Eu tenho 2 máquinas (PC e laptop) e um switch gigabit, ambos NIC são gigabit, os cabos são Cat-5E, o PC é habilitado para gigabit:

$ ethtool enp1s0

Eu tentei:

$ sudo mii-tool 1000baseTx-HD enp3s0
SIOCGMIIPHY on '1000baseTx-HD' failed: No such device
enp3s0: negotiated 100baseTx-FD flow-control, link ok

qual é o problema possível?
