     @azonenberg @unlambda I'm debugging this in simulation (Amaranth makes it real easy to save stuff to a snoop file)

     @whitequark @unlambda Wow.

     Honestly I didn't even know it was possible to get FCSes in Wireshark because NICs normally drop frames with bad FCS so they don't show up in the capture.

     Any time I've needed to troubleshoot FCS stuff I've slapped scope probes down on the *MII bus or the SFP diff pair or used my SFP/RJ45 mid-span tap fixtures then decoded in ngscopeclient

     @whitequark @unlambda (yes i implemented a pcapng parser in systemverilog, call me crazy but i'd rather do that than use python)

     @azonenberg @unlambda honestly, just using SystemVerilog at all is a sign of masochism so extreme, I cannot condone it (and I'm into some pretty wild kinks)

     @whitequark @unlambda Ah, OK.

     I have the opposite (replay pcapng as frames over axi4-stream) for switch fabric debugging but currently no pcap sink
