9.3 Auto-Negotiation Configuration
NOTE: In NPAR (NIC partitioning) devices where one port is shared by multiple PCI functions, the port speed is
preconfigured and cannot be changed by the driver.
The Broadcom NetXtreme-E controller supports the following auto-negotiation features:
Link speed auto-negotiation
Pause/Flow Control auto-negotiation
NOTE: When using SFP+, SFP28 connectors, use DAC or multimode optical transceivers capable of supporting auto-
negotiation. Ensure that the link partner port has been set to the matching auto-negotiation protocol. For example,
if the local Broadcom port is set to IEEE 802.3by AN protocol, the link partner must support auto-negotiation and
must be set to IEEE 802.3by auto-negotiation protocol. When Media Auto Detect and IEEE 802.by + Consortium
are enabled, the controller uto detects the Ethernet cables and transceivers to start auto-negotiation with the link
partner. FEC is negotiated during auto-negotiation and forced FEC does not take effect in this mode. The default
setting enables IEEE 802.by + Consortium and Media Auto Detect.
