I have already enabled both kernel-pfkey and kernel-netlink plugins. Both the plugins are loaded.
This was suggested by Andreas for my earlier query about pfkey plugin usage for IKEv1.
Since 4.5.3 is causing kernel-panic in my environment for unknown reasons, i want to resolve
the redundant child SA issue on 4.3.6. Please suggest me in resolving this issue.

You actually need both plugins on Linux, even if using kernel-pfkey to
install IPsec SAs and policies. The reason for this is that the
kernel-netlink plugin also implements the kernel_net_t interface which
is used for address and route lookups etc. You can enable both plugins,
the kernel-pfkey plugin is then loaded first by default (otherwise make
sure it is loaded first), which means that its kernel_ipsec_t
implementation is used while the kernel-netlink plugin can still provide
the required kernel_net_t implementation.
