Hello,

Linux-6.5.8. X710 Network card, attached via 1meter DAC cable to an
Ubiquiti Aggregation switch (10Gbe).
Networking is fine, throughput as expected,  but the X710 stops
forwarding packets after ~20 hours.
I have to "ifconfig enp1s0f1 down ; sleep 1; ifconfig enp1s0f1 up" to
get it working again;
pulling and reinserting the DAC cable does not help.

Interface is part of a linux ethernet bridge device (br0), the X710 is
used purely as a dumb fast
ethernet device, no advances features enabled.

Any ideas what could be wrong?

Thanks!
     Manuel
