Michal Pecio a8749742e6 net: usb: rtl8150: Fix frame padding
commit 75cea9860aa6b2350d90a8d78fed114d27c7eca2 upstream.

TX frames aren't padded and unknown memory is sent into the ether.

Theoretically, it isn't even guaranteed that the extra memory exists
and can be sent out, which could cause further problems. In practice,
I found that plenty of tailroom exists in the skb itself (in my test
with ping at least) and skb_padto() easily succeeds, so use it here.

In the event of -ENOMEM drop the frame like other drivers do.

The use of one more padding byte instead of a USB zero-length packet
is retained to avoid regression. I have a dodgy Etron xHCI controller
which doesn't seem to support sending ZLPs at all.

README

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
