[dpdk-dev] [PATCH 1/2 v2] examples/distributor: Fix compile issue

[Michael Qiu]

examples/distributor/main.c(338): error #167:
argument of type "struct rte_mbuf *"
is incompatible with parameter of type "const char *"
_mm_prefetch(bufs[0], 0);

The first param pass to _mm_prefetch is wrong,
need convert "struct rte_mbuf *" to "void *".

Fixes: 07db4a975094 ("examples/distributor: new sample app")

v2 --> v1:
convert "const void *" to "void *" to avoid CLANG issue.
