V2->V3: - The command implementation is changed so that the queuestate does not depend on the command execution. V1->V2: - use Tx instead of TX - add note in doc --- app/test-pmd/cmdline.c | 88 +++++++++++++++++++++++++++++ doc/guides/rel_notes/release_21_05.rst | 2 + doc/guides/testpmd_app_ug/testpmd_funcs.rst | 9 +++ 3 files changed, 99 insertions(+) diff --git a/app/test-pmd/cmdline.c b/app/test-pmd/cmdline.c index ccaeefa..d63cd49 100644 --- a/app/test-pmd/cmdline.c +++ b/app/test-pmd/cmdline.c @@ -905,6 +905,9 @@ static void cmd_help_long_parsed(void *parsed_result, " Register a dynf and Set/clear this flag on Tx.
