Creating Ethernet Frames

I've got an Aria V starter board with Marvell PHY. I'm trying to get some data from the board to the PC over the ethernet. The QSYS system is all wired up and I can do DMAs from an internal memory ...

thanks guys, I ended up finding the setting in the TSE guide like you posted. Makes sense. I am looking at my ethernet frames on a logic analyzer and all looks well but still not packets making it to wireshark. I am not doing any kind of initialization on the Marvel chip other than a reset. It appears to auto negotiate and come up with the correct speed setting and TX light blinks when I throw a frame at it.

Is there any required initialization for the Marvel PHY or should it just work out of reset?

thanks!
