Currently, if skb is non-linear, due to MHI skb chaining, it is linearized in MBIM RX handler prior MBIM decoding, causing extra allocation and copy that can be as large as the maximum MBIM frame size (32K). This change introduces MBIM decoding for non-linear skb, allowing to process 'large' non-linear MBIM packets without skb linearization. The IP packets are simply extracted from the MBIM frame using the skb_copy_bits helper. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
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.
