net: napi: remove useless stack trace
Whenever a buggy NAPI driver returns more than its budget, we emit a stack trace that is of no use, since it does not tell which driver is buggy. Instead, emit a message giving the function name, and a descriptive message. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
