Jacek Caban (@jacek) commented about dlls/netprofm/list.c:
+ { + network->ipv6 = TRUE; + connection->ipv6 = TRUE; + network->ipv4 = FALSE; + connection->ipv4 = FALSE; + if (aa->u1.Flags & IP_ADAPTER_IPV4_ENABLED) + { + network->ipv4 = TRUE; + connection->ipv4 = TRUE; + } + } + else + { + network->ipv4 = TRUE; + connection->ipv4 = TRUE; + } IP_ADAPTER_IPV4_ENABLED checks look suspicious here, you check it only if IP_ADAPTER_IPV6_ENABLED is set but assume it unconditionally otherwise. Is it a workaround for the fact that those flags are not implemented in Wine?
