NIOS: MDIO: Platform Designer generates altera_eth_mdio.v that doesn't work

Ok, found it.

The TLK10232 we use in this project requires a longer MDIO preamble than the nios generates. So my colleague manually changed the file. And replaced it after generating new NIOS files. I didn't expect that...

We use Quartus Version18.1. Maybe in a newer Version this problem is fixed. If not it's maybe a good idea to make the preamble length configurable.

Have a nice day.

Best regards,
