Teaming with

Channel Bonding

With the Linux drivers, you can team adapters together using the bonding
kernel module and a channel bonding interface. For more information, see
the Channel Bonding information in your operating system documentation.

Statistics

You can view detailed statistics and configuration information using the
ethtool utility. See the ethtool man page for more information.
