TSE MAC and Marvell 88E1111

I'm having trouble to bring up the TSE MAC to Ethernet interface on the Stratix II GX PCIe board. I was able to instantiate a triple speed Ethernet MAC and build logic around it. The loopback at the ...

Hello to everybody i have another problem:

i took the example of sending of packet from tse driver, i also formed the descriptor for sgdma_tx, and try to send packet to PC.

Wireshark shows that packet with right number of bytes, but the packet is corrupted, besides all bytes of data are zero.

but i didn't configure the PHY.

I make lan adapter in PC to work in duplex 100 mbit and after hard reset PHY connects to it and by auto-negotiation works in duplex and 100 mbit - these parameters meet a demand of my fpga project.

then I form the packet as an example I took tse_mac_raw_send

Arу there any ideas why it doesn't work?

or where can i have a look for the control and status registers of PHY?

I use marvell 88e1111 and there is no datasheet for it.

can i take another datasheet to PHY with gigabit mode and look for the addresses of registers?

are there any standatrs for it?

thank for your help.
