This is still handled correctly.  The new code only checks for L3 broadcast
addresses on L2 broadcast packets, but we still check the L3 address before
treating it as a broadcast. The problem is that I assumed that all paths
into the IP stack would set M_BCAST, but as Bruce has pointed out there are
cases like PPP which do not.
