[Oberon] MTU and Ethernet NIC drivers.

[J ö rg Straube]

Hi Peter

I didn't look at the Net3Com source code!

But a standard Ethernet MTU (not being a Jumbo Frame)
is defined as 1500 bytes.

So, with the 14 bytes Ethernet header this makes 1514.

- I guess the 4 byte CRC is NOT included in that "MaxPkt".
  If CRC is included, "MaxPkt" should be 1518.

- I guess the 4 byte VLAN is not included either. Else
  the "MaxPkt" should be 1522
