[ Upstream commit 4844470d472d660c26149ad764da2406adb13423 ]
The device receives, stores and retrieves the hash function value as bits
and not as their enum value.
The bug:
* In ena_com_set_hash_function() we set
cmd.u.flow_hash_func.selected_func to the bit value of rss->hash_func.
(1 << rss->hash_func)
* In ena_com_get_hash_function() we retrieve the hash function and store
it's bit value in rss->hash_func. (Now the bit value of rss->hash_func
is stored in rss->hash_func instead of it's enum value)
The fix:
This commit fixes the issue by converting the retrieved hash function
values from the device to the matching enum value of the set bit using
ffs(). ffs() finds the first set bit's index in a word. Since the function
returns 1 for the LSB's index, we need to subtract 1 from the returned
value (note that BIT(0) is 1).
Fixes:

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.
