+Subject: net: ethernet: lantiq_etop: fix memory disclosure
+
+When applying padding, the buffer is not zeroed, which results in memory
+disclosure. The mentioned data is observed on the wire. This patch uses
+skb_put_padto() to pad Ethernet frames properly. The mentioned function
+zeroes the expanded buffer.
+
+In case the packet cannot be padded it is silently dropped. Statistics
+are also not incremented. This driver does not support statistics in the
+old 32-bit format or the new 64-bit format. These will be added in the
+future. In its current form, the patch should be easily backported to
+stable versions.
+
+Ethernet MACs on Amazon-SE and Danube cannot do padding of the packets
+in hardware, so software padding must be applied.
+
+Fixes: 504d4721ee8e ("MIPS: Lantiq: Add ethernet driver")

-
-The size of the internal RAM of the DesignWare USB controller changed

-Amazon + Danube: 8 KByte
-Amazon SE + arx100: 2 KByte
-xrx200 + xrx300: 2.5 KByte

-For Danube SoC we do not provide the params and let the driver decide
-to use sane defaults, for the Amazon SE and arx100 we use small fifos
-and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
-The auto detection of max_transfer_size and max_packet_count should
-work, so remove it.

-Subject: [PATCH 2/2] MIPS: lantiq: improve USB initialization
-
-This adds code to initialize the USB controller and PHY also on Danube,
-Amazon SE and AR10. This code is based on the Vendor driver from
-different UGW versions and compared to the hardware documentation.
