[dpdk-dev] Fwd: testpmd reports port link down

Hi I have a setup with Intel 82576NS. Port 0 is connected to internal network and is managed by igb driver Port 1 is connected directly to PC which will serve as traffic generator. When Port 1 is managed by igb driver eth interface is configured and I am able to connect to traffic generator PC.

[dpdk-dev] [PATCH] mk: add support for gdb debug info generation

It is often useful to build with debug enabled, we add a config (CONFIG_RTE_TOOLCHAIN_DEBUG) to do so. Note: This patch does not include corresponding changes for ICC. The author pleads abject ignorance in this regard, and welcomes recommendations. :-) Signed-off-by: Cyril Chemparathy ---

[dpdk-dev] [PATCH 6/6] test-pmd: add flowgen forwarding engine

This commit adds a multi-flow traffic generator forwarding engine. In effect, this forwarding mode functions very similar to the txonly mode, with the difference that it generates multiple L4 flows. Signed-off-by: Cyril Chemparathy --- app/test-pmd/Makefile | 1 + app/test-pmd/flowgen.c |

[dpdk-dev] [PATCH 5/6] test-pmd: add mac swap forwarding mode

This commit adds a new forwarding mode, in which the source and destination MAC addresses of packets are swapped before forwarding according to the port-topology in effect. This has been designed for operation primarily with --port-topology=loopback. Signed-off-by: Cyril Chemparathy ---

[dpdk-dev] [PATCH 4/6] test-pmd: allow txpkts to be setup via command line

We allow a new --txpkts command-line parameter to configure segment sizes when in txonly or flowgen forwarding modes. Signed-off-by: Cyril Chemparathy --- app/test-pmd/parameters.c | 57 +++ 1 file changed, 57 insertions(+) diff --git

[dpdk-dev] [PATCH 3/6] test-pmd: allow command line selection of forwarding mode

This commit allows testpmd forwarding mode selection through command line parameters instead of having to set this up in interactive mode. Signed-off-by: Cyril Chemparathy --- app/test-pmd/parameters.c | 4 1 file changed, 4 insertions(+) diff --git a/app/test-pmd/parameters.c

[dpdk-dev] [PATCH 2/6] test-pmd: add support for auto-start when interactive

This patch adds support for a command-line argument --auto-start (-a). When running in interactive mode, this allows us to start traffic without user intervention before dropping to the prompt. Signed-off-by: Cyril Chemparathy --- app/test-pmd/parameters.c | 20

[dpdk-dev] [PATCH 1/6] test-pmd: add support for single port loopback topology

This commits adds a new "loop" option to the --port-topology argument. With the loop option specified, ingress traffic is simply transmitted back on the same interface. Signed-off-by: Cyril Chemparathy --- app/test-pmd/config.c | 16 ++-- app/test-pmd/parameters.c | 2 ++

[dpdk-dev] [PATCH 0/6] Extensions to test-pmd

Hi, This patch series contains a few minor extensions to test-pmd. These changes have been added primarily for convenience while testing out various scenarios with DPDK. Thanks -- Cyril. Cyril Chemparathy (6): test-pmd: add support for single port loopback topology test-pmd: add support

[dpdk-dev] [memnic PATCH] pmd: use rte_atomic32_cmpset instead of cmpxchg

From: Hiroshi Shimamoto Because DPDK has its own compare and set function to optimize to dedicated processor type, use that rte_atomic32_cmpset() instead of cmpxchg macro which is specially introduced for MEMNIC. Signed-off-by: Hiroshi Shimamoto --- common/memnic.h

[dpdk-dev] [memnic PATCH] common: add Dual BSD/GPL license line

From: Hiroshi Shimamoto The MEMNIC header file should be under Dual BSD/GPL license. Put the license text "Dual BSD/GPL" into the file header. Signed-off-by: Hiroshi Shimamoto --- common/memnic.h | 1 + 1 file changed, 1 insertion(+) diff --git a/common/memnic.h
