+Below module is included in this package:<br>
+- NetworkCommon
+- UsbCdcEcm
+- UsbCdcNcm
+- UsbRndis
+
+## [NetworkCommon]
+Provides a LAN driver based on UEFI specification(UNDI). It supports USB communication class subclass devices and USB Rndis devices, depending on the UsbEthernetProtocol.
+
+## Required Components
+- NetworkPkg
+
+## [UsbCdcEcm]
+This driver provides a communication interface for USB Ethernet devices that follows the ECM protocol. The driver installs UsbEthernetProtocol with ECM functions which are consumed by the NetworkCommon driver.
+
+The driver is compatible with the following USB class codes:
+|Class Code|SubClass Code|Protocol Code|
+|:--------:|:-----------:|:-----------:|
+|0x02|0x06|0x00|
+
+## Required Components
+- NetworkCommon
+- MdeModulePkg(USB bus driver)
+
+## [UsbCdcNcm]
+This driver provides a communication interface for USB Ethernet devices that follows the NCM protocol. The driver installs UsbEthernetProtocol with NCM functions which are consumed by the NetworkCommon driver.
+
+The driver is compatible with the following USB class codes:
+|Class Code|SubClass Code|Protocol Code|
+|:--------:|:-----------:|:-----------:|
+|0x02|0x0D|0x00|
+
+## Required Components

+ Retrieves a Unicode string that is the user readable name of the controller

+
+ This function retrieves the user readable name of the controller specified by

+ driver specified by This has a user readable name in the language specified by
+ Language, then a pointer to the controller name is returned in ControllerName,

+ managing the controller specified by ControllerHandle and ChildHandle,
+ then EFI_UNSUPPORTED is returned. If the driver specified by This does not
+ support the language specified by Language, then EFI_UNSUPPORTED is returned.
+
+ @param[in] This A pointer to the EFI_COMPONENT_NAME2_PROTOCOL or
+ EFI_COMPONENT_NAME_PROTOCOL instance.
+ @param[in] Controller The handle of a controller that the driver
+ specified by This is managing. This handle
+ specifies the controller whose name is to be
+ returned.
+ @param[in] ChildHandle The handle of the child controller to retrieve
+ the name of. This is an optional parameter that
+ may be NULL. It will be NULL for device
+ drivers. It will also be NULL for a bus drivers
+ that wish to retrieve the name of the bus
+ controller. It will not be NULL for a bus
+ driver that wishes to retrieve the name of a
+ child controller.
+ @param[in] Language A pointer to a Null-terminated ASCII string
+ array indicating the language. This is the
+ language of the driver name that the caller is
+ requesting, and it must match one of the
+ languages specified in SupportedLanguages. The
+ number of languages supported by a driver is up
+ to the driver writer. Language is specified in
+ RFC 4646 or ISO 639-2 language code format.
+ @param[out] ControllerName A pointer to the Unicode string to return.
+ This Unicode string is the name of the
+ controller specified by ControllerHandle and
+ ChildHandle in the language specified by
+ Language from the point of view of the driver
+ specified by This.
+
+ @retval EFI_SUCCESS The Unicode string for the user readable name in
+ the language specified by Language for the
+ driver specified by This was returned in
+ DriverName.
+ @retval EFI_INVALID_PARAMETER ControllerHandle is not a valid EFI_HANDLE.
+ @retval EFI_INVALID_PARAMETER ChildHandle is not NULL and it is not a valid
+ EFI_HANDLE.
+ @retval EFI_INVALID_PARAMETER Language is NULL.
+ @retval EFI_INVALID_PARAMETER ControllerName is NULL.
+ @retval EFI_UNSUPPORTED The driver specified by This is not currently

**CAUTION: The e-mail below is from an external source. Please exercise caution before opening attachments, clicking links, or following guidance.**
You probably don't need to add it in _this_ patch series, but since
you're adding a new package you'll need to add an entry to Maintainers.txt.

Hi All, are you sure a new package is really needed for the USB network devices that suppose should be located under MdeModulePkg/Bus/Usb for example MdeModulePkg/Bus/Usb/UsbNetwork?
We still can add an entry in Maintainers.txt for MdeModulePkg/Bus/Usb/UsbNetwork.

Yes, you can add me as a reviewer.
A couple more comments on the patches: why are ECM and NCM disabled by
default?
I've tested on my Juno R2 system and it appears rate limiting is
required, so should it be enabled by default?
Given this is adding a new top-level package, I'd like to see a
review/feedback from the TianoCore Stewards.

I would personally love to understand why this is being pushed as a
top level package in edk2 when "supposedly" edk2-platforms/Features is
the more correct approach here (as discussed with Sean, Nate a few
months back).
Or is that hellscape only reserved for me? :v

Hi Pedro/Abner,
UsbNetworkPkg provide the RNDIS/ECM/NCM device support that are implement form USB specification(we have other USB network device's driver to upstream).
It is not specific USB device. The driver could work on any platform. So, we create UsbNetworkPkg same as NetworkPkg in edk2 repo.
Currently, we have some Fixed PCDs in UsbNetworkPkg.dec. Can add it to MdeModulePkg.dec?
Which one is better for upstream from below rules?
#1: edk2-platforms/Features/UsbNetworkPkg
#2: edk2/MdeModulePkg/Bus/Usb/UsbNetwork
#3: edk2/UsbNetworkPkg
Thanks,
Richard

Hi Richard and Pedro,
Understand that is the standard USB communication class device, that is why I think put it under MdeModulePkg/Bus/Usb/UsbNetwork makes more sense because it is similar to the USB mass storage or HID classes.
USB RNDIS driver and EDKII USB Ethernet protocol are on top of USB devices that akin to BLOCK IO protocol to USB MSD, which I think those two can be located under MdeModulePkg/Bus/Usb/UsbNetwork as well because those are only used by USB CDC devices.
That is no problem to add those fixed PCDs and other definitions such as protocol definitions in MdeModulePkg.dec if UsbNetwork is part of MdeModulePkg.
Thanks

Hi Richard,
I was wondering if you'd seen my questions about ECM and NCM, and rate
limiting?

Hi Rebecca,
ECM and NCM will be enable when move the UsbNetworkPkg to MdeModulePkg\Bus\Usb\UsbNetwork.
About rate limiting. We have test it X86 system. It will be slow to PXE boot.
Do you think this PCD should be enabled by default?
Thanks,
Richard
