Suspend / resume utilizing WOL (wake-on-LAN) stopped working when Tumbleweed
went from 6.1.x kernels to 6.2.x kernels. It worked great until then for a long
time. Ethernet interface still tells that wake-on-LAN is enabled like before
(setting is defined in /etc/sysconfig/network/ifcfg-eth0). When machine
suspends, ethernet adapter shuts down completely. Machine wakes up from suspend
by pressing power button.

$ ethtool eth0 | grep -i wake
        Supports Wake-on: pumbg
        Wake-on: g

$ lspci  | grep -i ethernet
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411
PCI Express Gigabit Ethernet Controller (rev 09)

I can see from system journal logs that nightly backups resumed that machine
neatly with 6.1.12 kernel, but no longer with 6.2.0 and later kernels up and
including version 6.2.6. There is nothing unusual logged into system journal as
fas as I can tell.

I haven���������t changed any procedures myself. Tumbleweed updates have done all
changes. I have also few other machines with different ethernet cards, where
WOL still works with 6.2.x kernels.
