TX Hang Unit
Hello, guys... 
I have a question.
My routing server has TX Hang. Every couple of days. It makes me CRAZY!
It doesn't solve. I also tried changing the NIC. This only happens in 1 port enp1s0f1. The other one, enp1s0f0, is fine. So it seems it's the drivers with my Debian 12.
DCTL.ENABLE for one or more queues not
cleared within the polling period

With no LUCK. I also tried changing transceivers. (It's a dual NIC), the affected port has a FIBER cable connected. The other one is a standard ethernet cable. So, for sure, it looks like driver issues.
I think the NIC is Intel® 82599ES, but
lspci -v says it's also a subsystem of X520.
I'm using the last Debian 12/Kernel.
I can't upgrade firmware due to kernel incompatibility.
Should I try another OS? Maybe Rocky Linux? Or use VMWare with a VM?
VMWare seems to have perfect support for these drivers.

Ty everyone. I will wait for your opinions.

Have you ruled out an intentional outage so law enforcement can generate SSL certificates for your hosts?
Looks like a popular issue: https://forum.proxmox.com/threads/ixgbe-driver-hang-up-detected-tx-unit-hang-tx-queue.120328/
UPD: there is some report that disabling LRO helps (I don't see lro amongs yours disabled offloads)
Thanks. I see that Intel sucks! lol.
I already tried with LRO, and almost all NIC stuff is OFF...
What is weird is it only happens on the Fiber port. The Ethernet port is always OK.
I will maybe get an X720 and replace it with it.
Try a Mellanox, dirt cheap on ebay
