[net-next 00/15][pull request] 40GbE Intel Wired LAN Driver Updates 2017-10-17

[Jeff Kirsher]

This series contains updates to i40e and ethtool.

Alan provides most of the changes in this series which are mainly fixes
and cleanups.  Renamed the ethtool "cmd" variable to "ks", since the new
ethtool API passes us ksettings structs instead of command structs.
Cleaned up an ifdef that was not accomplishing anything.  Added function
header comments to provide better documentation.  Fixed two issues in
i40e_get_link_ksettings(), by calling
ethtool_link_ksettings_zero_link_mode() to ensure the advertising and
link masks are cleared before we start setting bits.  Cleaned up and fixed
code comments which were incorrect.  Separated the setting of autoneg in
i40e_phy_types_to_ethtool() into its own conditional to clarify what PHYs
support and advertise autoneg, and makes it easier to add new PHY types in
the future.  Added ethtool functionality to intersect two link masks
together to find the common ground between them.  Overhauled i40e to
ensure that the new ethtool API macros are being used, instead of the
old ones.  Fixed the usage of unsigned 64-bit division which is not
supported on all architectures.

Sudheer adds support for 25G Active Optical Cables (AOC) and Active Copper
Cables (ACC) PHY types.

The following are changes since commit 8a5f2166a6288ee4b5a393f1ebc8cfb26b0510f0:
  net: export netdev_txq_to_tc to allow sch_mqprio to compile as module

[net-next 01/15] i40e: rename 'cmd' variables in ethtool interface

[Jeff Kirsher]

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

After the switch to the new ethtool API, ethtool passes us
ethtool_ksettings structs instead of ethtool_command structs, however we
were still referring to them as 'cmd' variables.  This renames them to
'ks' variables which makes the code easier to understand.

[net-next 04/15] i40e: fix clearing link masks in i40e_get_link_ksettings

[Jeff Kirsher]

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

This fixes two issues in i40e_get_link_ksettings.  It adds calls to
ethtool_link_ksettings_zero_link_mode to make sure advertising and
supported link masks are cleared before we start setting bits in them.

This also replaces some funky bit manipulations with a much nicer call
to ethtool_link_ksettings_del_link_mode when removing link modes.

[net-next 05/15] i40e: fix i40e_phy_type_to_ethtool function header

[Jeff Kirsher]

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

The function header erroneously listed 'phy_types' as a parameter.  The
correct parameter is 'pf'.

[net-next 08/15] i40e: group autoneg PHY types together

[Jeff Kirsher]

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

This separates the setting of autoneg in i40e_phy_types_to_ethtool into
its own conditional.  Doing this adds clarity as what PHYs
support/advertise autoneg and makes it easier to add new PHY types in
the future.

This also fixes an issue on devices with CRT_RETIMER where advertising
autoneg was being set, but supported autoneg was not.

[net-next 10/15] ethtool: add ethtool_intersect_link_masks

[Jeff Kirsher]

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

This function provides a way to intersect two link masks together to
find the common ground between them.  For example in i40e, the driver
first generates link masks for what is supported by the PHY type.  The
driver then gets the link masks for what the NVM supports.  The
resulting intersection between them yields what can truly be supported.

[net-next 11/15] i40e: convert i40e_phy_type_to_ethtool to new API

[Jeff Kirsher]

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

We are still largely using the old ethtool API macros.  This is
problematic because eventually they will be removed and they only
support 32 bits of PHY types.

This overhauls i40e_phy_type_to_ethtool to use only the new API.  Doing
this also allows us to provide much better support for newer 25G and 10G
PHY types which is included here as well.

The remaining usages of the old ethtool API will be addressed in other
patches in the series.

[net-next 12/15] i40e: convert i40e_get_settings_link_up to new API

[Jeff Kirsher]

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

This removes references to old ethtool API macros and functions in
i40e_get_settings_link_up as part of the process of converting to the
new API.  The new API also allows us to provide more explicit support
for new 25G and 10G PHY types so some of the PHY types have been
adjusted where necessary as well.

[net-next 13/15] i40e: rename 'change' variable to 'autoneg_changed'

[Jeff Kirsher]

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

This variable isn't actually very descriptive and makes the code a bit
confusing as to what it is being used for.  This patch enhances the
variable with the longer name, 'autoneg_changed', which makes it clear
we are concerned with autoneg changing in this context.

[net-next 14/15] i40e: convert i40e_set_link_ksettings to new API

[Jeff Kirsher]

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

This finishes off the conversion to the new ethtool API by removing the
old macros being used in i40e_set_link_ksettings and replacing them with
shiny new ones.

This conversion also allows us to provide link speed support for new 25G
and 10G macros which is included here as well.

[net-next 15/15] i40e: fix u64 division usage

[Jeff Kirsher]

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

Commit 52eb1ff93e98 ("i40e: Add support setting TC max bandwidth rates")
and commit 1ea6f21ae530 ("i40e: Refactor VF BW rate limiting") add some
needed functionality for TC bandwidth rate limiting.  Unfortunately they
introduce several usages of unsigned 64-bit division which needs to be
handled special by the kernel to support all architectures.

Fixes: 52eb1ff93e98 ("i40e: Add support setting TC max bandwidth
rates")
Fixes: 1ea6f21ae530 ("i40e: Refactor VF BW rate limiting")
