3.16.7-ckt1 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Haiyang Zhang <[email protected]> commit 942396b01989d54977120f3625e5ba31afe7a75c upstream. total_data_buflen is used by netvsc_send() to decide if a packet can be put into send buffer. It should also include the size of RNDIS message before the Ethernet frame. Otherwise, a messge with total size bigger than send_section_size may be copied into the send buffer, and cause data corruption.
