When cmdline option '--max-pkt-len' set the value less then\n '1500 + overhead', the app/testpmd will force to resize the 'max-pkt-len'\n to '1500 + overhead'. However, the user really want to configure\n 'max-pkt-len' to a specified value (< 1500 + overhead);\n\n2. If the large value of '--max-pkt-len' gave (e.g.: 8000), and user want to\n reset the value to a small one (e.g.: 1400), it will became invalid due to\n JUMBO_FRAME offload state doesn't change before port started;\n\n3. When rx/tx queue offloads capabilities aren't specified, the rx/tx queue\n setup will be failed once the port offloads changed.\n\n---\nv4:\n * combined testpmd patches;\n * updated the commit log for patch 2;\nv3:\n * rebased code to latest;\n * splited to 3 commits;\n\nv2:\n * moved the update logic to 'rxtx_port_config';\n * added the 'tx_conf' part;\n * optimized the 'default' assignment;\n---\n\nSteve Yang (2):\n ethdev: fix MTU doesn't update when jumbo frame disabled\n app/testpmd: fix max-pkt-len option invalid\n\n app/test-pmd/cmdline.c | 1 +\n app/test-pmd/parameters.c | 1 +\n app/test-pmd/testpmd.c | 63 +++++++++++++++++++++++++---------\n app/test-pmd/testpmd.h | 2 ++\n lib/librte_ethdev/rte_ethdev.c | 8 ++---\n 5 files changed, 54 insertions(+), 21 deletions(-)" }
