This is a bug in building the latest version with libpcap/libdnet on
Linux.

May I ask why you are using libdnet/libpcap? I would recommend native
packet socket implementation for Linux builds and if there is something
in the documentation that can be interpreted as saying libdnet/libpcap
would be needed, that should be fixed..

I'll fix the build for CONFIG_DNET_PCAP=y on Linux, but anyway, I would
recommend just removing that option and building with native Linux
packet socket support. That fixes this compilation problem with v0.4.2.
