[Intel-wired-lan] [next PATCH S45 01/10] i40evf: remove unnecessary error checking against i40evf_up_complete

[Bimmy Pujari]

Function i40evf_up_complete() always returns success. Changed this to a
void type and removed the code that checks the return status and prints
an error message.

[Intel-wired-lan] [next PATCH S45 02/10] i40e: Limit TX descriptor count in cases where frag size is greater than 16K

[Bimmy Pujari]

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

The i40e driver was incorrectly assuming that we would always be pulling
no more than 1 descriptor from each fragment.  It is in fact possible for
us to end up with the case where 2 descriptors worth of data may be pulled
when a frame is larger than one of the pieces generated when aligning the
payload to either 4K or pieces smaller than 16K.

To adjust for this we just need to make certain to test all the way to the
end of the fragments as it is possible for us to span 2 descriptors in the
block before us so we need to guarantee that even the last 6 descriptors
have enough data to fill a full frame.

        This is hard to reproduce.  Patch submitted to customer for
        testing.  Best effort would be to try testing TSO, if possible
        TSO with iSCSI to verify nothing there is broken.

[Intel-wired-lan] [next PATCH S45 04/10] i40e: Remove 100 Mbps SGMII support for X722

[Bimmy Pujari]

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

This patch fixes the problem where driver shows 100 Mbps as a supported speed, 
and allows it to be configured for advertising on X722 devices. This patch 
fixes the problem by not setting the 100 Mbps SGMII flag for X722 devices. 

Without this patch, the user incorrectly thinks that 100 Mbps is supported 
and hence might try to advertise it on X722 devices when it is actually not 
a supported speed.

[Intel-wired-lan] [next PATCH S45 05/10] i40e: fix deleting mac filters

[Bimmy Pujari]

From: Alan Brady <alan.brady@intel.com>

There exists a bug in which deleting a mac filter does not actually
occur.  The driver reports that the filter has been deleted with no
error.  The problem occurs because the wrong cmd_flag is passed to the
firmware when deleting the filter.  The firmware reports an error back
to the driver but it is expressly ignored.

This fixes the bug by using the correct flag when deleting a filter.
Without this patch, deleted filters remain in firmware and function as
if they had not been deleted.

Add ENCAP_CSUM offload negotiation flag. Currently VF assumes checksum
offload for encapsulated packets is supported by default. Going forward,
this feature needs to be negotiated with PF before advertising to the
stack. Hence, we need a flag to control it.
This is in regards to prepping up for VF base mode functionality support.

[Intel-wired-lan] [next PATCH S45 07/10] i40e: cleanup ATR auto_disable_flags use

[Bimmy Pujari]

From: Jacob Keller <jacob.e.keller@intel.com>

Some locations that disable ATR accidentally used the "full" disable by
disabling the flag in the standard flags field. This incorrectly forces
ATR off permanently instead of temporarily disabling it. In addition,
some code locations accidentally set the ATR flag enabled when they only
meant to clear the auto_disable_flags. This results in ignoring the
user's ethtool private flag settings.

Additionally, when disabling ATR via ethtool, we did not perform a flush
of the FD table. This results in the previously assigned ATR rules still
functioning which was not expected.

Cleanup all these areas so that automatic disable uses only the
auto_disable_flag. Fix the flush code so that we can trigger a flush
even when we've disabled ATR and SB support, as otherwise the flush
doesn't work. Fix ethtool setting to actually request a flush. Fix
NETIF_F_NTUPLE flag to only clear the auto_disable setting and not
enable the full feature.

[Intel-wired-lan] [next PATCH S45 08/10] i40e: check conflicting ntuple/sideband rules when re-enabling ATR

[Bimmy Pujari]

From: Jacob Keller <jacob.e.keller@intel.com>

In i40e_fdir_check_and_reenable(), the driver performs some checks to
determine whether it is safe to re-enable FD Sideband and FD ATR
support. The current check will only determine if there is available
space in the flow director table. However, this ignores the fact that
ATR should be disabled when there are TCP/IPv4 sideband rules in effect.
Add the missing check, and update the info message printed when
I40E_DEBUG_FD is enabled.

[Intel-wired-lan] [next PATCH S45 08/10] i40e: check conflicting ntuple/sideband rules when re-enabling ATR

> 
> In i40e_fdir_check_and_reenable(), the driver performs some checks to
> determine whether it is safe to re-enable FD Sideband and FD ATR support.
> The current check will only determine if there is available space in the flow
> director table. However, this ignores the fact that ATR should be disabled
> when there are TCP/IPv4 sideband rules in effect.
> Add the missing check, and update the info message printed when
> I40E_DEBUG_FD is enabled.

[Intel-wired-lan] [next PATCH S45 04/10] i40e: Remove 100 Mbps SGMII support for X722

> This patch fixes the problem where driver shows 100 Mbps as a supported
> speed, and allows it to be configured for advertising on X722 devices. This
> patch fixes the problem by not setting the 100 Mbps SGMII flag for X722
> devices.
> 
> Without this patch, the user incorrectly thinks that 100 Mbps is supported
> and hence might try to advertise it on X722 devices when it is actually not a
> supported speed.

Driver no longer reports 100Base/T nor allows advertise to be set to 100Base/T
