[Intel-wired-lan] [next PATCH S61 00/10] i40e/i40evf updates

[Bimmy Pujari]

Alexander Duyck updated code to better handle incrementing page count, 
added code to fix use after free in Rx cleanup path, cleans-up 
process_skb_fields function, drops FCoE code from core driver files 
and drops FCoE code that always evaluates to false or 0.

Bimmy Pujari removed delays which were no loger needed.

Carolyn Wyborny fixed code for queue timing delays.

Harshitha Ramamurthy added code to fix configuration of RSS table with
DCB.

Henry Tieman added support for 25G in ethtool.

Robert Konklewski added code to fix race conditions in VF reset.

[Intel-wired-lan] [next PATCH S61 01/10] i40e/i40evf: Update code to better handle incrementing page count

[Bimmy Pujari]

From: Alexander Duyck <alexander.h.duyck@intel.com>

Update the driver code so that we do bulk updates of the page reference
count instead of just incrementing it by one reference at a time.  The
advantage to doing this is that we cut down on atomic operations and
this in turn should give us a slight improvement in cycles per packet.
In addition if we eventually move this over to using build_skb the gains
will be more noticeable.

I also found and fixed a store forwarding stall from where we were
assigning "*new_buff = *old_buff".  By breaking it up into individual
copies we can avoid this and as a result the performance is slightly
improved.

[Intel-wired-lan] [next PATCH S61 02/10] i40e: fix configuration of RSS table with DCB

[Bimmy Pujari]

From: Harshitha Ramamurthy <harshitha.ramamurthy@intel.com>

There exists a bug in the driver where the calculation of the
RSS size was not taking into account the number of traffic classes
enabled. This patch factors in the traffic classes both in
the initial configuration of the table as well as reconfiguration.

        The "Fixes" commit ID will need to be updated before this is pushed
        upstream.  Ideally this patch can be dropped if the patch that
        introduced the bug has not yet made it upstream, and this fix can
        be taken care of there.

[Intel-wired-lan] [next PATCH S61 04/10] i40e: Fixed race conditions in VF reset

[Bimmy Pujari]

From: Robert Konklewski <robertx.konklewski@intel.com>

First, this patch eliminates IOMMU DMAR Faults caused by VF hardware.
This is done by enabling VF hardware only after VSI resources are
freed. Otherwise, hardware could DMA into memory that is (or just has
been) being freed.

Then, the VF driver is activated only after VSI resources have been
reallocated. That's because the VF driver can request resources
immediately after it's activated. So they need to be ready at that
point.

The second race condition happens when the OS initiates a VF reset,
and then before it's finished modifies VF's settings by changing its
MAC, VLAN ID, bandwidth allocation, anti-spoof checking, etc. These
functions needed to be blocked while VF is undergoing reset. Otherwise,
they could operate on data structures that had just been freed or not
yet fully initialized.

Testing Hints:
 Create 8 VMs with 8 VFs each (the more the better).
 Set MTU=9000 for all VFs on Guest OS boot (this triggers VF reset).
 Reboot all VMs at once, wait until they are up, repeat.

[Intel-wired-lan] [next PATCH S61 05/10] i40e: Add support for 25G in ethtool

[Bimmy Pujari]

From: Henry Tieman <henry.w.tieman@intel.com>

Implemented functions for the updated get and set commands
in ethtool: ETHTOOL_GLINKSETTING and ETHTOOL_SLINKSETTINGS.
These new commands will replace the existing functionality
of ETHTOOL_GSET and ETHTOOL_SSET, which have been deprecated.

Macros for 25G support were added to the include files at the
same time as the new ethtool commands. So, 25G support has
been implemented in the new functions.

Signed-off-by: Henry Tieman <henry.w.tieman@intel.com>
Change-ID: I3824ed616cf92bc8bdce3e976277a0cf94d0cd35
---
Testing Hints: The kernel macros required by this patch are
available in Linux kernels after 4.7. Also, the 25G macros have
been back ported into RHEL7.3. This functionality was added in
ethtool version 4.5.

[Intel-wired-lan] [next PATCH S61 08/10] i40e/i40evf: Clean-up process_skb_fields

[Bimmy Pujari]

From: Alexander Duyck <alexander.h.duyck@intel.com>

This is a minor clean-up to make the i40e/i40evf process_skb_fields
function look a little more like what we have in igb.  The Rx checksum
function called out a need for skb->protocol but I can't see where it
actually needs it.  I am assuming this is something that was likely
refactored out some time ago as the Rx checksum code has gone through a few
rewrites.

        checksums correctly.

[Intel-wired-lan] [next PATCH S61 09/10] i40e: Drop FCoE code from core driver files

[Bimmy Pujari]

From: Alexander Duyck <alexander.h.duyck@intel.com>

Looking over the code for FCoE it looks like the Rx path has been broken at
least since the last major Rx refactor almost a year ago.  It seems like
FCoE isn't supported for any of the Fortville/Fortpark hardware so there
isn't much point in carrying the code around, especially if it is broken
and untested.

This patch cleans the FCoE code out of the CORE files and permanently sets
the build flags so that the FCoE bits are stripped out of the shared code.

It was generated using 2 passes.  First with unifdef, and then manually
going through and eliminating any extra #ifdef cruft such as an extra

Testing Hints:
        Driver should function the same as before.  The only real change
        is that we stripped out code that was either ifdef'ed out or
        code that was unused since FCoE would never be enabled.

[Intel-wired-lan] [next PATCH S61 10/10] i40e: Drop FCoE code that always evaluates to false or 0

[Bimmy Pujari]

From: Alexander Duyck <alexander.h.duyck@intel.com>

Since FCoE isn't supported by the i40e products there isn't much point in
carrying around code that will always evaluate to false. This patch goes
through and strips out the code in several spots so that we don't go around
carrying variables and/or code that is always going to evaluate to false or
0.

[Intel-wired-lan] [next PATCH S61 04/10] i40e: Fixed race conditions in VF reset

> First, this patch eliminates IOMMU DMAR Faults caused by VF hardware.
> This is done by enabling VF hardware only after VSI resources are freed.
> Otherwise, hardware could DMA into memory that is (or just has
> been) being freed.
> 
> Then, the VF driver is activated only after VSI resources have been
> reallocated. That's because the VF driver can request resources immediately
> after it's activated. So they need to be ready at that point.
> 
> The second race condition happens when the OS initiates a VF reset, and
> then before it's finished modifies VF's settings by changing its MAC, VLAN ID,
> bandwidth allocation, anti-spoof checking, etc. These functions needed to be
> blocked while VF is undergoing reset. Otherwise, they could operate on data
> structures that had just been freed or not yet fully initialized.
