Linux kernel source tree

The driver currently uses page_pool_put_page() to recycle
page pool pages. Since gve uses split pages, if the fragment
being recycled is not the last fragment in the page, there
is no dma sync operation. When the last fragment is recycled,
dma sync is performed by page pool infra according to the
value passed as dma_sync_size which right now is set to the
size of fragment.
But the correct thing to do is to dma sync the entire page when
the last fragment is recycled. Hence change to using
page_pool_put_full_page().

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 reStructuredText 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.
