[PATCH net-next 0/6] ibmvnic: Update TX pool and TX routines
This patch restructures the TX pool data structure and provides a separate TX pool array for TSO transmissions. This is already used in some way due to our unique DMA situation, namely that we cannot use single DMA mappings for packet data. Previously, both buffer arrays used the same pool entry. This restructuring allows for some additional cleanup in the driver code, especially in some places in the device transmit routine. In addition, it allows us to more easily track the consumer and producer indexes of a particular pool. This has been further improved by better tracking of in-use buffers to prevent possible data corruption in case an invalid buffer entry is used.
