Merge branch 'bcm_sf2-Add-support-for-IPv6-CFP-rules'
Florian Fainelli says: ==================== 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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
