[Intel-wired-lan] [PATCH v3 00/14 net-next] i40e: refactor ethtool interface

[Alan Brady]

This series brings i40e ethtool interface back into the modern era by
converting references to the old ethtool API to the new API.

This conversion allows us to provide much better support for new 25G and
10G PHY types.

This also includes a patch which adds new function to ethtool;
ethtool_intersect_link_masks.  i40e uses this function is used to take
what is supported by the PHY type and intersect it with what is
supported by the NVM, giving us what is truly supported.

v2: Removed extra new line.  Fixed comment split.  Removed
i40e_intersect_link_masks and added ethtool_intersect_link_masks to
net/core/ethtool.c.  Removed '.' from title of commit 09/13

v3: Fixed typo in "13/13 i40e: convert i40e_set_link_ksettings to new
API"; "unsuported" to "unsupported".  Extracted the addition of
ethtool_intersect_link_masks into its own patch.

Alan Brady (13):
  i40e: rename 'cmd' variables in ethtool interface
  i40e: remove ifdef SPEED_25000
  i40e: add function header for i40e_get_rxfh

  i40e: fix i40e_phy_type_to_ethtool function header
  i40e: fix comment typo
  i40e: fix whitespace issues in i40e_ethtool.c
  i40e: group autoneg PHY types together
  ethtool: add ethtool_intersect_link_masks
  i40e: convert i40e_phy_type_to_ethtool to new API
  i40e: convert i40e_get_settings_link_up to new API

[Intel-wired-lan] [PATCH v3 01/14 net-next] i40e: rename 'cmd' variables in ethtool interface

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 04/14 net-next] i40e: fix clearing link masks in i40e_get_link_ksettings

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 08/14 net-next] i40e: group autoneg PHY types together

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 10/14 net-next] ethtool: add ethtool_intersect_link_masks

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 11/14 net-next] i40e: convert i40e_phy_type_to_ethtool to new API

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 12/14 net-next] i40e: convert i40e_get_settings_link_up to new API

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 13/14 net-next] i40e: rename 'change' variable to 'autoneg_changed'

[Alan Brady]

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.

[Intel-wired-lan] [PATCH v3 14/14 net-next] i40e: convert i40e_set_link_ksettings to new API

[Alan Brady]

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.
