In order to program the correct Steering Tag during an IRQ affinity change, we need to free/re-allocate the RX completion ring during queue_restart. If TPH is enabled, call FW to free the Rx completion ring and clear the ring entries in queue_stop(). Re-allocate it in queue_start() if TPH is enabled. Note that TPH mode is not enabled in this patch and will be enabled later in the patch series. While modifying bnxt_queue_start(), remove the unnecessary zeroing of rxr->rx_next_cons. It gets overwritten by the clone in bnxt_queue_start(). Remove the rx_reset counter increment since restart is not reset. Add comment to clarify that the ring allocations in queue_start should never fail.

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 reStructuredText 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.
