Paolo Abeni 47e550e010 veth: refine napi usage
After the previous patch, when enabling GRO, locally generated
TCP traffic experiences some measurable overhead, as it traverses
the GRO engine without any chance of aggregation.

This change refine the NAPI receive path admission test, to avoid
unnecessary GRO overhead in most scenarios, when GRO is enabled
on a veth peer.

Only skbs that are eligible for aggregation enter the GRO layer,
the others will go through the traditional receive path.

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.
