If a TCP connection is using AH or ESP does the mss option sent
during the SYN account for the AH/ESP headers also ?

Assume the MTU of the link is 1500. Normally the mss (without
any options) is 1460 (20 bytes of TCP and 20 bytes of IP
header). If the connection uses AH/ESP does the sending
side decrease the mss further ? Curious to know what
the other implementation do out there. Currently i am assuming
it decreases the mss further if AH/ESP is present.
