Linux kernel source tree

It is suboptimal to attempt skb linearization from ndo_start_xmit() if a gso skb has pathological layout, or if host stack does not have access to the payload (TCP direct). Linearization of large skbs can also fail under memory pressure. We should instead have an ndo_features_check() so that we can fallback to GSO, which is supported even for TCP direct, and generally much more efficient (no payload copy).

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.
