  Log:
  Introduce a new sysctl variable:
  
  security.mac.biba.interfaces_equal
  
  If non-zero, all network interfaces be created with the label:
  
  biba/equal(equal-equal)
  
  This is useful where programs which initialize network interfaces
  do not have any labeling support. This includes dhclient and ppp. A
  long term solution is to add labeling support into dhclient(8)
  and ppp(8), and remove this variable.
  
  It should be noted that this behavior is different then setting the:
  
  security.mac.biba.trust_all_interfaces
  
  sysctl variable, as this will create interfaces with a biba/high label.
  Lower integrity processes are not able to write to the interface in this
  event. The security.mac.biba.interfaces_equal will override
  trust_all_interfaces.
  
  The security.mac.biba.interfaces_equal variable will be set to zero
  or disabled by default.
