This patch set is a more complete version of the the enhanced
packet capture support described last year.
The new capture library and utility are:
- faster avoids lots of extra I/O, does bursting, etc.
- gives more information (multiple ports, queues, etc)
- has a better user interface (same as Wireshark dumpcap)
- fixes structural problems with VLAN's and timestamps
It preserves the old pdump command as is for those people
who never want to change.
v5 changes:
- minor build and checkpatch fixes for RHEL/FreeBSD
- disable lib/pdump on Windows. It was not useful before
and now pdump depends on bpf.
v4 changes:
- minor checkpatch fixes.
Note: some of the checkpatch warnings are bogus and won't be fixed.
- fix build of dumpcap on FreeBSD
v3 changes:
- introduce packet filters using classic BPF to eBPF converter
required small fix to DPDK BPF interpreter
- introduce function to decode eBPF instructions
- add option to dumpcap to show both classic BPF and eBPF result
- drop some un-useful stubs
- minor checkpatch warning cleanup
