The function rte_snprintf serves no useful purpose. It is the same as snprintf() for all valid inputs. Deprecate it and replace all uses in current code. Leave the tests for the deprecated function in place. Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> Acked-by: Thomas Monjalon <thomas.monjalon@6wind.com>
