Subject: [PATCH 01/21] net: fman: memac: Add serdes support
This adds support for using a serdes which has to be configured. This is
primarly in preparation for phylink conversion, which will then change the
serdes mode dynamically.

Subject: [PATCH 02/21] net: fman: memac: Use lynx pcs driver
Although not stated in the datasheet, as far as I can tell PCS for mEMACs
is a "Lynx." By reusing the existing driver, we can remove the PCS
management code from the memac driver. This requires calling some PCS
functions manually which phylink would usually do for us, but we will let
it do that soon.
One problem is that we don't actually have a PCS for QSGMII. We pretend
that each mEMAC's MDIO bus has four QSGMII PCSs, but this is not the case.
Only the "base" mEMAC's MDIO bus has the four QSGMII PCSs. This is not an
issue yet, because we never get the PCS state. However, it will be once the
conversion to phylink is complete, since the links will appear to never
come up. To get around this, we allow specifying multiple PCSs in pcsphy.
This breaks backwards compatibility with old device trees, but only for
QSGMII. IMO this is the only reasonable way to figure out what the actual
QSGMII PCS is.
Additionally, we now also support a separate XFI PCS. This can allow the
SerDes driver to set different addresses for the SGMII and XFI PCSs so they
can be accessed at the same time.

Subject: [PATCH 07/21] net: remove explicit phylink_generic_validate()
references
Virtually all conventional network drivers are now converted to use
phylink_generic_validate() - only DSA drivers and fman_memac remain,
so lets remove the necessity for network drivers to explicitly set
this member, and default to phylink_generic_validate() when unset.
This is possible as .validate must currently be set.
Any remaining instances that have not been addressed by this patch can
be fixed up later.

Subject: [PATCH] net: dpaa2-mac: use Autoneg bit rather than an_enabled
The Autoneg bit in the advertising bitmap and state->an_enabled are
always identical. Thus, we will be removing state->an_enabled.
Use the Autoneg bit in the advertising bitmap to indicate whether
autonegotiation should be used, rather than using the an_enabled
member which will be going away. This means we use the same condition
as phylink_mii_c22_pcs_config().

Subject: [PATCH 10/21] net: phylink: support validated pause and autoneg in
fixed-link
In fixed-link setup phylink_parse_fixedlink() unconditionally sets
Pause, Asym_Pause and Autoneg bits to "supported" bitmap, while MAC may
not support these.
This leads to ethtool reporting:
> Supported pause frame use: Symmetric Receive-only
> Supports auto-negotiation: Yes
regardless of what is actually supported.
Instead of unconditionally set Pause, Asym_Pause and Autoneg it is
sensible to set them according to validated "supported" bitmap, i.e. the
result of phylink_validate().

Subject: [PATCH 13/21] net: phylink: fix ksettings_set() ethtool call
While testing a Fiberstore SFP-10G-T module (which uses 10GBASE-R with
rate adaption) in a Clearfog platform (which can't do that) it was
found that the PHYs advertisement was not limited according to the
hosts capabilities when using ethtool to change it.
Fix this by ensuring that we mask the advertisement with the computed
support mask as the very first thing we do.

Subject: [PATCH 15/21] net: phy: add helpers for comparing phy IDs
There are several places which open code comparing PHY IDs. Provide a
couple of helpers to assist with this, using a slightly simpler test
than the original:
- phy_id_compare() compares two arbitary PHY IDs and a mask of the
significant bits in the ID.
- phydev_id_compare() compares the bound phydev with the specified
PHY ID, using the bound driver's mask.

Subject: [PATCH 16/21] net: phylink: require supported_interfaces to be filled
We have been requiring the supported_interfaces bitmap to be filled in
by MAC drivers that have a mac_select_pcs() method. Now that all MAC
drivers fill in the supported_interfaces bitmap, it is time to enforce
this. We have already required supported_interfaces to be set in order
for optical SFPs to be configured in commit f81fa96d8a6c ("net: phylink:
use phy_interface_t bitmaps for optical modules").
Refuse phylink creation if supported_interfaces is empty, and remove
code to deal with cases where this mask is empty.

Subject: [PATCH 19/21] net: phylink: provide phylink_pcs_config() and
phylink_pcs_link_up()
Add two helper functions for calling PCS methods. phylink_pcs_config()
allows us to handle PCS configuration specifics in one location, rather
than the two call sites. phylink_pcs_link_up() gives us consistency.

Subject: [PATCH 20/21] net: phylink: actually fix ksettings_set() ethtool call
Raju Lakkaraju reported that the below commit caused a regression
with Lan743x drivers and a 2.5G SFP. Sadly, this is because the commit
was utterly wrong. Let's fix this properly by not moving the
linkmode_and(), but instead copying the link ksettings and then
modifying the advertising mask before passing the modified link
ksettings to phylib.

Subject: [PATCH 21/21] net: phylink: add PCS negotiation mode
PCS have to work out whether they should enable PCS negotiation by
looking at the "mode" and "interface" arguments, and the Autoneg bit
in the advertising mask.
This leads to some complex logic, so lets pull that out into phylink
and instead pass a "neg_mode" argument to the PCS configuration and
link up methods, instead of the "mode" argument.
In order to transition drivers, add a "neg_mode" flag to the phylink
PCS structure to PCS can indicate whether they want to be passed the
neg_mode or the old mode argument.

Convert fman_dtsec, xilinx_axienet and pcs-lynx to pass the neg_mode
into phylink_mii_c22_pcs_config(). Where appropriate, drivers are
updated to have neg_mode passed into their pcs_config() and
pcs_link_up() functions. For other drivers, we just hoist the call
to phylink_pcs_neg_mode() to their pcs_config() method out of
phylink_mii_c22_pcs_config().

Subject: [PATCH] net: pcs: lynxi: update PCS driver to use neg_mode
Update the Lynxi PCS driver to use neg_mode rather than the mode
argument. This ensures that the link_up() method will always program
the speed and duplex when negotiation is disabled.

Subject: [PATCH] net: pcs: xpcs: use Autoneg bit rather than an_enabled
The Autoneg bit in the advertising bitmap and state->an_enabled are
always identical. Thus, we will be removing state->an_enabled.
Use the Autoneg bit in the advertising bitmap to indicate whether
autonegotiation should be used, rather than using the an_enabled
member which will be going away.

Subject: [PATCH] net: pcs: xpcs: fix incorrect number of interfaces
In synopsys_xpcs_compat[], the DW_XPCS_2500BASEX entry was setting
the number of interfaces using the xpcs_2500basex_features array
rather than xpcs_2500basex_interfaces. This causes us to overflow
the array of interfaces. Fix this.
