     #   DO NOT MODIFY THIS FILE UNDER ANY CIRCUMSTANCES.  MODIFICATION OF
     #   THIS FILE WILL RESULT IN A NON-FUNCTIONAL T4 ADAPTER AND MAY RESULT
     #   IN PHYSICAL DAMAGE TO T4 ADAPTERS.
     
     # This file provides the default, power-on configuration for 4-port T4-based
    # adapters shipped from the factory.  These defaults are designed to address
    # the needs of the vast majority of T4 customers.  The basic idea is to have
    # a default configuration which allows a customer to plug a T4 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 T4 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: 128.
    #  2. Ingress Queues with Free Lists: 1024.  PCI-E SR-IOV Virtual Functions
    #     must use a power of 2 Ingress Queues.
    #  3. Egress Queues: 128K.  PCI-E SR-IOV Virtual Functions must use a
    #     power of 2 Egress Queues.
    #  4. MSI-X Vectors: 1088.  A complication here is that the PCI-E SR-IOV
    #     Virtual Functions based off of a Physical Function all get the
    #     same umber of MSI-X Vectors as the base Physical Function.
    #     Additionally, regardless of whether Virtual Functions are enabled or
    #     not, their MSI-X "needs" are counted by the PCI-E implementation.
    #     And finally, all Physical Funcations capable of supporting Virtual
    #     Functions (PF0-3) must have the same number of configured TotalVFs in
    #     their SR-IOV Capabilities.
    #  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 PF0 but it could be any Physical Function).  Thus,
    #     this "Unified PF"  will need to have enough resources allocated to it
    #     to allow for this.  And because of the MSI-X resource allocation
    #     constraints mentioned above, this probably means we'll either have to
    #     severely limit the TotalVFs if we continue to use PF0 as the Unified PF
    #     or we'll need to move the Unified PF into the PF4-7 range since those
    #     Physical Functions don't have any Virtual Functions associated with
    #     them.
    #  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 T4's PCI-E SR-IOV Capability to allow
    #     Virtual Machines to directly access T4 functionality via SR-IOV
    #     Virtual Functions and "PCI Device Passthrough" -- this is especially
    #     true for the NIC application functionality.  (Note that there is
    #     currently no ability to use the TOE, FCoE, iSCSI, etc. via Virtual
    #     Functions so this is in fact solely limited to NIC.)
