net: introduce packet capture support
Add support for capturing ethernet packets and storing
them in memory in PCAP(2.4) format, later to be analyzed by
any PCAP viewer software (IE. Wireshark)
This feature greatly assist debugging network issues such
as detecting dropped packets, packet corruption etc.
