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

README
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
