Add ETHER_BROADCAST and DEFAULT_LINK_MTU constants.
ETHER_BROADCAST is used to fill the destination mac address of ether
header, it was defined in the DhcpPacket.java, move it to a common
place for other usecases.
Also have a link mtu constant(default value is 1500 bytes), irrelevant
to specific link-layer type.
