[dpdk-dev] [PATCH 2/5] examples/l3fwd: fix compilation with clang 3.5

[Olivier Matz <olivier.matz@6wind.com>]

Fix the following error:
  error: unused function 'l3fwd_simple_forward'

The l3fwd_simple_forward() is maybe unused, due to compilation options
(APP_LOOKUP_METHOD, ENABLE_MULTI_BUFFER_OPTIMIZE). As the combinatorial
is quite big, it looks simpler to add the __attribute__((unused)) on
this function, so that the compiler does not complain.
