Have a look at etharp.c at the places where both dropped and err are increased
an you see where it can come from! Most certainly, there has been something
from with received ARP packets (etharp.c), but these counters could also be
increased in your netif driver source file.
In etharp.c, there are multiple places where both counters are increased, so
you might want to either debug this or add additional counters to see which one
fired.
