Well, I meant that loading modules can be an issue but that's not the 
way to verify that.

You need to have all modules built-in so that it proves that no module 
will try to be loaded.

Anyway, this is probably not the cause as you wouldn't even be able to 
compile kernel if you need a symbol from a module with stmmac built-in. 
Kconfig would complain about that.

The other cause could be data corruption in the RX path. Are you able to 
send me packet dump by running wireshark either in the transmitter side 
(i.e. NFS server), or using some kind of switch ?
