Can you elaborate what L23 is or should the commit message be reworded
as "Disable a (yet undocumented) power saving feature that randomly
causes RTL8411, RTL8111G, RTL8402, RTL8105, and RTL8106 devices to be
lost on some systems." ?

The L2/L3 are the link status which are defined in the specification of the PCI
Express Base Specification for the link state power manager. I don't know them
much, so I don't sure if I could explain them clearly. 

Best Regards,
Hayes
