regarding ring buffer

hi,
  I have modified skbuff to add a custom phy header instead of the usual
packet by
slapping the custom header at the start of packets.
Instead of pcap, i am reading from raw socket now, but I don't have any
mechanism to
know if any wireless frames were dropped by the ring buffer.. the
statistics pcap gives ...
Can anyone suggest how to get this information while i am writing code in
userland.
