-Subject: [PATCH 301/703] 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.
-
-See: https://github.com/raspberrypi/linux/issues/2447
