Intel has verified that there is no peer-to-peer between functions for the below selection of 82580, 82576, 82575, I350, and 82571 multi-port devices. This adds the necessary quirks to consider the functions isolated from each other. 82571 quad-port devices are omitted due to likely lack of ACS/isolation in the onboard switch, rendering quirks for the downstream endpoints useless.
