LLDPLink Layer Discovery Protocol, IEEE802.1AB
LUNLogical Unit Number (LUN) is the identifier of a device which is being addressed by protocols such as Fibre Channel and iSCSI
MPAMarker Based PDU Alignment. This protocol runs on top of TCP and provides framing and data integrity.
Native OS StackOS stack that represents a particular function implemented purely in software (e.g., native OS TCP/IP stack, native OS iSCSI stack).
Native TCP/IP StackTCP/IP stack implemented in software and provided as part of the operating system.
NFSNetwork File System
NICNetwork Interface Controller
ODMOffload Device Manager
Offload Stack Components that make up the offload stack
OPSOffload Protocol Switch
Packet BuffersPacket buffers are hardware FIFOs that either receive or transmit packets. Each packet buffer can be associated with one or more traffic classes
PCIPeripheral Components Interface
PDUProtocol Data Unit
PFCPriority Flow Control
Raw Packet DriverStandard Ethernet MAC driver.
RDMARemote Direct Memory Access

RSSReceive Side Scaling is a mechanism for hardware to distribute receive packets to queues that are associated with a specific processor core and thereby distributing the processing load.
RXReceive
SANStorage Area Network
SCSISmall Computer System Interface
SNMPSimple Network Management Protocol
TLVType Length Value
Transport InterfaceInterface to the chip at the transport layer.
TXTransmit
ULPUpper Layer Protocol
VBDVirtual Bus Driver. Driver that exposes two virtual physical Devices on a single physical device and enables sharing of LAN and SAN traffic on a common Ethernet port.
VFTVirtual Fabric Tagging is a Fibre Channel defined extended frame header.
VMDqVirtual Machine Device Queues
VLANVirtual LAN (VLAN) is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location.
VTVanderpool Technology, also known as Virtualization. VT is an Intel-wide effort to support multiple virtual platforms on a single physical platform. This requires both software and hardware support to implement efficiently.
