Hi,

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.

Currently we are setting these bits to 0 indicating no capabilities on our device and still we observe that Host (Linux kernel host cdc driver) has been sending requests specific to these capabilities.

Hi,

please test the patch I've attached to kernel.org's bugzilla.
