From 2eecb2e04abb62ef8ea7b43e1a46bdb5b99d1bf8 Mon Sep 17 00:00:00 2001 From: Yelena Krivosheev Date: Tue, 19 Dec 2017 17:59:47 +0100 Subject: [PATCH] net: mvneta: eliminate wrong call to handle rx descriptor error 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.
