The wiki page for TCP::mss is pretty bare but unfortunately it appears to only be able to return the MSS, not set it which is a shame.

 

 

I understand your POV but I'd rather reduce the maximum packet payload by 11% than try to 'fix' someone else's multinational and administratively segregated network and security infrastructure again and again. If MTU was that important we'd all be using Jumbo Frames.
