In this case, can you assign me one more value for FC with SOF? The reason is that our module can send out two type of packets: One with SOF, one without SOF. I will add one dissector in wireshark to support FC with SOF (If it doesn't exist). Thanks, Kahou On Thu, Jul 16, 2009 at 2:30 AM, Guy Ha

Yes, the packet starts with the R_CTL field. Basically my company is making a fibre channel module which can generate fibre channel packet on the transmit side and we have functionality to capture the packet on the receive side, this is done on the hardware level. On the software level, we can que
