cdc_ncm: Implement the 32-bit version of NCM Transfer Block
[ Upstream commit 0fa81b30 ] The NCM specification defines two formats of transfer blocks: with 16-bit fields (NTB-16) and with 32-bit fields (NTB-32). Currently only NTB-16 is implemented. This patch adds the support of NTB-32. The motivation behind this is that some devices such as E5785 or E5885 from the current generation of Huawei LTE routers do not support NTB-16. The previous generations of Huawei devices are also use NTB-32 by default. Also this patch enables NTB-32 by default for Huawei devices. During the 2019 ValdikSS made five attempts to contact Huawei to add the NTB-16 support to their router firmware, but they were unsuccessful.
