The indirection table has the indices of the Rx queues. When we store it
during set indirection operation, we convert the indices to our internal
representation of the indices.
Our internal representation of the indices is: even indices for Tx and
uneven indices for Rx, where every Tx/Rx pair are in a consecutive order
starting from 0. For example if the driver has 3 queues (3 for Tx and 3
for Rx) then the indices are as follows:
0 1 2 3 4 5
Tx Rx Tx Rx Tx Rx
The BUG:
The issue is that when we satisfy a get request for the indirection
table, we don't convert the indices back to the original representation.
The FIX:
Simply apply the inverse function for the indices of the indirection
table after we set it.

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.
