| Series | [ovs-dev,v10,1/3] netdev-dpdk: Reuse vhost function for dpdk ETH custom stats. | expand |
Hi, Please review the patch set v10. Changes since v9 : Patch - 1: Fixed the issue with index inside the for loop for copying the dpdk extended stats inside 'netdev_dpdk_get_custom_stats' function. Patch - 2: Modified the commit message. Changed the custom stats prefix from 'netdev_dpdk_' to 'ovs_' Added note about the prefix 'ovs_' in dpdk documentation. Addressed other comments given by Kevin. Thanks & Regards, Sriram. -----Original Message----- From: Sriram Vatala <sriram.v@altencalsoftlabs.com> Sent: 24 October 2019 23:51 To: ovs-dev@openvswitch.org; i.maximets@ovn.org; ktraynor@redhat.com Cc: Ilya Maximets <i.maximets@samsung.com>; Sriram Vatala <sriram.v@altencalsoftlabs.com> Subject: [PATCH v10 1/3] netdev-dpdk: Reuse vhost function for dpdk ETH custom stats. From: Ilya Maximets <i.maximets@samsung.com> This is yet another refactoring for upcoming detailed drop stats. It allowes to use single function for all the software calculated statistics in netdev-dpdk for both vhost and ETH ports. UINT64_MAX used as a marker for non-supported statistics in a same way as it's done in bridge.c for common netdev stats.
