Subject: [PATCH 0133/1085] lan78xx: Debounce link events to minimize poll
|
|
storm
|
|
|
|
The bInterval is set to 4 (i.e. 8 microframes => 1ms) and the only bit
|
|
that the driver pays attention to is "link was reset". If there's a
|
|
flapping status bit in that endpoint data, (such as if PHY negotiation
|
|
needs a few tries to get a stable link) then polling at a slower rate
|
|
would act as a de-bounce.
|
|
|
|
