This patch will add fix to allow DHCP broadcast packets, so that AP can forward DHCP broadcast offer to clients
cause:
In the bridge source code, there is a mechanism to drop all the broadcast packets if the proxy arp is enabled, because of this dhcp clients which set broadcast flag to 1 while connecting toAP's interfaces are not able get the an ip address hence they are not connecting.
solution:
Added the code to the bridge source code, so that before dropping broadcast packets it first check whether it is dhcp braodcast packet or not. So that it won't drop dhcp broadcast packets. Hence DORA process will succeed and clients which set broadcast flag to 1 gets an ip address even though the proxy arp is enabled.
