Add support for doing just this, in a per-device configurable way. > While at it, update NCM subdrivers, disabling this functionality in all of > them, except in huawei_cdc_ncm where it is enabled instead. > We aren't making any distinction between different Huawei NCM devices, > based on what the vendor driver does.
