* Removed the unused init function from header processing modules * Added option CHAMELEON_CONF_WITH_MAC_LINK_ADDRESSES to specify that MAC link addresses should be used instead of Chameleon's own encoding of sender and receiver. This avoids encoding the link addresses twice when the MAC RDC has its own addresses.
