял он это определяет «динамически».
Я пробовал много смотреть в вывод

Сам OpenWRT далее в rpc оперирует терминами VHT80 и VHT160, но от куда их берёт не понятно мне.
А чего это я ... Вот мне любопытно что может карточка AR9380 от TP-LINK TL-WDN4800, может хотя бы по личному знанию кто ответит...
