in which case the calculation in the RMPP code is off.
I agree the text might be missing an example or two for clarification.
Anyway, we probably can use the IB Analyzer as the ultimate
interpretation test. Note that there are IB implementations that uses
the first segment payload length as the source of packet length and
count on it to represent the correct DATA length.
We can take your interpretation to discussion in the IBTA MGTWG for
further discussion.
Is the effort for fixing it big?
It's not a big deal to change it. If the common interpretation is to only
include the partial data size, I will change it.
I think the common interpretation is that the paylen n the first segment should present
the size of the "valid" data only.
