[Click] Broadcast packets in ARPQuerier

[Dagang LI]

Dear all,

Seems that the ARPQuerier does not differentiate broadcast IP packets 
from unicast IP packets,
this way when it receives a broadcast packet it will send queries for 
that broadcast IP address
which will never be replied. Can we solve this by adding several entries 
in the _map[] table for
these special addresses before hand when the table is initiated? Such as 
mapping between
255.255.255.255 and FF:FF:FF:FF:FF:FF.

Kind regards,
