Patch 1 removes subtable lookup stats from the cycles per
packet stats.
Patch 2:
Correct cycles per packet to be based on packets received
rather than datapath passes.
Add two new stats counters for packet received and packets
recirculated and display these to the user.
Calculate and display to to the user, the average number of
datapath passes per packet.
Make 'miss' counter mean 'ovs miss upcall'.
Annotate the stats display for clarity.
The pmd-stats-show display is significantly changed,
however existing keywords are retained as well as
delimiters, so as to limit impact to scripts, although
no assurance can be made about the impact on all scripts.
Most changes are in Patch 2 as it is easier to understand
the changes given the interrelationship of various fields.
Patch 3 extends the pmd stats test to also test the megaflow
case.
v4->v5: Improve cycles per packet calculation
Add packets received and packets recirculated
counters and display to the user. Add average
number of datapath passes stats display.
Accept review comment to eliminate parameter
passing of a failure stat; increment in caller.
Rename miss_upcall_cnt to upcall_ok_cnt per
review.
miss_no_upcall_cnt was renamed to upcall_fail_cnt.
The new addition of testing megaflow stats is split
out as a separate patch.
v3->v4: Combine patches 2 and 3 because v3 introduced a
dependency.
Also add a OVS_LIKELY in one location.
v2->v3: Fix a bug in patch 2 and fold in review comments.
v1->v2: Add additional patches.
