Commit Message

Ciara Loftus Feb. 2, 2021, 1:36 p.m. UTC 
Prior to this, the packet count was fixed at 10000 for every test.
Future tracing tests need to modify the count in order to ensure
the trace buffer does not become full. So, make it possible to set
the count from test_xsk.h using the -C opt.
