It was enabled again (d64ec841517a25f6d468bde9f67e5b4cffdc67c7) then
disabled (4521e1a94279ce610d3f9b7945c17d581f804242). It's closer
to 3.5 years :o)

Module parameters are frowned upon.

Lin, is there some interest in selectively [*] enabling (or disabling)
ASPM support in the r8169 driver or will it be unreliable ?

[*] Based on DMI information for instance.
