Ethernet MAC/PHY (LAN91C111) with Stratix II

Don't trust Altera's documentation for the pins assignments, it seems to be wrong (it's not the first time, unfortunately).

Have a look at the schematics to find the correct pins instead. From what I'm seeing (I hope I found the correct schematic on the net), those are the correct assignments:

[list][*]ENET_DATACS_N: AB24 instead of T20

[*]ENET_IOCHRDY: AB25 instead of V26

[*]ENET_LDEV_N: AA24 instead of T26

[*]ENET_SRDY_N: AA23 instead of T25

[*]ENET_W_R_N: AE27 instead of T21[/list]

You should check all the other pins too, you never know what other mistakes they made in their documentation...
