  Modified files:
    sys/net              if_vlan.c 
  Log:
  In vlan_input(), if the network interface does not perform h/w based
  vlan tag processing, the code will use bcopy() to remove the vlan
  tag field but the code copies 2 bytes too many, which essentially
  overwrites the protocol type field.
  
  Also, a tag value of -1 is generated for unrecognized interface type,
  which would cause an invalid memory access in the vlans[] array.
  
  In addition, removed a line of dead code and its associated comments.
