+ support
+
+The 100BASE-FX and 100BASE-LX support assumes a PHY is present; this
+is probably an incorrect assumption. In any case, sfp_parse_support()
+will fail such a module. Let's stop pretending we support these
+modules.

+Subject: [PATCH 646/660] net: sfp: add module start/stop upstream
+ notifications
+
+When dealing with some copper modules, we can't positively know the
+module capabilities are until we have probed the PHY. Without the full
+capabilities, we may end up failing a module that we could otherwise
+drive with a restricted set of capabilities.
+
+An example of this would be a module with a NBASE-T PHY plugged into
+a host that supports phy interface modes 2500BASE-X and SGMII. The
+PHY supports 10GBASE-R, 5000BASE-X, 2500BASE-X, SGMII interface modes,
+which means a subset of the capabilities are compatible with the host.
+
+However, reading the module EEPROM leads us to believe that the module
+only supports ethtool link mode 10GBASE-T, which is incompatible with
+the host - and thus results in the module being rejected.
+
+This patch adds an extra notification which are triggered after the
+SFP module's PHY probe, and a corresponding notification just before
+the PHY is removed.

+Move phy_start() and phy_stop() into the module_start and module_stop
+notifications in phylink, rather than having them in the SFP code.
+This gives phylink responsibility for controlling the PHY, rather
+than having SFP start and stop the PHY state machine.

+Subject: [PATCH 651/660] net: phylink: split link_an_mode configured and
+ current settings
+
+Split link_an_mode between the configured setting and the current
+operating setting.  This is an important distinction to make when we
+need to configure PHY mode for a plugged SFP+ module that does not
+use in-band signalling.

+Subject: [PATCH 653/660] net: phylink: delay MAC configuration for copper SFP
+ modules
+
+Knowing whether we need to delay the MAC configuration because a module
+may have a PHY is useful to phylink to allow NBASE-T modules to work on
+systems supporting no more than 2.5G speeds.
+
+This commit allows us to delay such configuration until after the PHY
+has been probed by recording the parsed capabilities, and if the module
+may have a PHY, doing no more until the module_start() notification is
+called.  At that point, we either have a PHY, or we don't.
+
+We move the PHY-based setup a little later, and use the PHYs support
+capabilities rather than the EEPROM parsed capabilities to determine
+whether we can support the PHY.

+Subject: [PATCH 654/660] net: phylink: make Broadcom BCM84881 based SFPs work
+
+The Broadcom BCM84881 does not appear to send the SGMII control word
+when operating in SGMII mode, which causes network adapters to fail
+to link with the PHY, or decide to operate at fixed 1G speed, even if
+the PHY negotiated 100M.
+
+Work around this by detecting the Broadcom BCM84881 and switch to phy
+mode rather than inband mode.

+Subject: [PATCH 656/660] net: sfp: add support for Clause 45 PHYs
+
+Some SFP+ modules have a Clause 45 PHY onboard, which is accessible via
+the normal I2C address.  Detect 10G BASE-T PHYs which may have an
+accessible PHY and probe for it.
