Hi all, This patch series adds support for matching IPv6 addresses to the existing CFP support code. Because IPv6 addresses are four times bigger than IPv4, we can fit them anymore in a single slice, so we need to chain two in order to have a complete match. This makes us require a second bitmap tracking unique rules so we don't over populate the TCAM.
Finally, because the code had to be re-organized, it became a lot easier to support arbitrary prefix/mask lengths, so the last two patches do just that.
