Hello,

We have a requirement to improve the data-transfer on a Linux server (through Ethernet interface with 1 Gbps). We are wondering to add one similar Ethernet interface, trunck (teaming) it existing interface, so that we can get bigger pipe (2 Gbps) for data transfer. Is that possible? If yes, please provide me the steps to do it. Thanks !
