Lines Matching full:mss

132  * The default maximum segment size (MSS) to be used for new TCP connections
135  * RFC879 derives the default MSS from the largest datagram size hosts are
140  * For IPv4 the MSS is 576 - sizeof(struct tcpiphdr)
141  * For IPv6 the MSS is IPV6_MMTU - sizeof(struct ip6_hdr) - sizeof(struct tcphdr)
149  * Limit the lowest MSS we accept for path MTU discovery and the TCP SYN MSS
150  * option.  Allowing low values of MSS can consume significant resources and
152  * Connections requesting lower MSS values will be rounded up to this value
