Any suggestions ?

I forgot to add. The onboard NIC is a Broadcom card.

$ lspci | grep -i net
02:02.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL-8100/8101L/8139 PCI Fast Ethernet Adapter (rev 10) 02:09.0 Ethernet controller: Broadcom Inc. and subsidiaries BCM4401-B0 100Base-TX (rev 02)

This card gets randomly renamed to either eth0 or eth1 after every reboot.

This is weird.

Example 11.4

"Kernel always uses the ethX naming convention at boot when it enumerates network devices. Due to parallelization, the order of the kernel interface enumeration is expected to vary across reboots."
