(better approach to mobile ad-hoc networking) is a routing protocol for multi-hop ad-hoc mesh networks. The networks may be wired or wireless.

The next version of checkpatch.pl warns about the usage of __attribute__((packed))). Linux 2.6.33 defines an extra macro __always_unused which is used to assist source code analyzers and can be used to removed the last existing __attribute__ inside the source code.
