4.17-stable review patch. If anyone has any objections, please let me know. ------------------ From: Adrian Hunter <adrian.hunter@xxxxxxxxx> commit bd2e49ec48feb1855f7624198849eea4610e2286 upstream. It is possible to have a CBR packet between a FUP packet and corresponding TIP packet. Stop treating it as an error.
