Chelsio driver loads firmware configuration file to allow

firmware to distribute resources before chip bring up. Chelsio NIC
driver, cxgb4 searches for firmware config file at /lib/firmware/cxgb4/
directory.

Two predefined configuration files are available – default and
hashfilter. Default configuration file equally distributes
resources across all features, such as iSCSI, iWARP, Crypto, etc.
On the other hand, hashfilter configuration file borrows some
resources by disabling the iSCSI, iWARP, Crypto, etc. features,
and redistributes them to increase offloading more number of flows
to hardware via tc-flower.

+#   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.

+# 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.
