Referring to patch with commit ID (*e10dcb1b6ba714243ad5a35a11b91cc14103a9a9*).
This is a spec violation for CDC NCM class driver. Driver clearly says the significance of network capabilities. (snapshot below)
However, with the mentioned patch these values are disrespected and commands specific to these capabilities are sent from the host regardless of device' capabilities to handle them.
Right. So for your device, the correct behavior would be to do nothing, wouldn't it? The packets would be delivered and the host needs to filter and discard unrequested packets.
