The RX path allocates the QPL page pool at queue creation, and tries to reuse these pages through page recycling. This patch ensures that on refill no non-QPL pages are posted to the device. When the driver is running low on free buffers, an ondemand allocation step kicks in that allocates a non-qpl page for SKB business to free up the QPL page in use. gve_try_recycle_buf was moved to gve_rx_append_frags so that driver does not attempt to mark buffer as used if a non-qpl page was allocated ondemand.

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.
