There are no VF rings available during probe when the device is configured
using the Minimal-Static reservation strategy. In this case, the RSS
indirection table can only be initialized later, during bnxt_open_nic().
However, this was not happening because the rings will already have been
reserved via bnxt_init_dflt_ring_mode(), causing bnxt_need_reserve_rings()
to return false in bnxt_reserve_rings() and bypass the RSS table init.
Solve this by pushing the call to bnxt_set_dflt_rss_indir_tbl() into
__bnxt_reserve_rings(), which is common to both paths and is called
whenever ring configuration is changed. After doing this, the RSS table
init that must be called from bnxt_init_one() happens implicitly via
bnxt_set_default_rings(), necessitating doing the allocation earlier in
order to avoid a null pointer dereference.

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.
