> Subject: [PATCH v1] ethdev: fix address sanitizer bug
> 
> With clang 10 compilation, the address sanitizer reports global buffer
> overflow issue. The issue is observed during trace point registration in
> rte_trace_point_emit_string, for strings in iterator structure.
> As a workaround for this clang issue, this patch removes the
> rte_trace_point_emit_string and instead adds rte_trace_point_emit_ptr to
> capture the iterator pointer.
