SetInterfaceInfo picks up the wrong interface #150

Open yilongli opened 7 years ago

yilongli commented 7 years ago

My NIC has two interfaces: eno1 and eno1d1.

The following buggy line will add eno1 to the attached devices even though I have only enabled eno1d1 in the config file. https://github.com/eunyoung14/mtcp/blob/6babf3c75aa73a0c90c005d07e7de27ab6c135ab/mtcp/src/io_module.c#L230

Thanks yilongli. I will look into this issue. Are you using Mellanox devices?

yilongli commented 7 years ago

Yes, I am using Mellanox ConnectX-3 10 GB NIC and Mellanox DPDK.

zorrohahaha commented 5 years ago

Does this support Mellanox ConnectX-4 & DPDK mode?

It should work. Please note that you don't need to insert either igb_uio.ko or dpdk_iface.ko kernel drivers. I should probably update the README file to explain this. I will give you a step-by-step procedure below. Please follow these guidelines:

1- Open up setup_mtcp_dpdk_env.sh and comment (disable) lines 54-63. 2- Next follow the README file. 3- Instead of using dpdk0 interface, you should use the actual name of the Ethernet interface as seen from ifconfig command. 4- Finally, you should replace the mTCP configuration (e.g. epserver.conf) lines port = dpdk0 to port = <intf_name> where <intf_name> is the actual name of the Ethernet interface as seen from ifconfig command. You should do the same thing for the line: stat_print.

Please let me know if you have any other follow-up questions. I will update the file to include these guidelines soon.
