Backport patch that fixes memory disclosure in packet padding. The downstream driver supports statistics, so when a packet cannot be padded the statistics of dropped packets are incremented. The other patches do not introduce any functional changes.

Subject: [PATCH] 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.
|
|
|
|
This patch is included in OpenWrt for many years.
