Приветствую. Подскажите пожалуйста, КУДА написать о найденной баге в команде iwlist. И вообще бага ли это ?
Вступление
iwlist - команда из пакета wireless-tools для получения развернутой инфы о точках доступа.
Суть баги
iwlist <devname> scanning - выводит список доступных точек доступа.
iwlist <devname> scanning essid <имя очки доступа> - выводит информацию о конкретной точке доступа
Но если выполнить сканирование, а затем попытаться вывести информацию о конкретной AP - ключ essid как будто игнорируется.

2) Но если выполнить вначале сканирование всех AP, а потом попытаться получить инфу о конкретной AP - ключи 'essid AP' как будто игнорируются и просто выполняется сканирование вафли:
