The PCIe specification, rev 3.0, section 2.2.8.1, contains the following
implementation note:
Virtual Wire Mapping for INTx Interrupts From ARI Devices
The implied Device Number for an ARI Device is 0. When ARI-aware
software (including BIOS and operating system) enables ARI Forwarding in
the Downstream Port immediately above an ARI Device in order to access
its Extended Functions, software must comprehend that the Downstream Port
will use Device Number 0 for the virtual wire mappings of INTx interrupts
coming from all Functions of the ARI Device. If non-ARI-aware software
attempts to determine the virtual wire mappings for Extended Functions,
it can come up with incorrect mappings by examining the traditional
Device Number field and finding it to be non-0.
We account for this in pci_swizzle_interrupt_pin(), but it looks like we
miss it here, looking for a _PRT entry with a slot matching the ARI device
slot number. This can cause errors like:
pcieport 0000:80:03.0: can't derive routing for PCI INT B
sfc 0000:82:01.1: PCI INT B: no GSI
pci_dev.irq is then invalid, resulting in errors for drivers that attempt
to enable INTx on the device. Fix by using slot 0 for ARI enabled devices.

The same area used for ioremap() is used for the MTRR area.
Convert the driver from using the x86 specific MTRR code to
the architecture agnostic arch_phys_wc_add(). arch_phys_wc_add()
will avoid MTRR if write-combining is available, in order to
take advantage of that also ensure the ioremap'd area is requested
as write-combining.
There are a few motivations for this:
a) Take advantage of PAT when available
b) Help bury MTRR code away, MTRR is architecture specific and on
x86 its replaced by PAT
c) Help with the goal of eventually using _PAGE_CACHE_UC over
_PAGE_CACHE_UC_MINUS on x86 on ioremap_nocache() (see commit
de33c442e titled "x86 PAT: fix performance drop for glx,
use UC minus for ioremap(), ioremap_nocache() and
pci_mmap_page_range()")
The conversion done is expressed by the following Coccinelle
SmPL patch, it additionally required manual intervention to
address all the #ifdery and removal of redundant things which
arch_phys_wc_add() already addresses such as verbose message
about when MTRR fails and doing nothing when we didn't get

====================
net/mlx5: ConnectX-4 100G Ethernet driver
This patchset extends the mlx5_core driver to support Ethernet
functionality. The Ethernet functionality in the mlx5 driver is
integrated into the core driver and not as separated driver. The
IB functionality remains in the mlx5_ib driver as before.
This functionality will enable the Ethernet capability of Mellanox's new
famility of cards - ConnectX-4. Due to the fact that backword
compatability is being kept, existing Connect-IB cards that are using
this driver are fully working with the modified driver, and no issues
with current deployments should be seen.
Like the ConnectX-3 cards, ConnectX-4 is a VPI (Virtual Port Interface -
every port can be configured as Infiniband or Ethernet) card.
Unlike previous generations, the ConnectX-4 has a separate PCI function
per port.
The current code has a limitation that Infiniband and Ethernet port types
are mutually exclusive. When the driver is compiled with Ethernet
support, the Infiniband functionality is disabled and vice versa. To
control that we added the CONFIG_MLX5_CORE_EN config directive
which is 'n' by default, but can be changed by the user.
This limitation is short-lived and would be addressed soon.
As part of this patchset, mlx5_ifc.h was heavily modified [1]. This file
is now generated automatically from the device specification document.
Since this patch is too big for the mail server, it might be missing in
the mailing list, but could be pulled from an external git repository [2].
irq name selection is done at driver initialization and doesn't contain the
interface name as part of the irq name.
irq_balancer will still work thanks to an improvement introduced by Neil Horman
[3] to use sysfs instead of /proc/interrupts.
Patchset was applied on top of commit ed2dfd9 ("tcp/dccp: warn user for
preferred ip_local_port_range")
[1] - Patch 4/11 ("net/mlx5_core: HW data structs/types definitions preparation for mlx5 ehternet driver")

Amir
Changes from V4:
- Removed Patch 3/12: net/mlx5_core: Add EQ renaming mechanism
- Patch 12/12: net/mlx5: Extend mlx5_core to support ConnectX-4 Ethernet functionality
- irq name is created on driver initialization, therefore it won't contain
the network interface name in it. This won't effect irq_balancer thanks to
patches introduced by Neil Horman to use sysfs instead of /proc/interrupts.

- Return value directly - no need for err.
Changes from V2:
- Improved changelogs and cover-letter
- Added CONFIG_MLX5_EN to disable/enable the Ethernet functionality
- Moved en.h and wq.[ch] into the patch with data-path related code

This is the Ethernet part of the driver for the Mellanox ConnectX(R)-4
Single/Dual-Port Adapter supporting 100Gb/s with VPI. The driver
extends the existing mlx5 driver with Ethernet functionality.
This patch contains the driver entry points but does not include
transmit and receive (see the previous patch in the series) routines.
It also adds the option MLX5_CORE_EN to Kconfig to enable/disable the
Ethernet functionality. Currently, Kconfig is programmed to make
Ethernet and Infiniband functionality mutally exclusive.
Also changed MLX5_INFINIBAND to be depandant on MLX5_CORE instead of
selecting it, since MLX5_CORE could be selected without MLX5_INFINIBAND
being selected.

This patch contains the resource handling files:
- flow_table.c: This file contains the code to handle the low level API
to configure hardware flow table. It is separated from
the flow_table_en.c, because it will be used in the
future by Raw Ethernet QP in mlx5_ib too.
- en_flow_table.[ch]: Ethernet flow steering handling. The flow table
object contain a mapping between flow specs and TIRs.
This mechanism will be used also to configure e-switch
in the future, when SR-IOV support will be added.
- transobj.[ch] - Low level functions to create/modify/destroy the
transport objects: RQ/SQ/TIR/TIS
- vport.[ch] - Handle attributes of a virtual port (vPort) in the
embedded switch. Currently this switch is a passthrough, until SR-IOV

en_[rt]x.c contains the data path related code specific to tx or rx.
en_txrx.c contains data path code which is common for both the rx and
tx, this is mainly napi related code.
Below are the objects that are being used by the hardware and the driver
in the data path:
Channel - one channel per IRQ. Every channel object contains:
RQ - describes the rx queue
TIR - One TIR (Transport Interface Receive) object per flow type. TIR
contains attributes for a type of rx flow (e.g IPv4, IPv6 etc).
A flow is defined in the Flow Table.
Currently TIR describes the RSS hash parameters if exists and LRO
attributes.
SQ - describes the a tx queue. There is one SQ (Send Queue) per
TC (traffic class).
TIS - There is one TIS (Transport Interface Send) per TC. It
describes the TC and may later be extended to describe more
transport properties.
Both RQ and SQ inherit from the object WQ (work queue). This common code
to describe the layout of CQE's WQE's in memory is in the files wq.[cj]
For every channel there is one NAPI context that is used for RX and
for TX.
Driver is using netdev_alloc_skb() to allocate skb's.

Intel Wired LAN Driver Updates 2015-05-28
This series contains updates to ethtool, ixgbe, i40e and i40evf.
John adds helper routines for ethtool to pass VF to rx_flow_spec. Since
the ring_cookie is 64 bits wide which is much larger than what could be
used for actual queue index values, provide helper routines to pack a VF
index into the cookie. Then John provides a ixgbe patch to allow flow
director to use the entire queue space.
Neerav provides a i40e patch to collect XOFF Rx stats, where it was not
being collected before.
Anjali provides ATR support for tunneled packets, as well as stats to
count tunnel ATR hits. Cleaned up PF struct members which are
unnecessary, since we can use the stat index macro directly. Cleaned
up flow director ATR/SB messages to a higher debug level since they
are not useful unless silicon validation is happening.
Greg provides a patch to disable offline diagnostics if VFs are enabled
since ethtool offline diagnostic tests are not designed (out of scope)
to disable VF functions for testing and re-enable afterward. Also cleans
up TODO comment that is no longer needed.
Vasu provides a fix an FCoE EOF case where i40e_fcoe_ctxt_eof() maybe
called before i40e_fcoe_eof_is_supported() is called.
Jesse adds skb->xmit_more support for i40evf. Then provides a performance
enhancement for i40evf by inlining some functions which provides a 15%
gain in small packet performance. Also cleans up the use of time_stamp
since it is no longer used to determine if there is a tx_hang and was
a part of a previous tx_hang design which is no longer used.
