Parsing command line for rte_flow_action_prog. Syntax:
"prog name <name> [arguments <arg_name_0> <arg_value_0> \ <arg_name_1> <arg_value1> ... end]" Use parse_string0 to parse name string. Use parse_hex to parse hex string. Use struct action_prog_data to store parsed result. Example: Action with 2 arguments: "prog name action0 arguments field0 03FF field1 55AA end" Action without argument: "prog name action1" Signed-off-by: Qi Zhang <qi.z.zh...@intel.com> --- v2: - fix title - minor coding style refine. app/test-pmd/cmdline_flow.c | 230 ++++++++++++++++++++++++++++++++++++ 1 file changed, 230 insertions(+) diff --git a/app/test-pmd/cmdline_flow.c b/app/test-pmd/cmdline_flow.c index 21828c144c..c11b756360 100644 --- a/app/test-pmd/cmdline_flow.c +++ b/app/test-pmd/cmdline_flow.c @@ -719,6 +719,13 @@ enum index { ACTION_IPV6_EXT_PUSH, ACTION_IPV6_EXT_PUSH_INDEX, ACTION_IPV6_EXT_PUSH_INDEX_VALUE, + ACTION_PROG, + ACTION_PROG_NAME, + ACTION_PROG_NAME_STRING, + ACTION_PROG_ARGUMENTS, + ACTION_PROG_ARG_NAME, + ACTION_PROG_ARG_VALUE, + ACTION_PROG_ARG_END, };
