Before that, we've refilled ring even on single descriptor move. Under high packet load that caused page allocation logic to be triggered too often. That made overall ring processing slower. Moreover, with page buffer reuse implemented, we should give a chance higher networking levels to process received packets faster, release the pages they consumed and therefore give a higher chance for these pages to be reused. RX ring is now refilled only when AQ_CFG_RX_REFILL_THRES or more descriptors were processed (32 by default). Under regular traffic this gives quite enough time for packet to be consumed and page to be reused. Signed-off-by: Igor Russkikh <igor.russkikh@aquantia.com> Signed-off-by: David S.

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.
