68e7f45e11 sfc: Use generic MDIO functions and definitions
Make use of the newly-added generic MDIO clause 45 support and remove
redundant definitions.

Add an 'efx_' prefix to the remaining driver-specific MDIO functions
and remove arguments which are redundant with efx->mdio.prtad.

d2d2c37314 sfc: Add support for QT2025C PHY
This is a new PHY supporting SFP+ modules, used in the SFN4112F
reference design.  It is similar to the QT2022C2 and shares much of
its support code.

ab37735870 sfc: Use model numbers for PHY type names
Some of the PHY type names are overly generic.  Change them to include
the model numbers of the PHYs they represent.

Correct the model number reference at the top of xfp_phy.c.

766ca0fa6b sfc: Rework MAC, PHY and board event handling
From: Steve Hodgson <shodgson@solarflare.com>

MAC, PHY and board events may be separately enabled and signalled.
Our current arrangement of chaining the polling functions can result
in events being missed.  Change them to be more independent.

04cc8cacb0 sfc: Implement auto-negotiation
Add infrastructure for auto-negotiation of speed, duplex and flow
control.

When using 10Xpress, auto-negotiate flow control.  While we're
at it, clean up the code to warn when partner is not 10GBASE-T
capable.

177dfcd80f sfc: Add support for sub-10G speeds
The SFC4000 has a separate MAC for use at sub-10G speeds.  Introduce
an efx_mac_operations structure with implementations for the two MACs.
Switch between the MACs as necessary.

PHY settings are independent of the MAC, so add get_settings() and
set_settings() to efx_phy_operations.  Also add macs field to indicate
which MACs the PHY is connected to.

3e133c44d2 sfc: Use lm87 and lm90 drivers for board temperature/power monitoring
Add board monitoring to periodic work whenever link is down.
For SFE4001, report when a fault has caused the PHY to turn off.
For SFE4002, switch XFP PHY into low-power state in case of a fault.

ef08af03ef sfc: Remove workaround for old firmware bug
There was a bug in XAUI synchronisation in early 10Xpress firmware
versions.  This is fixed in released firmware and we do not need to

f8b87c1701 sfc: Make PHY flash mode a device attribute, not a module parameter
This allows updating PHY firmware for one interface without removing
all other interfaces handled by the driver.

Replace tx_disabled flags and 10Xpress status enumeration with flags in
enum efx_phy_mode.

Prevent an interface from being brought up while in PHY flash mode.
