I have found the answer of this question in *TCP*. In the file net/ipv4/tcp_output.c there is a function called "tcp_mtu_to_mss" where calculates the PMTU, taking into account IP options. Now, I would like to know where *UDP* does this operation. I would be very glad of receiving any answer. Thanks. Enrique.
