Ok here are the commands I did and the results 

modprobe r8169

lsmod | grep r8169
r8169                 114688  0
mdio_devres            12288  1 r8169
libphy                245760  3 r8169,mdio_devres,realtek

echo -n "10ec 8126 ffff ffff 0 0 0" > /sys/bus/pci/drivers/r8169/new_id

echo -n "0000:05:00.0" > /sys/bus/pci/drivers/r8169/bind
-bash: echo: write error: No such device

ls -al  '/sys/bus/pci/devices/0000:05:00.0'
lrwxrwxrwx 1 root root 0 Dec 22 23:23 /sys/bus/pci/devices/0000:05:00.0 ->
../../../devices/pci0000:00/0000:00:1c.3/0000:05:00.0

cat '/sys/bus/pci/devices/0000:05:00.0/device'
0x8126


I also ran journalctl -b -xef while doing the 2 echo commands and no messages
were shown.

So it seems to see the 0000:05:00.0 device as the 8126 so I don't understand
why your second echo says "No such device"
