fdb_add() ignored any errors returned by the hardware (for example,

I'm not sure this deserves a Fixes tag. How many entries does the
table take before it is full? Typical home networks have what, 10, 20
devices maximum. A small business network may have a couple of
hundred?
What happens if it is full, and you don't return ENOSPC?
