Subject: [PATCH] net: phy: lan87xx: Allow more time for link detect
|
|
|
|
With EDPWRDOWN set in idle, it must be cleared before checking for
|
|
ENERGYON going high, indicating that a link is being established.
|
|
The existing code allows 640ms for ENERGYON to go high, but on
|
|
Raspberry Pis that appears not to be enough, causing link detection
|
|
to fail.
|
|
|
|
Increase the polling timeout to 1500ms - with a polling interval of
|
|
10ms it shouldn't cause unnecessary delays.
|
|
|
|
