map: BR rule lookup update
Update to the MAP rule lookup (in IPv6) based on the rule's source
prefix instead of DMR
Type: improvement
Per RFC, the DMR is allowed to serve multiple MAP Basic Mapping Rules, but this
capability was prevented by the above logic.
Updates to the code include populating a new hash table based on the MAP rule
ip6 prefix and length, changing several functions to reference this new table,
and slight alterations to a few functions regarding pre-lookup bitmasking.
All changes are commented with [dgeist] and are in need of peer review,
especially the bitmask alterations.
An attempt was made at generating an additonal MAP rule in the test_map_br test
harness, but the coding appears very much oriented towards testing just one
rule. I would appreciate suggestions on how to test multi-rule cases.
