STM32 lwIP PPPoS, STM32 lwIP PPPoS Опции

[eisufu]

Не знаю, существуют ли русскоязычные гуру в PPP, но рискну.
На STM32F407 крутится FreeRTOS с lwIP. Пытаюсь установить PPP-соединение, но оно не устанавливается до конца. Собрал с выводом диагностической информации (лог - ниже), но интерпретировать не могу. Видел в интернете, что у людей возникают схожие проблемы, но решений и у них нет. Помогите пожалуйста найти решение проблемы.
Пакеты фрагментируются, та как приходится перенаправлять траффик с USB-модема, подключённого к компьютеру, на устройство и обратно. Скрипт в режиме поллинга с периодом 0.1 секунды читает и пишет из виртуального COM-порта USB-модема в COM-порт, к которому подключено устройство, и наоборот. Думаю пакеты из байтов должны нормально собираться. sio_read не бесконечно блокирующая, стоит таймаут 1.5 секунды. Иначе вообще ничего не получается.

мда. ступенька на каждом шагу.
уважаемый kan35, не могли бы вы намекнуть на причины следующей проблемы: после переговоров PPP (после получения IP-адресов в IPCP переговорах) lwIP уже создан ppp-интерфейс, потому я создаю netconn TCP соединение (например на порт 80 одного из IP google.com), но IP соединение не создаётся, так как нет ответа от сайта. вот лог:
