Hello everyone,
Recently I found that packets sent from vmxnet3 driver on guest have
MSS value set to very small size, some 10 bytes, some 25 bytes MSS.
The vmxnet3 NIC enables TSO. Could you let me know any possible reason

As I know we have a socket option SO_TCP_NODELAY to disable Nagle

https://elixir.bootlin.com/linux/v4.4.90/source/net/ipv4/tcp.c#L2401 .
However, I do not know where the source code the Nagle Algorithm is
implemented in ke
