If NETIF_F_GRO_HW is disabled, the existing driver code uses kmalloc'ed data for RX buffers. This causes inefficient SW GRO performance because the GRO data is merged using the less efficient frag_list. Use netdev_alloc_frag() and friends instead so that GRO data can be merged into skb_shinfo(skb)->frags for better 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.
