/*

* DP83820/DP83821 with H/W VLAN stripping does not accept short VLAN
|
|
* tagged packets such as ARP, short icmp echo request, etc. It seems
|
|
* that MAC checks frame length for VLAN tagged packets after stripping
|
|
* the VLAN tag. For short VLAN tagged packets it would would be 56
|
|
* (64 - CRC - VLAN info) bytes in length after stripping VLAN tag.
|
|
* If the VLAN tag stripped frames are less than 60 bytes in length
|
|
* the hardware think it received runt packets!
