====================
net: dsa: bcm_sf2: Add support for IPv6 CFP rules

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.
