From 466f775e02bcde5ea7454cd73ecf1a0f79275a30 Mon Sep 17 00:00:00 2001 From: Daniel Inderbitzin Date: Fri, 10 Jul 2015 14:06:02 +0200 Subject: qoriq eth.c bugfix: handle received corrupted frames correctly The rxbd is not correctly handled in case of a frame physical error (FPE) or frame size error (FSE). The rxbd must be cleared and advanced in case of an error to avoid receive stall.
