Andrey,
please file a bug to RedHat about this (and add me to CC there
<[email protected]>).
Meanwhile i'm applying those patches in order to unblock debug kernel runs.

I think we can just notify Red Hat about this problem

From: Jacob Keller <[email protected]>
This function previously had the same check as used by the
ixgbe_pcie_from_parent. As the hardcode is due to the device having an internal
switch, this function should simply use the call from ixgbe_pcie_from_parent.
This reduces code complexity and makes it less likely a developer will forget
to update the list in the future.
