From: Daniel Inderbitzin Date: Fri, 10 Jul 2015 14:06:02 +0200 Subject: [U-Boot] [PATCH] qoriq eth.c bugfix: handle received corrupted frames correctly Message-ID: <1436529962-3880-1-git-send-email-daniel.inderbitzin@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de From: Daniel Inderbitzin 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.
