Description

EthernetFace obtains a file descriptor from pcap_get_selectable_fd API, and passes it to Boost.Asio.

On OS X and FreeBSD, Boost.Asio uses kqueue as an alternate to poll syscall, in order to gain better performance.

Since Boost 1.56, Boost.Asio's usage of kqueue becomes incompatible with libpcap's file descriptor.
Attempting to create an EthernetFace causes runtime error.

Although it's possible to disable kqueue and revert to poll syscall, the performance would be worse than using kqueue.

Therefore, EthernetFace is forcibly disabled on platforms with kqueue, when NFD is compiled with Boost 1.56 or above.

This Task is to find a workaround, so that EthernetFace can work with kqueue and Boost 1.56.0.
