Analyze and fix the following issue in the Linux kernel code: net: dsa: mv88e6xxx: propperly shutdown PPU re-enable timer on destroy
Problem Details: The mv88e6xxx has an internal PPU that polls PHY state. If we want to access the internal PHYs, we need to disable the PPU first. Because that is a slow operation, a 10ms timer is used to re-enable it, canceled with every access, so bulk operations effectively only disable it once and re-enable it some...
