Hi Huisong Li,
Yes it would apply, but it would not build.
On 19.11 there would still be uses of portid_t  pt_id left and since
in this patch it was removed from start_packet_forwarding it breaks
the build.
Just adding back the variable as a backport without further
investigation if that really would work out well and some testing
seemed too risky.
