Some Lenovo Docking station misbehaves when laptop pluged is put to suspend,
creating a ethernet packet storm on the dock ethernet port which can bring down
some ethernet switches.

This is a know bug, fixed in upstream kernel (see
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/usb/r8152.c?h=v6.0-rc4&id=cb82a54904a99df9e8f9e9d282046055dae5a730
)
but the fix needs to be applied per Docking station and my docking station is
not listed there.

Would it be possible to add it to the list (and enable also the MAC spoofing
feature see
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/net/usb/r8152.c?h=v6.0-rc4&id=1bd3a383075c64d638e65d263c9267b08ee7733c
) ?

I'm not sure which usbid are the one used to detect the docking station.

Possible values are :
Bus 003 Device 038: ID 17ef:30b9 Lenovo USB2.0 Hub             
Bus 003 Device 036: ID 17ef:30b7 Lenovo USB2.0 Hub             
Bus 003 Device 035: ID 17ef:30b5 Lenovo 40B0
Bus 003 Device 042: ID 17ef:30b4 Lenovo ThinkPad Thunderbolt 4 Dock MCU
Contoller
Bus 003 Device 034: ID 17ef:30ba Lenovo V1003

Docking station is a ThinkPad Thunderbolt 4 WorkStation Dock :

I'll be happy to test any kernel with the proper id applied.
