This patch set implements:
- A compare function can be passed in the lookup. This allows for
comparison to include "wildcard fields"
- Order insertion within a bucket, so that entries with more specific
information can be matched first.
- Scored lookups. This is like the socket lookups. It allows
different levels of matching, and returning one of N possible
best matches with a uniform distribution based on flow hash.
Testing: Tested this in conjunction with ILA development. Will be
posting ILA patches shortly.
