Subject: [PATCH] e1000e: bump up timeout to wait when ME un-configure ULP mode
|
|
|
|
ME takes 2+ seconds to un-configure ULP mode done after resume
|
|
from s2idle on some ThinkPad laptops.
|
|
Without enough wait, reset and re-init will fail with error.
|
|
|
|
Fixes: f15bb6dde738cc8fa0 ("e1000e: Add support for S0ix")
