linux-stable.git/drivers/net/usb, branch v3.12.9 Linux kernel stable tree dm9601: work around tx fifo sync issue on dm962x 2014-01-09T20:25:12+00:00 Peter Korsgaard peter@korsgaard.com 2013-12-16T10:35:35+00:00 4734753a6e323b73a89bf9d47375efac3ab70ea6 commit 4263c86dca5198da6bd3ad826d0b2304fbe25776 upstream. 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.

commit 4263c86dca5198da6bd3ad826d0b2304fbe25776 upstream.

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.
