iSCSI: Byte padding requirement question

["Lee, WanHuiHendra" <WanHui_Lee@adaptec.com>]

Julian,

In the length field description (section 2.2.3 Length):
"... The length field accounts for proper iSCSI PDU content; whatever
padding is required to reach a 4 byte boundary in the TCP stream is implied
by the protocol but not accounted for in the length field."

Is this a side effect requirement due to the added "framing using marker at
fixed interval" mechanism ?

If yes, since framing is a negotiated feature, would it make sense to make
the byte padding only a requirement if framing is enabled ?

If this is not due to the framing feature, could you let us know why it is a
requirement (I did not see it in previous drafts) ?


Thanks,
Wan-Hui
