Hi Team,
I have a question in Zero Window Probe in TCP.
If the client sends Zero Window, according to RFC spec is it mandatory for the Linux TCP stack to send Zero Window Probe.
In my stack I am not getting Zero Window Probe instead I am getting Keep Alive.
I have attached my wireshark traces. Can you please confirm if this is the expected behavior from TCP stack.

Thanks & Regards
Kiruthika
