Follow-ups

Yes. pcap-linux.c include:

#include <net/if.h>

/*

* Got Wireless Extensions?

*/

#ifdef HAVE_LINUX_WIRELESS_H

#include <linux/wireless.h>

#endif

But wireless.h includes:

#include <linux/if.h> /* for IFNAMSIZ and co... */

ifmap and so on is defined in both net/if.h and linux/if.h. That makes the

problem.

Upstream has fixed this bug in:

http://github.com/mcr/libpcap/commit/080c13423a8f37f7b5e0964b6ff1cee2d1d83e0e

http://github.com/mcr/libpcap/commit/ba23aa7b427886224e78408cb1cf48b1cdbe50cc

For us, we simply use linux/if.h to replace net/if.h.
