Just checked history. It has been that way since beginning of time.
Initial vxlan implementation (year 2012) allowed migration of any
entry via learn. A 2013 commit 26a41ae60438 ("vxlan: only migrate
dynamic FDB entries") tried to fix it, but it added a check for static
entries only (NUD_NOARP) and missed permanent entries (NUD_PERMANENT).

I think we can add:
Fixes: 26a41ae60438 ("vxlan: only migrate dynamic FDB entries")

I can re-spin with this Fixes tag.
