It makes me wonder if it is expected behavior for
ibnl_rcv_reply_skb() to handle !NLM_F_REQUEST messages and do we
really need it? What are the scenarios?  In my use case, which is
for sure different from yours, I'm always setting NLM_F_REQUEST
while communicating with kernel.

If I recall the user space SA code issues REQUESTS from the kernel to
userspace, so userspace returns with the response format. This is
abnormal for netlink hence the special function.
