7#   IN PHYSICAL DAMAGE TO T4 ADAPTERS.

9# This file provides the default, power-on configuration for 4-port T4-based
10# adapters shipped from the factory.  These defaults are designed to address
11# the needs of the vast majority of T4 customers.  The basic idea is to have
12# a default configuration which allows a customer to plug a T4 adapter in and
13# have it work regardless of OS, driver or application except in the most
14# unusual and/or demanding customer applications.
15#
16# Many of the T4 resources which are described by this configuration are
17# finite.  This requires balancing the configuration/operation needs of
18# device drivers across OSes and a large number of customer application.
19#
20# Some of the more important resources to allocate and their constaints are:
21#  1. Virtual Interfaces: 128.
22#  2. Ingress Queues with Free Lists: 1024.  PCI-E SR-IOV Virtual Functions
23#     must use a power of 2 Ingress Queues.
24#  3. Egress Queues: 128K.  PCI-E SR-IOV Virtual Functions must use a
25#     power of 2 Egress Queues.
26#  4. MSI-X Vectors: 1088.  A complication here is that the PCI-E SR-IOV
27#     Virtual Functions based off of a Physical Function all get the
28#     same umber of MSI-X Vectors as the base Physical Function.
29#     Additionally, regardless of whether Virtual Functions are enabled or
30#     not, their MSI-X "needs" are counted by the PCI-E implementation.
31#     And finally, all Physical Funcations capable of supporting Virtual
32#     Functions (PF0-3) must have the same number of configured TotalVFs in
33#     their SR-IOV Capabilities.
34#  5. Multi-Port Support (MPS) TCAM: 336 entries to support MAC destination
35#     address matching on Ingress Packets.
36#
37# Some of the important OS/Driver resource needs are:
38#  6. Some OS Drivers will manage all resources through a single Physical
39#     Function (currently PF0 but it could be any Physical Function).  Thus,
40#     this "Unified PF"  will need to have enough resources allocated to it
41#     to allow for this.  And because of the MSI-X resource allocation
42#     constraints mentioned above, this probably means we'll either have to
43#     severely limit the TotalVFs if we continue to use PF0 as the Unified PF
44#     or we'll need to move the Unified PF into the PF4-7 range since those
45#     Physical Functions don't have any Virtual Functions associated with
46#     them.
47#  7. Some OS Drivers will manage different ports and functions (NIC,
48#     storage, etc.) on different Physical Functions.  For example, NIC
49#     functions for ports 0-3 on PF0-3, FCoE on PF4, iSCSI on PF5, etc.
50#
51# Some of the customer application needs which need to be accommodated:
52#  8. Some customers will want to support large CPU count systems with
53#     good scaling.  Thus, we'll need to accommodate a number of
54#     Ingress Queues and MSI-X Vectors to allow up to some number of CPUs
55#     to be involved per port and per application function.  For example,
56#     in the case where all ports and application functions will be
57#     managed via a single Unified PF and we want to accommodate scaling up
58#     to 8 CPUs, we would want:
59#
60#         4 ports *
61#         3 application functions (NIC, FCoE, iSCSI) per port *
62#         8 Ingress Queue/MSI-X Vectors per application function
63#
64#     for a total of 96 Ingress Queues and MSI-X Vectors on the Unified PF.
65#     (Plus a few for Firmware Event Queues, etc.)
66#
67#  9. Some customers will want to use T4's PCI-E SR-IOV Capability to allow
68#     Virtual Machines to directly access T4 functionality via SR-IOV
69#     Virtual Functions and "PCI Device Passthrough" -- this is especially
70#     true for the NIC application functionality.  (Note that there is
71#     currently no ability to use the TOE, FCoE, iSCSI, etc. via Virtual
72#     Functions so this is in fact solely limited to NIC.)

418# MPS features a 196608 bytes ingress buffer that is used for ingress buffering
419# for packets from the wire as well as the loopback path of the L2 switch. The
420# folling params control how the buffer memory is distributed and the L2 flow
421# control settings:
422#
423# bg_mem:	%-age of mem to use for port/buffer group
424# lpbk_mem:	%-age of port/bg mem to use for loopback
425# hwm:		high watermark; bytes available when starting to send pause
426#		frames (in units of 0.1 MTU)
427# lwm:		low watermark; bytes remaining when sending 'unpause' frame
428#		(in inuits of 0.1 MTU)
429# dwm:		minimum delta between high and low watermark (in units of 100
430#		Bytes)
