Rafael, let me know if you want me to adjust the commit message and resubmit
or if you would just handle this task.

Although Dell arranged a lot of testing with partners I don't feel d916b1be is a stable
candidate. Rafael found a corner case with regards to ASPM configuration last minute
in 5.3rcX, I found a another corner case related to order of events and timing around
PC10 entry that's getting fixed in 5.4.
