From: Alexander Kozyrev Date: Wed, 23 Feb 2022 03:02:39 +0000 (+0200) Subject: app/testpmd: add flow queue pull operation X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=f9bf7dff5d88f5c96991c4d9091ab4562443fb1c;p=dpdk.git app/testpmd: add flow queue pull operation Add testpmd support for the rte_flow_pull API. Provide the command line interface for pulling operations results. Usage example: flow pull 0 queue 0 Signed-off-by: Alexander Kozyrev Acked-by: Ori Kam --- diff --git a/app/test-pmd/cmdline_flow.c b/app/test-pmd/cmdline_flow.c index af36975cdf..d4b72724e6 100644 --- a/app/test-pmd/cmdline_flow.c +++ b/app/test-pmd/cmdline_flow.c @@ -95,6 +95,7 @@ enum index { FLEX, QUEUE, PUSH, + PULL, /* Flex arguments */ FLEX_ITEM_INIT, @@ -142,6 +143,9 @@ enum index { /* Push arguments. */ PUSH_QUEUE, + /* Pull arguments. */ + PULL_QUEUE, + /* Table arguments. */ TABLE_CREATE, TABLE_DESTROY, @@ -2259,6 +2263,9 @@ static int parse_qo_destroy(struct context *, const struct token *, static int parse_push(struct context *, const struct token *, const char *, unsigned int, void *, unsigned int);
