VLAN и прием нетегированных пакетов

Зачем? Проверить маршрутизатор? Он рабочий. Именно управляемым коммутатором его работоспособность и проверялась. Задача не уйти от vlan'ов в linux, а добиться их полной и безоговорочной работоспособности. Причем необходимо обрабатывать как минимум 3 vlan'а.
По поводу проверки - у меня на каждом из двух интерфейсов поднято по четыре vlan, всё работает.

Да, ещё вопрос появился - а на рутере случайно нет правил принудительной маршрутизации? Пакет снабжается тэгом на выходном интерфейсе, если рутеру сказано всё валить в нормальный, они и будут не тэгированными.
Нет, на маршрутизаторе нет никакой принудительной маршрутизации. Весь конфиг маршрутизатора я привел в первом сообщении. Никакой там маршрутизации и не нужно, всё сети считаются “directly connected”, соответственно ничего сверхъестественного он выдумывать не должен.
Будет интересно посмотреть на вывод Вашего sysctl. В качестве сравнения привожу свой:

Думаю истину можно именно в нем и найти, только ума не приложу во что именно нужно глядеть.
Не силен в vlan за неимением оборудования хорошего, но когда я прочитал , почемуто первое впечатление тоже было в сторону маршрутизации. Но в силу того , что не начем попробовать, решил не писать, чтобы не путать людей. Раз уж тупик, чирканул.
Лозунг у них был такой: "Познание бесконечности требует бесконечного времени". С этим я не спорил, но они делали из этого неожиданный вывод: "А потому работай не работай — все едино". И в интересах неувеличения энтропии Вселенной они не работали. (с)
У меня вывод раза в три длиннее, главное отличие - в начале и конце нет предупреждений о “permission denied”, имеет смысл покопать в ту сторону.
Проблема с приемом нетегированного трафика решилась с очередным обновлением ядра до 3.3.6-1-ARCH. Была пофиксина именно эта проблема, если конечно я правильно понял написанное sky2: fix receive length error in mixed non-VLAN/VLAN traffic
Но теперь, при выше описанных настройка, на родительском интерфейсе при попытке пропинговать подинтерфейс маршрутизатор на приеме tcpdump'ом ничего не видно, хотя счётчики на принимаемых пакетах в ifconfig увеличиваются.

Не понятно, это что то всё еще не доконфигуренное мною или всё еще недофиксенные баги драйвера.
Чудеса в сетевой части бывают… У меня, как я уже писал, два сетевых интерфейса:
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06)
06:01.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8139/8139C/8139C+ (rev 10)
Так вот при загрузке компа первый из инициируемых интерфейсов не поднимается, не зависимо какой поставить первым. В результате при загрузке поднимается только один, второй поднимаю руками.
Не поднимается в смысле ip link eth0 set up или в смысле загрузки модуля?
В rc.conf конструкция
interface=eth1
address=192.168.21.188
netmask=255.255.255.0
broadcast=192.168.21.255
#
interface=eth0
address=192.168.130.106
netmask=255.255.255.0
broadcast=192.168.130.255
gateway=192.168.130.100
netw="192.168.130.0/24 dev eth0"
gatew="default via 192.168.130.100"
ROUTES=(netw gatew)
eth0 и eth1 “прибиты” к МАСам. Так вот после загрузки eth1 не инициализирован, в логе загрузки ничего не записано. Если вперёд поставить eth0 - будет не инициализирован он.
Ы…
Такая конструкция никогда не работала и работать не может, потому что файл rc.conf это просто bash-скрипт, все параметры это ПРОСТО ПЕРЕМЕННЫЕ. Как вы уже правильно догадываетесь, наверное, если вы присвоите переменной последовательно два значения – в ней благополучно сохранится последнее.

Настройка нескольких сетевых карт в rc.conf БЫЛА сделана через массивы, и её уже упразднили, оставили только упрощённую версию для одной.
Читайте вики по rc.conf, netcfg или пишите свой собственный скрипт поднятия сети, вроде такого:
