It's INT_MAX value which means that speed is unknown. To simplify processing of the value in application, new function is added which convert link_speed to string. Also dpdk examples have many duplicated code which format entire link status structure to text. This commit adds two functions: * rte_eth_link_speed_to_str - format link_speed to string * rte_eth_link_to_str - convert link status structure to string Signed-off-by: Ivan Dyukov --- MAINTAINERS | 1 + app/test/Makefile | 3 + app/test/meson.build | 2 + app/test/test_ethdev_link.c | 169 +++++++++++++++++++++++ lib/librte_ethdev/rte_ethdev.c | 53 +++++++ lib/librte_ethdev/rte_ethdev.h | 32 +++++ lib/librte_ethdev/rte_ethdev_version.map | 4 + 7 files changed, 264 insertions(+) create mode 100644 app/test/test_ethdev_link.c diff --git a/MAINTAINERS b/MAINTAINERS index 5e706cd7e..f4fb31ea2 100644 --- a/MAINTAINERS +++ b/MAINTAINERS @@ -393,6 +393,7 @@ T: git://dpdk.org/next/dpdk-next-net F: lib/librte_ethdev/ F: devtools/test-null.sh F: doc/guides/prog_guide/switch_representation.rst +F: app/test/test_ethdev* Flow API M: Ori Kam diff --git a/app/test/Makefile b/app/test/Makefile index e5440774b..9f43b8c3c 100644 --- a/app/test/Makefile +++ b/app/test/Makefile @@ -251,6 +251,9 @@ SRCS-$(CONFIG_RTE_LIBRTE_SECURITY) += test_security.c SRCS-$(CONFIG_RTE_LIBRTE_IPSEC) += test_ipsec.c test_ipsec_perf.c SRCS-$(CONFIG_RTE_LIBRTE_IPSEC) += test_ipsec_sad.c + +SRCS-$(CONFIG_RTE_LIBRTE_ETHER) += test_ethdev_link.c + ifeq ($(CONFIG_RTE_LIBRTE_IPSEC),y) LDLIBS += -lrte_ipsec endif diff --git a/app/test/meson.build b/app/test/meson.build index 56591db4e..1e6acf701 100644 --- a/app/test/meson.build +++ b/app/test/meson.build @@ -39,6 +39,7 @@ test_sources = files('commands.c', 'test_efd.c', 'test_efd_perf.c', 'test_errno.c', + 'test_ethdev_link.c', 'test_event_crypto_adapter.c', 'test_event_eth_rx_adapter.c', 'test_event_ring.c', @@ -199,6 +200,7 @@ fast_tests = [ ['eal_flags_misc_autotest', false], ['eal_fs_autotest', true], ['errno_autotest', true], + ['ethdev_link_status', true], ['event_ring_autotest', true], ['fib_autotest', true], ['fib6_autotest', true], diff --git a/app/test/test_ethdev_link.c b/app/test/test_ethdev_link.c new file mode 100644 index 000000000..1c6b0c9ed --- /dev/null +++ b/app/test/test_ethdev_link.c @@ -0,0 +1,169 @@ +/* SPDX-License-Identifier: BSD-3-Clause + * Copyright (c) 2020 Samsung Electronics Co., Ltd All Rights Reserved + */ + +#include +#include + +#include +#include "test.h" + + +static int32_t +test_link_status_up_default(void) +{ + int ret = 0;
