Virtual eXtensible LAN (VXLAN) – Aware stateless offloads (IP/
UDP/TCP checksum offloads, VLAN insertion/removal, NetQueue,
VMQ, RSS, TCP segmentation offload, Large Send Offload, Generic
Receive Offload).
Supported.
Generic Routing Encapsulation (GRE) – Aware stateless offloads
(IP/UDP/TCP checksum offloads, VLAN insertion/removal, VMQ,
RSS, TCP segmentation offload, Generic Receive Offload).
Supported.
Network Virtualization using Generic Routing Encapsulation
(NVGRE) – Aware stateless offloads (IP/UDP/TCP checksum
offloads, VLAN insertion/removal, VMQ, RSS, Large Send Offload).
Supported.
Generic Network Virtualization Encapsulation (Geneve) – Aware
Stateless offloads (IP/UDP/TCP checksum offloads, VLAN insertion/
removal, NetQueue, RSS, TCP segmentation offload, Generic
Receive Offload).
Supported.
IP-in-IP aware stateless offloads (IP/UDP/TCP checksum offloads,
VLAN insertion/removal, NetQueue, RSS, TCP segmentation
offload, Generic Receive Offload).
Supported.
SR-IOV v1.0 BCM9574XX – 128 Virtual Functions (VFs) for Guest Operating
Systems (GOS) per device. MSI-X vector per VF is set to 16.
BCM9575XX – 1K Virtual Functions (VFs) for Guest Operating
Systems (GOS) per device shared among four ports.
Edge Virtual Bridging (EVB) (IEEE 802.1Qbg) BCM9575XX – Edge Virtual Bridging (EVB) enables switching of
traffic between PFs/VFs, forwarding of outgoing network traffic from
PFs/VFs to appropriate network ports, and steering of incoming
network traffic to appropriate PFs/VFs. Both VEB (local switching in
the NIC) and VEPA (switching in the adjacent switch) EVB modes
of operation are supported. The EVB features supported are:
1K VFs and up to 128 queues per VF (flexible allocation across
PFs/VFs).
PCIe AER, TPH, FLR support.
Virtual Ethernet Bridge (VEB)/Virtual Ethernet Port Aggregator
(VEPA).
MAC/VLAN filtering and mirroring.
VF isolation, source pruning, anti-spoofing checks.
Stateless and packet steering offloads per VF.
Forwarding of unicast frames based on {Tunnel ID (optional),
Destination MAC, VLAN ID (optional)}.
Frame replication for multicast, broadcast, and promiscuous
mode.
Source pruning – Provide support for source knockout (prevent
sending a multicast or broadcast frame back to the source).
Mirroring of traffic to a specific PF or VF.
Packet editing – VLAN insert/swap/delete.
Anti-spoof checks.
MSI-X vector port 74 per port default value (two port configuration). 16 per VF and is
configurable in HII and CCM.
