Re: [libpcap] TPACKET_V3 support broken when read timeout 0. (#335)

[Michael Richardson <mcr () sandelman ca>]

I propose to release a libpcap 1.5.3 this week with the following changes:

1) if PCAP_LINUX_TPACKET="v3" or ="v2"  then the specific method
   will be used chosen, unless:

2) a new pcap_linux_tpacket(enum method) has been called by the application
   (which having a GUI, I presume) can let the user pick the right answer.

3) failing this, the default will be *v2* for now.

> From the thread on this github issue, my impression is that there might
be a logic error (either a mis-understanding, or a bug) in pcap compared to
the kernel, or it may be that some applications have been doing something
slightly wrong, but up to now, it hasn't mattered.

Having the above controls would let people move forward, and let us gather
enough data to figure out what is up, and fix it.
