The function ena_com_ind_tbl_convert_from_device() has an overflow
bug as explained below. Either way, this function is not needed at
all since we don't retrieve the indirection table from the device
at any point which means that this conversion is not needed.
The bug:
The for loop iterates over all io_sq_queues, when passing the actual
number of used queues the io_sq_queues[i].idx equals 0 since they are
uninitialized which results in the following code to be executed till
the end of the loop:
dev_idx_to_host_tbl[0] = i;
This results dev_idx_to_host_tbl[0] in being equal to
ENA_TOTAL_NUM_QUEUES - 1.

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.
