4.9-stable review patch. If anyone has any objections, please let me know.
------------------ From: Yelena Krivosheev <[email protected]> commit 2eecb2e04abb62ef8ea7b43e1a46bdb5b99d1bf8 upstream. There are few reasons in mvneta_rx_swbm() function when received packet is dropped. mvneta_rx_error() should be called only if error bit [16] is set in rx descriptor.
