    tcp: Remove TCPCT · 1a2c6181
    Christoph Paasch authored
    TCPCT uses option-number 253, reserved for experimental use and should
    not be used in production environments.
    Further, TCPCT does not fully implement RFC 6013.
    
    As a nice side-effect, removing TCPCT increases TCP's performance for
    very short flows:
    
    Doing an apache-benchmark with -c 100 -n 100000, sending HTTP-requests
    for files of 1KB size.
    
    before this patch:
    	average (among 7 runs) of 20845.5 Requests/Second
    after:
    	average (among 7 runs) of 21403.6 Requests/Second
