Subject: [PATCH net-next 1/6] ibmvnic: Generalize TX pool structure

Remove some unused fields in the structure and include values
describing the individual buffer size and number of buffers in
a TX pool. This allows us to use these fields for TX pool buffer
accounting as opposed to using hard coded values. Finally, split
TSO buffers out and provide an additional TX pool array for TSO.
