Errors-To: dev-bounces@dpdk.org
Many places are using a GCC extension related to variadic macros,
where a name prepends the ellipsis. This results in a warning like
the one below when compiling the code with MSVC:
app\test-pmd\testpmd.h(1314): error C2608:
invalid token '...' in macro parameter list
Variadic macros became a standard part of the C language with C99.
GCC, Clang and MSVC handle them properly.
The fix is to remove the prefix name (args... becomes ...) and use
__VA_ARGS__.
