Hello!
With FreeBSD 14.0-RELEASE I have this (quite old) network interface,
which is embedded in the motherboard:

nfe0: Ethernet address: ...
It performed normally for several days and across several reboots. Then,
without applying any modification to the configuration, the system was
physically powered down and booted again: the network card did no more
work. After another reboot, nothing changed.
The two LEDs in the Ethernet socket are active: the orange one is fixed,
the green one blinks every now and then (not so often). After physically
disconnecting and reconnecting the Ethernet cable, nothing changed.
The host can not ping the LAN and can not receive ping. All the network
settings (which worked till some minutes before) are ok, including
`ifconfig', where it is `UP', 1000BaseT; routes and /etc/resolv.conf
are OK.
The only relevant information is maybe at the end of the dmesg, where
after some minutes this sequence has been printed several times:
nfe0: watchdog timeout
nfe0: link state changed to DOWN
nfe0: link state changed to UP
but even when `link state changed to UP' the interface does not work.
Is there anything that can be done from the OS, or is it a hardware issue?
Bye!
Rocky
