This is an updated simplified version of previous failsafe xstats
patch and a bug fix for testpmd.

The failsafe xstats patch is almostly a complete redo.

Stephen Hemminger (2):
  app/testpmd: block xstats for hidden ports
  failsafe: implement xstats

All the other testpmd commands block access to devices that
are owned. Looks like xstat got overlooked.

Add support for extended statistics in failsafe driver.
Reports detailed statistics for each sub device.

Example:

testpmd> show port xstats 1
rx_good_packets: 0
tx_good_packets: 0
rx_good_bytes: 0
tx_good_bytes: 0
rx_missed_errors: 0
rx_errors: 0
tx_errors: 0
rx_mbuf_allocation_errors: 0
rx_q0packets: 0
rx_q0bytes: 0
rx_q0errors: 0
tx_q0packets: 0
tx_q0bytes: 0
rx_sub0_good_packets: 0
tx_sub0_good_packets: 0
...
rx_sub1_good_packets: 0
tx_sub1_good_packets: 0
rx_sub1_good_bytes: 0

Hi Stephen, Geatan,

What do you think about adding Stephen as additional failsafe maintainer?
