5 * This is for the network variant 1 which has one ethernet port. It is
6 * different than the base variant, which also has one port, but here the
7 * port is connected via RGMII. This port is not TSN aware.
8 * None of the four SerDes lanes are used by the module, instead they are
9 * all led out to the carrier for customer use.
