Without window scaling the maximum TCP window size is limited to 64K.
Many of the other settings will not matter because of this limit. This
basically means the total number of bytes "in flight" on the network
without window scaling is set to this maximum by the protocol. e.g.
window size is a 16 bit unsigned number in the TCP header.
