tcpreplay causes OS X WiFi to disassociate from AP

[aturner]

There's a bug in the OS X kernel or driver which causes the interface to disassociate from the AP when pcap_findalldevs() is called. I've opened Apple Bug ID# 5152213. Hopefully this will get fixed in 10.4.10 or so. Until then, I'll see about trying to not call this function.

Guy Harris has informed me that libpcap 0.9.6 should have a fix for this. Hence, I should be able to do a libpcap version detection to optionally enable this code rather then just turning it off for all OS X.

(In [1839]) don't use pcap_findalldevs() on OS X. refs #167

I should backout this patch after libpcap 0.9.6 is released.

(In [1845]) svn merge -r 1838:1839 ../../trunk . merges r1839 to 3.0. fixes #167

Crap. 0.9.6 thinks it's 0.9.5, so there's no way to detect if the fix is installed. Hence, we'll have to wait until 0.9.7 and hope they fix the VERSION string then.

(In [1871]) detect libpcap >= 0.9.6 which fixes wlan disassociation issue under OS X. fixes #167
