Device driver gets access to rxfh_dev, while rxfh is just a local copy of user space params. We need to check what RSS context ID driver assigned in rxfh_dev, not rxfh. Using rxfh leads to trying to store all contexts at index 0xffffffff. From the user perspective it leads to "driver chose duplicate ID" warnings when second context is added and inability to access any contexts even tho they were successfully created - xa_load() for the actual context ID will return NULL, and syscall will return -ENOENT. Looks like a rebasing mistake, since rxfh_dev was added relatively recently by commitfb6e30a725("net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool ops").

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.
