====================
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.

v5: Fix bisectability mistake in the first patch. Removed
    TSO-specific data in a later patch when it is no longer used.

v4: Fix error in 7th patch that causes an oops by using
    the older fixed value for number of buffers instead
    of the respective field in the tx pool data structure

v3: Forgot to update TX pool cleaning function to handle new data
    structures. Included 7th patch for that.

v2: Fix typo in 3/6 commit subject line
