Michael Brown e191298a1d [tcp] Calculate correct MSS from peer address iPXE currently advertises a fixed MSS of 1460, which is correct only for IPv4 over Ethernet. For IPv6 over Ethernet, the value should be 1440 (allowing for the larger IPv6 header). For non-Ethernet link layers, the value should reflect the MTU of the underlying network device. Use tcpip_mtu() to calculate the transport-layer MTU associated with the peer address, and calculate the MSS to allow for an optionless TCP header as per RFC 6691. As a side benefit, we can now fail a connection immediately with a meaningful error message if we have no route to the destination address. Reported-by: Anton D.
