All rights reserved. +# +# DO NOT MODIFY THIS FILE UNDER ANY CIRCUMSTANCES. MODIFICATION OF THIS FILE +# WILL RESULT IN A NON-FUNCTIONAL ADAPTER AND MAY RESULT IN PHYSICAL DAMAGE +# TO ADAPTERS. + + +# This file provides the default, power-on configuration for 4-port T5-based +# adapters shipped from the factory. These defaults are designed to address +# the needs of the vast majority of Terminator customers. The basic idea is to +# have a default configuration which allows a customer to plug a Terminator +# adapter in and have it work regardless of OS, driver or application except in +# the most unusual and/or demanding customer applications. +# +# Many of the Terminator resources which are described by this configuration +# are finite. This requires balancing the configuration/operation needs of +# device drivers across OSes and a large number of customer application. +# +# Some of the more important resources to allocate and their constaints are: +# 1. Virtual Interfaces: 256. +# 2. Ingress Queues with Free Lists: 1024. +# 3. Egress Queues: 128K. +# 4. MSI-X Vectors: 1088. +# 5. Multi-Port Support (MPS) TCAM: 336 entries to support MAC destination +# address matching on Ingress Packets. +# +# Some of the important OS/Driver resource needs are: +# 6. Some OS Drivers will manage all resources through a single Physical +# Function (currently PF4 but it could be any Physical Function). +# 7. Some OS Drivers will manage different ports and functions (NIC, +# storage, etc.) on different Physical Functions. For example, NIC +# functions for ports 0-3 on PF0-3, FCoE on PF4, iSCSI on PF5, etc. +# +# Some of the customer application needs which need to be accommodated: +# 8. Some customers will want to support large CPU count systems with +# good scaling. Thus, we'll need to accommodate a number of +# Ingress Queues and MSI-X Vectors to allow up to some number of CPUs +# to be involved per port and per application function. For example, +# in the case where all ports and application functions will be +# managed via a single Unified PF and we want to accommodate scaling up +# to 8 CPUs, we would want: +# +# 4 ports * +# 3 application functions (NIC, FCoE, iSCSI) per port * +# 8 Ingress Queue/MSI-X Vectors per application function +# +# for a total of 96 Ingress Queues and MSI-X Vectors on the Unified PF. +# (Plus a few for Firmware Event Queues, etc.) +# +# 9. Some customers will want to use PCI-E SR-IOV Capability to allow Virtual +# Machines to directly access T6 functionality via SR-IOV Virtual Functions +# and "PCI Device Passthrough" -- this is especially true for the NIC +# application functionality. +# + + +# Global configuration settings. +# +[global] + rss_glb_config_mode = basicvirtual + rss_glb_config_options = tnlmapen,hashtoeplitz,tnlalllkp + + # PL_TIMEOUT register + pl_timeout_value = 10000 # the timeout value in units of us + + # The following Scatter Gather Engine (SGE) settings assume a 4KB Host + # Page Size and a 64B L1 Cache Line Size.
