Summary: TCP_BUILD_MSS_OPTION doesn't consider netif->mtu,
causes slow network
Project: lwIP - A Lightweight TCP/IP stack

_______________________________________________________
Details:
TCP_BUILD_MSS_OPTION() only uses TCP_MSS value,
then if netif->mtu is smaller than TCP_MSS then there will be a lot of IP
fragmentation when packets will be going out = very slow network.
TCP_BUILD_MSS_OPTION should consider the route to dest_addr, and ask the netif
his mtu, and lower the tcp mss if required.
Thanks,
Amir Shalem
