Modifying default MSS of internet library


Hi All,
I am trying to chnage default MSS of wip internet library with the parameter WIP_NET_OPT_TCP_MIN_MSS using wip_netSetOpts api provided by wip library

The wip internet library usermanual states the default value of MSS is 536 bytes. and can be modified by the the above mentoined api.

But unfortunately it is not changing.

I am using firmware 7.54.2

Please reply soon its urgent as this is going to resolve my issue of transmitting TCP buffer of size more than 1024 bytes.
