Subject: i40e: rename 'cmd' variables in ethtool interface

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.

Subject: i40e: fix clearing link masks in i40e_get_link_ksettings

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.

Subject: i40e: group autoneg PHY types together

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.

From 1eaae5198e0db1f523fa3432ded69247aa33bf20 Mon Sep 17 00:00:00 2001
From: Alan Brady <alan.brady@intel.com>
Date: Thu, 5 Oct 2017 14:53:41 -0700
Subject: i40e: convert i40e_phy_type_to_ethtool to new API

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.

Subject: i40e: convert i40e_get_settings_link_up to new API

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.

Subject: i40e: rename 'change' variable to 'autoneg_changed'

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.

Subject: i40e: convert i40e_set_link_ksettings to new API

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.

From 6c32e0d9fdd56a7af54512aff700e20d85563499 Mon Sep 17 00:00:00 2001
From: Alan Brady <alan.brady@intel.com>
Date: Mon, 9 Oct 2017 15:48:45 -0700
Subject: i40e: fix u64 division usage

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")
