Chapter X. Offload Bonding driver

1. Introduction

The Chelsio Offload bonding driver provides a method to aggregate multiple network interfaces

into a single logical bonded interface effectively combining the bandwidth into a single

connection. It also provides redundancy in case one of link fails.

The traffic running over the bonded interface can be fully offloaded to the T4 Adapter, thus

freeing the CPU from TCP/IP overhead.
