SubjectRe: [PATCH 2/2] alx: add disable_wol paramenter
The problem is I don't have a machine with that wakeup issue, and I
need WoL feature.
Instead of spreading "alx with WoL" dkms package everywhere, I would
like to see it's supported in the driver and is disabled by default.

Moreover, the wakeup issue may come from old Atheros chips, or result
from buggy BIOS.
With the WoL has been removed from the driver, no one will report
issue about that, and we don't have any chance to find a fix for it.

Adding this feature back is not covering a paper on the issue, it
makes people have a chance to examine this feature.
