Since we only allocate VIs for the number of TXQs we actually need, we cannot naively use "channel * TXQ_TYPES + txq" for the TXQ number, as this has gaps (when efx->tx_queues_per_channel < EFX_TXQ_TYPES) and thus overruns the driver's VI allocations, causing the firmware to reject the MC_CMD_INIT_TXQ based on INSTANCE. Thus, we distinguish INSTANCE (stored in tx_queue->queue) from LABEL (tx_queue->label); the former is allocated starting from 0 in efx_set_channels(), while the latter is simply the txq type (index in channel->tx_queue array). To simplify things, rather than changing tx_queues_per_channel after setting up TXQs, make Siena always probe its HIGHPRI queues at start of day, rather than deferring it until tc mqprio enables them.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
