Dirk Mueller ab94c6b021 Enable liberal TCP connection tracking for SNAT namespaces
This can avoid connections rarely hanging due to tcp window
scaling not correctly being observed by the TCP connection
tracking. this seems to happen when retransmits are occurring
occassionally.
Setting this parameter turns off validating the window scaling
checks for the purpose of matching whether a packet matches
an existing connection tracked flow, which avoids the SNAT
namespace from interfering and letting the connection peers
recover the connection via retransmits/Selective ACKs instead
of the SNAT terminating one side of the connection and letting
it stall permanently.
