Constant Socket Receive Buffer

[Tharindu Rukshan Bamunuarachchi]

Dear All,

How can I maintain constant/minimum socket receive buffer.

I have used setsockopt() with SO_RCVBUF value for  256bytes

But according to tcpdump window size is changing after connection is
estabilished.

Can It be possible to set socket receive buffer value less than
sysctl_tcp_rmem's minimum value.

Do I have to disable tcp_window_scaling


Thankx
Regards
Tharindu
