Marko Kovacevic - Jan. 11, 2019, 4:52 p.m.
Added unit test to check if a SGL buffer
was added as an input and a Linear Buffer
as output and vice versa so we can test if the
application would process the different buffers
properly.

v4:
  Added Acks resolved checkpatch issue
V3:
  Merged test into sgl test to make
  it all into one
