Detailed Description

Linux-specific EthernetPacketBackend readiness tests.

Exercises the Linux implementation that connects the libpcap selectable descriptor, when available, to an Asio POSIX stream descriptor. On Linux installations where libpcap cannot expose a selectable descriptor, the same tests exercise the documented polling fallback instead.
