Baixou a versão 8 e instalou regularmente seguindo o README do driver:

Depois disso, correu rmmod e1000 e modprobe e1000 . Todos os arquivos de configuração ainda estão onde estavam. lsmod mostra que o módulo está carregado.
Modinfo mostra nova versão do driver.

Mas apenas as interfaces eth0 e eth1 estão agora disponíveis. Então eth2, eth3, eth4 e eth5 se foram agora.

A reinicialização não ajudou. O dmesg não mostra nenhuma tentativa de trazer outras interfaces:

Eu passei muito tempo tentando fazer isso funcionar. Não me lembro de todas as coisas que tentei. Eu ficaria muito satisfeito com sugestões, dicas ou informações sobre como o sistema traz interfaces de rede e qual poderia ser a razão de não fazer isso agora.
