2.1 Fast Link-Drop (FLD) Strap Configuration

The DP83826x and DP83826Ax supports an enhanced link-drop mechanism, also called fast link-drop (FLD), which shortens the observation window for determining a link. There are multiple ways of determining the link status, which can be enabled or disabled based on user preference.
