OK, I'd vote for an environment variable, so as not to

        1) add a new API that would implement platform-specific behavior (which would encourage people to use it, 
rather than getting the underlying problems fixed);

        2) require that programs *using* libpcap add code to use that API and provide UI to specify platform-dependent 
options to control the capture mechanism.

Hopefully the environment variable will also be annoying enough to use that people will report problems such as the 
TPACKET_V3 problems and, if they require OS fixes, put pressure on developers to get them fixed, rather than having 
tweaking capture options such as that being "the new normal".
