Before Linux 5.3, i.e. before Linux kernel commit 8f7baad7f035 ("tcp: Add snd_wnd to TCP_INFO"), the sending window (\fIsnd_wnd\fR field) is not available. -If the sending window cannot be queried, it will always be announced as a fixed -value to guest or target namespace (14 600 bytes, suggested by RFC 6928), and -segments received by guest or target namespace will be acknowledged as soon as -the corresponding payload is enqueued to the corresponding socket. The normal -behaviour is to acknowledge segments only as the remote peer acknowledges the -corresponding payload, in order to reflect the congestion control dynamic back -to the sender. This might affect throughput of TCP connections. +If the sending window cannot be queried, it will always be announced as the +current sending buffer size to guest or target namespace.
