 shows a diagram of the Mellanox OFED stack, and how upper layer protocols (ULPs) 

interface with the hardware and with the kernel and user space. The application level also shows 
the versatility of markets that Mellanox OFED applies to.

The following sub-sections briefly describe the various components of the Mellanox OFED 
stack.

mlx4

 is the low level driver implementation for the ConnectX family adapters designed by Mel-

lanox Technologies. ConnectX® family adapters can operate as an InfiniBand adapter, or as an 
Ethernet NIC. The OFED driver supports InfiniBand and Ethernet NIC configurations. To 
accommodate the supported configurations, the driver is split into the following modules:

Handles low-level functions like device initialization and firmware commands processing. Also 
controls resource allocation so that the InfiniBand and Ethernet functions can share the device 
without interfering with each other.

Handles InfiniBand-specific functions and plugs into the InfiniBand midlayer
