From 4263c86dca5198da6bd3ad826d0b2304fbe25776 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Mon, 16 Dec 2013 11:35:35 +0100 Subject: [PATCH] dm9601: work around tx fifo sync issue on dm962x Certain dm962x revisions contain an bug, where if a USB bulk transfer retry (E.G. if bulk crc mismatch) happens right after a transfer with odd or maxpacket length, the internal tx hardware fifo gets out of sync causing the interface to stop working. Work around it by adding up to 3 bytes of padding to ensure this situation cannot trigger. This workaround also means we never pass multiple-of-maxpacket size skb's to usbnet, so the length adjustment to handle usbnet's padding of those can be removed.
