Intel 82574L

[Pavo]

I have figure out how to make this NIC use the native kexts without any modification of the NIC firmware as suggested in other threads.

Add the following to Clover config:

<key>ForceKextsToLoad</key>
<array>
<string>\System\Library\Extensions\IONetworkingFamily.kext\Contents\PlugIns\Intel82574L.kext</string>
</array>

And the following to the KextsToPatch section:

<key>KextsToPatch</key>
<array>
<dict>
<key>Comment</key>
<string>Remove IOPCISecondaryMatch</string>
<key>Disabled</key>
<false/>
<key>Find</key>
<data>
SU9QQ0lTZWNvbmRhcnlNYXRjaA==
</data>
<key>InfoPlistPatch</key>
<true/>
<key>Name</key>
<string>Intel82574L</string>
<key>Replace</key>
<data>
SURPTk9Ud2FudHRvbG9hZHRoaQ==
</data>
</dict>
</array>

Then either add this to your DSDT or make a SSDT:

Device (_SB.PCI0.PEX0.ETH0)
    {
        Name (_ADR, Zero)  // _ADR: Address
        Method (_DSM, 4, NotSerialized)  // _DSM: Device-Specific Method
        {
            If (LEqual (Arg2, Zero))
            {
                Return (Buffer (One)
                {
                     0x03                                          
                })
            }

            Store (Package (0x14)
                {
                    "AAPL,slot-name",
                    "Built In",
                    "model",
                    Buffer (0x0D)
                    {
                        "Intel 82574L"
                    },

                    "built-in",
                    Buffer (One)
                    {
                         0x00                                          
                    },

                    "device-id",
                    Buffer (0x04)
                    {
                         0xF6, 0x10, 0x00, 0x00                        
                    },

                    "vendor-id",
                    Buffer (0x04)
                    {
                         0x86, 0x80, 0x00, 0x00                        
                    },

                    "subsystem-vendor-id",
                    Buffer (0x04)
                    {
                         0x00, 0x00, 0x00, 0x00                        
                    },

                    "subsystem-id",
                    Buffer (0x04)
                    {
                         0x00, 0x00, 0x00, 0x00                        
                    },

                    "device_type",
                    Buffer (0x09)
                    {
                        "ethernet"
                    },

                    "location",
                    Buffer (0x02)
                    {
                        "1"
                    },

                    "name",
                    Buffer (0x09)
                    {
                        "ethernet"
                    }
                }, Local0)
            DTGP (Arg0, Arg1, Arg2, Arg3, RefOf (Local0))
            Return (Local0)
        }
    }

This will use the native kext from macOS located in /System/Library/Extensions/IONetworkingFamily.kext/Contents/Plugins/Intel82574L.kext

how do we go about making a ssdt for this?
