Hi, We are facing the issue with TCP connection buffer size. TCP session is up. By default the rx buffer window size is 64k.Traffic flow= is fine. When the buffer size is increased while connection is up, rx buff= er window size is updated automatically with the new value. But if we decrease the buffer size below the default value i.e. 64k, window= size is not getting updated. To get it updated, we need to prune the conne= ction and setup with the new value(which is lesser than the default window = size). Is this a expected behavior in FreeBSD IP stack. Currently we are using Fre= eBSD v7.2.
