Thanks for the review John.  Yes, we are also looking for getting u32
to start from L2 header in order to allow matching encapsulation
protocols in front of IP header.

In addition, our hardware also keeps track of per-filter statistics
such as number of times the filter has been hit and number of bytes
that hit the filter. Hence, we are also looking for exposing these
per-filter stats to u32.
