[v9,00/12] Packet capture framework enhancements

  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

v9 changes:
  - incorporate suggested change to BPF XOR
  - make autotest for pcapng more complete by reading the
    resulting file with libpcap

v8 changes:
  - enable BPF tests in autotest
  - add more BPF test strings
  - use rte_strscpy to satisfy checkpatch
  - merge MAINTAINERS (put this in with existing pdump)
