But about inter-connect of PHY and MAC.
I test similar configuration in DE2-115 board which inculde Marvell 88E1111 PHY layer.
(Samll TSE MAC that connect to PHY via MII interface)
every things works fine!
I ran simple socket server example on DE2-115 board and it was very interesting.
but i can't understant what is this problem that only appear in RX path not on TX path!
thanks for your attention
