Tests showed that when whole bandwidth is consumed, the latency for various kind of traffic can reach high values. With saturated link (e.g. with iperf from target to host) simple ping could take significant amount of time. BQL proved to improve this situation when implemented in mvneta driver. Measurements of ping latency for 3 link speeds: Speed | Latency w/o BQL | Latency with BQL 10 | 7-14 ms | 3.5 ms 100 | 2-12 ms | 0.6 ms 1000 | often timeout | up to 2ms Decreasing latency as above result in sligt performance cost - 4kpps (-1.4%) when pushing 64B packets via two bridged interfaces of Armada 38x. For 1500B packets in the same setup, the mpstat tool showed +8% of CPU occupation (default affinity, second CPU idle). Even though this cost seems reasonable to take, considering other improvements. This commit adds byte queue limit mechanism for the mvneta driver. Signed-off-by: Marcin Wojtas <mw@semihalf.com> Signed-off-by: David S. Miller <davem@davemloft.net> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
