Subject: [PATCH] VSPERF: Report percentage frameloss from IXIA/IXNET
The patch introduces frame_loss_percent result value.
The implementation is done for Ixia and IxNet
traffic generators. The value is visible in list
of result values at the end of the test, in csv,
rst and md files.
JIRA: VSPERF-201
Change-Id: I9b6795d427b199cb62ed66b7a137e412e36dc757
