[ Upstream commit 4ce62d5b2f7aecd4900e7d6115588ad7f9acccca ]
Some usb drivers try to set small skb->truesize and break
core networking stacks.
In this patch, I removed one of the skb->truesize overide.
I also replaced one skb_clone() by an allocation of a fresh
and small skb, to get minimally sized skbs, like we did
in commit 1e2c611723 ("net: cdc_ncm: reduce skb truesize
in rx path")
Fixes: f8ebb3ac881b ("net: usb: ax88179_178a: Fix packet receiving")

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
