Hi,
I accidentally had MTU size mismatch (9000 vs. 1500) in my network, and I noticed I could kill a system using stmmac & 1500 MTU simply by pinging it with "ping -s 2000 ...".
While testing a fix I encountered also some other issues that need fixing.
I have tested these only with enhanced descriptors, so the normal descriptor changes need a careful review.
