Use reserve bits

Dear All,

I would like to use the packet reserved bits : in signal pct_hdr_0 and or pct_hdr_1 to put information on the data packet received.
In FPGA I see how I could do, but in software I have to modificate the protocol and field of meta data to get the information
have you got an idea?



I have forced the pct_hdr_0 and pct_hdr_1 signals on the fpga to 0. I see that the timestamp is incremented by 32 with each LMS_RecvStream function call (& rx_streams [i_dev] [i], buffers_id0 [i], bufersize, & rx_metadata, 1000 );
buffersize = 8192

Why is it incrementing by 32?
