netsniff-ng: Restore tpacket v2 capturing
Some older systems (e.g. RHEL 6) don't have tpacket v3 available, but only tpacket v2. However, since commit d8cdc6a ("ring: netsniff-ng: migrate capture only to TPACKET_V3") we solely rely on tpacket v3 for capturing packets. This patch restores the possibility to capture using tpacket v2. For now this is just a fallback if the configure script doesn't detect tpacket v3 (and thus HAVE_TPACKET3 isn't set). Thus, on most modern systems this shouldn't change anything and they will continue using tpacket v3. For now this fix contains quite a bit of ugly #ifdefery which should be cleaned up in the future. Fixes #76 Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
