8149b1500d blk: Rename if_type to uclass_id
Use the word 'uclass' instead of 'if_type' to complete the conversion.

71346a8486 net: enetc: force the RGMII MAC speed/duplex instead of using in-band signaling
The RGMII spec supports optional in-band status reporting for the speed
and duplex negotiated on the copper side, and the ENETC driver enables
this feature by default.

However, this does not work when the PHY does not implement the in-band
reporting, or when there is a MAC-to-MAC connection described using a
fixed-link. In that case, it would be better to disable the feature in
the ENETC MAC and always force the speed and duplex to the values that
were negotiated and retrieved over MDIO once the autoneg is finished.
Since this works always, we just do it unconditionally and drop the
in-band code.

Note that because we need to wait for the autoneg to complete, we need
to move enetc_setup_mac_iface() after phy_startup() returns, and then
pass the phydev pointer all the way to enetc_init_rgmii().

The same considerations have led to a similar Linux driver patch as well:

71a2d1e7b8 drivers: net: Add Felix DSA switch driver
This driver is used for the Ethernet switch integrated into LS1028A NXP.
Felix on LS1028A has 4 front panel ports and two internal ports, I/O
to/from the switch is done through an ENETC Ethernet interface.
The 4 front panel ports are available as Ethernet interfaces and can be
used with the typical network commands like tftp.

9c2aee1b19 drivers: net: fsl_enetc: Pass on primary MAC address to Linux
Passes on the primary address used by u-boot to Linux. The code does a DT
fix-up for ENETC PFs and sets the primary MAC address in IERB. The address
in IERB is restored on ENETC PCI functions at FLR.

e4aafd5c20 drivers: net: apply serdes configuration for ENETC Ethernet interfaces
Ethernet interfaces using serial protocols go through the serdes block
integrated in the SoC.  This is accessed over dedicated internal MDIOs
which are part of the Ethernet PCI functions.  Set up serdes at _start,
along with other protocol specific port/MAC configuration.
MDIO code is shared with enetc_mdio, read/write functions are exported
from fsl_enetc_mdio for this reason.

1d99534bef drivers: net: add NXP ENETC MDIO driver
Adds a driver for the MDIO interface currently integrated in LS1028A SoC.
This MDIO interface is shared by multiple ethernet interfaces and is
presented as a stand-alone PCI function on the SoC ECAM.
Ethernet has a functional dependency on MDIO, for simplicity there is a
single config option for both.
