    tcp: Ignore TCP_NOPUSH socketopt by default
    
    For ill optimized programs which misuses this sockopt will cause
    unpredicted length of network stalling, if the total sending size
    is not TCP sending segment size aligned.
    
    sysctl node net.inet.tcp.disable_nopush controls whether TCP_NOPUSH
    will take effect or not
    
    I am not going to fight agaist the stupid programs in the wild.

    This is actually _not_ a bug on our side.
