commitc646d10ddaupstream. After the blamed patch, all RX traffic gets hashed to CPU 0 because the hashing indirection table set up in: enetc_pf_probe -> enetc_alloc_si_resources -> enetc_configure_si -> enetc_setup_default_rss_table is overwritten later in: enetc_pf_probe -> enetc_init_port_rss_memory which zero-initializes the entire port RSS table in order to avoid ECC errors. The trouble really is that enetc_init_port_rss_memory really neads enetc_alloc_si_resources to be called, because it depends upon enetc_alloc_cbdr and enetc_setup_cbdr. But that whole enetc_configure_si thing could have been better thought out, it has nothing to do in a function called "alloc_si_resources", especially since its counterpart, "free_si_resources", does nothing to unwind the configuration of the SI. The point is, we need to pull out enetc_configure_si out of enetc_alloc_resources, and move it after enetc_init_port_rss_memory. This allows us to set up the default RSS indirection table after initializing the memory.

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.
