Well, there is ng_tcpmss  but I see that it only works for IPv4
It may however be relatively easy to add code to allow it to work for 
IPV6.

there is also the code in ports net/tcpmss which also is only IPV4,but 
in addition
relies on DIVERT which is currently IPV4 only (I hope to change that).

I assume you don't include things like ppp links if you are talking 
about a server.

don't know about pf.  it MAY be able to help.

For what it is worth, I expect a lot of IPV6 stuff to get kicked into 
shape over the next few months :-)
