Re: how much "Desired Data Transfer Length" in R2T

["Subrahmanya Sastry K.V" <skotra@npd.hcltech.com>]

Hi Nitin,

It seems that the case you mentioned (send R2T, get two Data PDUs)
can happen when the DataPDULength value of the target is greater than the
DataPDULength value of the initiator because
the minimum of the two DataPDULengths is selected.
In that case, the target may get more than one DataPDU in response to one R2T.
The target knows the end of data when the F bit is set in the DataPDU that it
receives.

Any more comments?
