OK. Então os Googles vieram através de mim. Veja como corrigir o problema.
Acontece que, para usar o sistema de arquivos de depuração, ele precisa ser montado primeiro. Estamos usando um sistema operacional memfs para executar comandos nas máquinas que estamos ajustando e, por padrão, não montamos debugfs. Então este script me deu a resposta I necessário.
... e os seguintes passos para o meu caso de uso funcionaram:
root@host (~)# mount -t debugfs none /sys/kernel/debug
root@host (~)# echo lldp stop > /sys/kernel/debug/i40e/0000:01:00.2/command
cedendo:
root@host (~)# lldptool -i eth2 stat
