libpcap: fix wireless handling
Based on ba23aa7b in libpcap upstream. linux/wireless.h includes linux/if.h, which conflicts with net/if.h as they both define if* structures. Fix build by simply using linux/if.h instead of net/if.h. The same fix should be done for the configure script, but cheat by presetting it instead. This fix in turn fixes kismet build with BR2_CONFIG_CACHE enabled, as that uses the same ac_cv_linux_wireless_h cache value. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
