Is the anybody can suggest me a solution how to get second ethernet port in TNETD7300 (D-Link 300T)?
It seems to be one of following ways:
1. find locations of second MAC pins.
2. connect external MAC via second Flexible Serial Interface - how to find locations of it's pins?
3. connect external MAC via VLYNQ™ High-Speed Point-to-Point Serial
    Interface - how to find locations of it's pins, and what chip to use as MAC via VLYNQ?
4. Use IEEE Std. 802.1q support and connect an external 802.1q Switch to an existing Ethernet port...

Thank you for your help

PS Sorry for my english
