cipUrpfIfSuppressedDrops

The number of IP packets of version cipUrpfIfIpVersion
failing the URPF check but given a reprieve and not 
dropped by the managed device. Depending on the 
device configuration and capabilities, the following 
cases may cause incrementing of the counter: 
- if the managed device is configured to allow self-pings 
  and the managed device pings itself.
- if the managed device is configured for loose URPF (if any
  interface has a route to the source), and the strict
  case fails while the loose case passes.
- DHCP Request packets (src 0.0.0.0 dst 255.255.255.255) 
  will pass after initially being marked for drop.
- RIP routing on unnumbered interfaces will pass after 
  initially being marked for drop.
- multicast packets will pass after initially being marked 
  for drop
- ACL's can be applied to permit packets after initially 
  being marked for drop.
              
Discontinuities in the value of this variable can occur 
at re-initialization of the management system, and at 
other times as indicated by the values of 
cipUrpfIfDiscontinuityTime.
