4.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Christophe Ricard <christophe.ric...@gmail.com> commit 8b706884eac958ec16518315053f77e052627084 upstream. PCB_SYNC different than PCB_TYPE_SUPERVISOR or PCB_TYPE_DATAFRAME should be discarded. Irrelevant data may be forwarded up to the ndlc state machine by phys like spi to prevent missing potential data during "write" transactions.
