Subject: net: mvneta: eliminate wrong call to handle rx descriptor error
From: Yelena Krivosheev <yelena@xxxxxxxxxxx>
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.
