Ok, that adds the following at level 3 (with adjacent lines for context):

Code:

Mar 12 11:47:02 192.168.60.5 ipxe: iSCSI 0xe06e4 start 28:00:00:00:00:00:00:00:01:00:00:00:00:00:00:00 in 0x200
Mar 12 11:47:02 192.168.60.5 ipxe: SCSI 0xe0b04 tag 18ae0006 READ 28:00:00:00:00:00:00:00:01:00:00:00:00:00:00:00
Mar 12 11:47:02 192.168.60.5 ipxe: iSCSI 0xe06e4 received PDU opcode 0x25 len 0x200

...which I think is coming from here: https://github.com/ipxe/ipxe/blob/7b976d...si.c#L438, but I note it returns 0?

I'm struggling to follow the call graph from the int13 hooks into the iSCSI and down to the SCSI layer, TBH, which makes figuring out where that flag is coming from rather difficult!
