NVGRE Offload

Chelsio's T5 based adapters are uniquely capable of offloading the processing of NVGRE
encapsulated frames such that all stateless offloads (checksums, LSO, VMQ and filtering) are
preserved, resulting in significant performance benefits. This feature is enabled by default.
Configure the relevant customer and provider network settings on the host.
2.4.

VXLAN Task Offload

Virtual Extensible LAN (VXLAN), an extension of the existing VLAN protocol, is an
encapsulation protocol which creates an overlay network on the existing Layer 3 infrastructure.
VXLAN not only extends VLAN's Ethernet Layer 2 network services but also provides more
extensibility, flexibility and scalability for large scale cloud deployments than VLAN.
Chelsio's T5 based adapters are capable of offloading the processing of VXLAN encapsulated
frames such that all stateless offloads (checksums, LSO, VMQ, RSS and filtering) are
preserved, resulting in significant performance benefits. This feature is enabled by default.
2.5.

PacketDirect

PacketDirect Provider Interface (PDPI), an extension to the existing NDIS miniport driver model,
gives applications complete control over buffers, poll processors, and sending and receiving
packets over a miniport adapter.
Chelsio's T5 based adapters offer extensive support for this feature leading to a higher
throughput performance. This feature is enabled by default.
