# 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.
#
