    net-timestamp: only report sw timestamp if reporting bit is set · c199105d
    Willem de Bruijn authored
    The timestamping API has separate bits for generating and reporting
    timestamps. A software timestamp should only be reported for a packet
    when the packet has the relevant generation flag (SKBTX_..) set
    and the socket has reporting bit SOF_TIMESTAMPING_SOFTWARE set.
    
    The second check was accidentally removed. Reinstitute the original
    behavior.
    
    Tested:
      Without this patch, Documentation/networking/txtimestamp reports
      timestamps regardless of whether SOF_TIMESTAMPING_SOFTWARE is set.
      After the patch, it only reports them when the flag is set.
    
    Fixes: f24b9be5 ("net-timestamp: extend SCM_TIMESTAMPING ancillary data struct")
