Dear Alan,
I am not speaking about the 'Max Transfers' instead I am talking about
the MAX bottom most row. I did not understand how is max bandwidth
jumped to 187500 value.
Please see the row containing the following fields:
Bandwidth Bytes/Frame
(Usefull data)
Max 187500 187
Regards,
Mukund Jampala
