The field tcp.window_size_scalefactor can have the following values:

• -2: The 3-way-handshake was seen, but the client and/or the server did not support window scaling, so it is not used
• -1: Part of the 3-way handshake was not seen and it could not be determined if window-scaling is used
• 0: The host supports window-scaling, but will not use window-scaling itself (multiply by 2^0=1)
• n (n>0): The host supports window-scaling, but will not use window-scaling itself (multiply by 2^n)
