commit6570bc79c0upstream. Commit323ebb61e3("net: use listified RX for handling GRO_NORMAL skbs") made use of listified skb processing for the users of napi_gro_frags(). The same technique can be used in a way more common napi_gro_receive() to speed up non-merged (GRO_NORMAL) skbs for a wide range of drivers including gro_cells and mac80211 users. This slightly changes the return value in cases where skb is being dropped by the core stack, but it seems to have no impact on related drivers' functionality. gro_normal_batch is left untouched as it's very individual for every single system configuration and might be tuned in manual order to achieve an optimal performance.

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.
