Vmxnet3 uses the following debug macro style:
#ifdef SOME_DEBUG
# define debug(...) do{ printf(...); } while (0)
# else
# define debug(...) do{ } while (0)
#endif
If SOME_DEBUG is undefined, then format string inside the
debug macro will never be checked by compiler. Code is
likely to break in the future when SOME_DEBUG is enabled
because of lack of testing. This patch changes this
to the following:
#define debug(...) \
do { if (SOME_DEBUG_ENABLED) printf(...); } while (0)
