Re: iSCSI: padding on intermediate sequences

["Robert D. Russell" <rdr@io.iol.unh.edu>]

Eddy:

I may not be understanding you correctly, but the
words in section 9.7.7 I believe mean that these data
segments should contain an integer number of 4 byte words
of data, not arbitrary "pad" bytes.  If the data segment
length is a multiple of 4 then there will be NO pad bytes.

There seems to be confusion over your use of "pad"
and the standard's use of "pad".  Would you please clarify?

Thanks,
Bob
