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.
