E ai pessoal, estou quebrando a cabeça para subir uma interface de rede. Com o lspci ela aparece, esta la, com o ifconfig -a ela é exibida mas somente o ifconfig não mostra ela, ela é a placa de rede local, configurada com um ip fixo, o qual o servidor DHCP vai ser configurado sobre ela. O que me parece é que as duas estão usando o mesmo paramêntro de nomes eth0, conforme segue abaixo o erro, as placas ja foram configuradas
