After kernel update to 6.2.0-26 and newer. The my device experience network problem from time to time. In the end, I found the NIC card actually fall off from the pcie bus:
```
lspci -vnnk
03:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev ff) (prog-if ff)
DeviceName: GLAN
!!! Unknown header type 7f
Kernel modules: r8169
```
Only reboot can reinitiate the nic.
6.2.0-32-generic #32~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Fri Aug 18 10:40:13 UTC 2 x86_64 x86_64 x86_64 GNU/Linux
The NIC is this one https://linux-hardware.org/?id=pci:10ec-8168-1043-208f
