This extends espintcp to support IPv6, building on the existing code and the new UDPv6 encapsulation support. Most of the code is either reused directly (stream parser, ULP) or very similar to the IPv4 variant (net/ipv6/esp6.c changes). The separation of config options for IPv4 and IPv6 espintcp requires a bit of Kconfig gymnastics to enable the core code.
