    [DCCP]: Revert patch which disables bidirectional mode
    
    This reverts an earlier patch which disabled bidirectional mode, meaning 
that
    a listening (passive) socket was not allowed to write to the other (active)
    end of the connection.
    
    This mode had been disabled when there were problems with CCID3, but it
    imposes a constraint on socket programming and thus hinders deployment.
    
    A change is included to ignore RX feedback received by the TX CCID3 module.
    
    Many thanks to Andre Noll for pointing out this issue.
