Sync with userspace instead of kernel

Is there any way in BIRD to sync the routing table directly with userspace instead of the OS kernel? We are managing forwarding tables in a userspace (DPDK) application instead of the kernel and want to avoid duplicating the table in both. I see a possible way of doing this with a patch to set `nl_pid` in nl_send() inside of sysdep/linux/netlink.c. But has anyone used BIRD for this use case before?
