Add support for Broadcom Ethernet

[unitedastronomer]

edit: I have rewritten it on the next comment.

List is based on supported by FakePCIIID kext on Catalina.

Hi, I don't recommend getting the kext in AppleLife because the website will delete attachments as they get older. Grab from this mirror, or use the CatalinaBCM5701 in OCLP's repo instead.

Big Sur to Sequoia

minKernel: 20.0.0

Option 1: Grab the mirror of the AppleLife kext in this repo. No need spoofs, I already expanded the supported device-id the Info.plist.

The more technical one: Take the kext from OCLP, as they are most likely maintained.

• CatalinaBCM5701Ethernet.kext

Device Properties:

Key*	Value	Type
IOName	pci14e4,16b4	String
compatible	pci14e4,16b4	String

Use IOName instead of device-id,so it would show the correct model in Hackintool, spoofing one of the IOName match from it's plist just works fine.

Kernel
Add:

	minKernel
CatalinaBCM5701Ethernet	20.0.0

Patch:

Identifier*	Find	Replace	minKernel	Count	Comment
com.apple.iokit.CatalinaBCM5701Ethernet	E8CA9EFF FF668983 00050000	B8B41600 00668983 00050000	20.0.0	1	Broadcom BCM577XX Patch

Cosmetic (SysReport):

Identifier*	Find	Replace	minKernel	Count	Comment
com.apple.iokit.CatalinaBCM5701Ethernet	35373736 35	35373738 35	20.0.0	0	SysReport 57765 -> 57785 (Cosmetic)

3 5 3 7 3 7 3 6 3 5 -> 3 5 3 7 3 7 3 8 3 5

Catalina and older

Option 1: Add FakePCIID.kext maxKernel: 19.99.99 , that's all.

Option 2:

Device Properties: Same as above
Patch: Enable "BCM57785" patch in the sample.plist
Cosmetic: Same as above but the identifier is com.apple.iokit.AppleBCM5701Ethernet, maxKernel: 19.99.9

I cannot use the same "BCM57785" patch present on sample.plist on injected ethernet.kext (on macOS >=11) because masking for Kernel -> Patch don't work using OC's config.plist. I had to replace the whole series of hex.
