yep 😉  
while LAN9730 not get the IP-address by DHCP, in the modem network interface eth0 does not appear

here is another question: how can I set DHCP server mode on LAN9730 by HSIC?

A few basic questions:  
a. Have you made a separate board for this?  
b. If so, what is the trace length for HSIC
