A little hint for Realtek NICs users experiencing stability and availability issues

I changed my mainboard…

dmidecode |grep Product
        Product Name: DG41RQ

A with a bit better watt-to-computational ratio CPU

cat /proc/cpuinfo  |grep name
model name      : Pentium(R) Dual-Core  CPU      E5400  @ 2.70GHz

But with “kinda the same” NIC

lspci |grep Ethernet
03:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 03)

Almost 200hrs of flawless work. Rebooted today for a newer kernel
