I now have a gigabit PHY chip, out two pairs of TXD, two pairs of RXD, whether each with a pair of TXD + RXD correlates to do so

CodePudding user response:

Can't
Many thousands of trillion network physical layer can be adaptive support 10 m/100 m/1000 m, is a link, not two separate physical transceiver, can't open it,
In addition, if you need two independent front-end ports, also must have a MAC support, or you can use routing extensions chip, can be understood as a point added a second router
