RE: [iSCSI:] Logout request -- reason? Correction

Luben,

I don't see where you got that impression. The BHS layout shows bytes 1 through 3 as opcode specific fields. The kinds of opcode specific fields will be different depending upon opcode.

Subject: [iSCSI:] Logout request -- reason? Correction


Let me correct this:

I was under the impression that byte 1 in BHS
is a flags byte -- i.e. bit values.
 
I now see that the reason code is moved exactly there,
in the Logout request PDU.
 
Could anyone please explain the logic behind this?

At the same time byte 2 and 3 are reserved to 0.

Why don't we:

1)  Move the reason code to byte 2. This will
    make it _consistent_ with the response byte
    in Logout Response.

2)  Make the value start at 0x80, as to hide
    the ugliness of F = 1, and the fact that
    we are trying to fit a numerical value (!)
    and a bit value (!) in the same octet.

Comments?
