Yes, the target side does not matter. In fact I have also reported a
similar bug in vblade that got fixed in vblade-15.

Thinking a bit more I think the issue in this case arises when the
_target_ is sending on a tagged VLAN interface. aoecfg & aoeping expects
packets to be padded to have at least 60 bytes of length. But if the
VLAN tag is added before the padding happens, then on receipt the
removal of the VLAN tag means the remaining padded data is just 56 bytes
long.
