Could someone help investigate whether the new checks can interfere with EVPN/FRR-installed nexthop FDB entries, or whether this exposes another issue in the VXLAN FDB handling?
I believe we need to relax the checks to allow "extern_learn" entries.
They are not subject to ageing (vxlan_cleanup() skips them), so they
cannot trigger the bug that commit 98fc57d16744 ("vxlan: reject dynamic
fdb entries that reference a nexthop id") fixed. Let me do some testing.
