- Add new DQO datapath structures: - `gve_rx_buf_queue_dqo` - `gve_rx_compl_queue_dqo` - `gve_rx_buf_state_dqo` - `gve_tx_desc_dqo` - `gve_tx_pending_packet_dqo` - Incorporate these into the existing ring data structures: - `gve_rx_ring` - `gve_tx_ring` Noteworthy mentions: - `gve_rx_buf_state` represents an RX buffer which was posted to HW. Each RX queue has an array of these objects and the index into the array is used as the buffer_id when posted to HW. - `gve_tx_pending_packet_dqo` is treated similarly for TX queues. The completion_tag is the index into the array. - These two structures have links for linked lists which are represented by 16b indexes into a contiguous array of these structures. This reduces memory footprint compared to 64b pointers. - We use unions for the writeable datapath structures to reduce cache footprint. GQI specific members will renamed like DQO members in a future patch.

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.
