[cifs-protocol] [MS-SMB2] sign for 3.3.5.15.11 FSCTL_QUERY_NETWORK_INTERFACE_INFO

[Jones Syue 薛懷宗]

Hello Dochelp,

Per multichannel test[1] and wireshark packet[2], windows client would sign 
request/response pair of SMB2 Ioctl FSCTL_QUERY_NETWORK_INTERFACE_INFO.
Both [MS-SMB2] 3.3.5.15.11 and 3.2.5.14.11 looks like not mention about it,
please help clarify:
1. sign for SMB2 Ioctl FSCTL_QUERY_NETWORK_INTERFACE_INFO is expected?
2. if expected, could we update [MS-SMB2] to document this behavior? a bit
   like what Tree Connect[3] and Session Setup[4] did.

Thank you :)

If Connection.Dialect is "3.1.1" and Session.IsAnonymous and 
Session.IsGuest are set to FALSE and the request is not signed or not 
encrypted, then the server MUST disconnect the connection.

field, and Session.IsAnonymous is FALSE, the server MUST sign the final 
session setup response before sending it to the client, as follows:
