Reviewing two IPFW/netgraph/natd patches (RFC 6598/Carrier Grade NAT)

[Neel Chauhan]

Hi freebsd-hackers@, freebsd-net@,

These two patches that will be described are a continuation of r357092.

r357092 added support for RFC 6598/Carrier Grade NAT (subnet: 
100.64.0.0/10) in libalias and IPFW in-kernel NAT.

These two patches add support for RFC 6598 to natd and ng_nat 
respectively:

  * natd CGN patch: https://reviews.freebsd.org/D23356
  * ng_nat CGN patch: https://reviews.freebsd.org/D23461

Currently, CGN support is missing from natd and ng_nat.

Could someone please review and/or commit these patches?

Best,

Neel Chauhan
