We try to avoid acronyms and abbreviations unless they are very widely
established. Hence I am not convinced "Neigh" is something we should
use.

Given that "fdb" and "entry" are commonly used I think [FDBEntry]
would be fine.

If I get this right "fdb" only makes sense in a bridge context,
correct? Maybe [BridgeFDBEntry] instead?

Hmm, networkd takes ownership of the network interfaces it is
configured to manage, hence I am wondering whether the flushing of the
FDB should not be the implied logic when it takes possession of an
interface? Is there a good usecase why one would *not* want this? I
mean, if networkd would simply flush the fdb of bridge devices
unconditionally when it initializes that interface, would that be a
problem?
