Aurora IP 8B10B problem with TVALID

I am getting unexpected SOF(AXI_OP_TVALID) signal down as shown in the
figure (find the fig in attachments). I have taken  example design as a
reference. In the dsign, I fixed frame size (X"07"). But in Rx, SOF is
getting down near  EOF( as in fig).I want to receive complete frame data
beat.In the waveform,SOF means VALID, EOF means TLAST.I am trying to get
complete data from SOF to EOF as TX side.Can anybody give solution for
the problem?
