-# Chelsio T6 Factory Default configuration file.
+# Firmware configuration file.
 #
-# Copyright (C) 2014-2016 Chelsio Communications.  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 2-port T6-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 0-1 on PF0-1, 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:
-#
-#         2 ports *
-#         3 application functions (NIC, FCoE, iSCSI) per port *
-#         16 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.
