Subject: [PATCH 45/47] r8169: disable ALDPS per default for RTL8125
|
|
|
|
En-Wei reported that traffic breaks if cable is unplugged for more
|
|
than 3s and then re-plugged. This was supposed to be fixed by
|
|
621735f59064 ("r8169: fix rare issue with broken rx after link-down on
|
|
RTL8125"). But apparently this didn't fix the issue for everybody.
|
|
The 3s threshold rang a bell, as this is the delay after which ALDPS
|
|
kicks in. And indeed disabling ALDPS fixes the issue for this user.
|
|
Maybe this fixes the issue in general. In a follow-up step we could
|
|
remove the first fix attempt and see whether anybody complains.
