Hi all,
I am reading "header_payload_demux" module, I have some questions about it.
1, in "header_payload_demux_impl.cc" line 235, seems need update nread's value
        nread += trigger_offset;
I think without this update, the first header will check failed, if input data not include complete "d_header_len" ofdm symbols

2, why in "case STATE_HEADER_RX_FAIL:" line 218, need consume one input item?

3, does the control message's handler function can disturb "general_work"(like a soft interrupt)?, or these handler only run before/after "general_work".
