10GBE IP is a HighSpeed mac that supports 1G, 2.5G, 5G, and 10G speeds and has two PCS. It has USX PCS for higher speed and SGMII PCS for lower speed transmission. Auto-neg is disabled for this IP in versal2 device, hence "fixed-link" at the specified speed is used. It is an expansion of the fixed-line speed at 10G currently being implemented. These modifications are tested using a HW board configuration without a PHY with QSFP. The IP contains MDIO lines, and the goal is to use auto-neg in the PHY and set the agreed-upon speed in the MAC. These adjustments will be made in the following phase after the extra hardware is available.
