Abstract
A system for adjusting late collision slot time is provided in a network interface having a media access control (MAC) engine that performs collision detection. The MAC engine comprises a MAC transmit block that transmits frames via a media independent interface (MII) to an ektemal physical layer device (PHY) coupled to the MII, and a MAC receive block for receiving frames from the PHY. A MAC control register is configured for storing ablate collision time slot adjustment value used to adjust the late collision slot time. The late collision time slot adjustment value is programmed to compensate for variations in internal delays of PHYs that may be connected to the MII.
