The driver currently blindly deletes its cache of RSS cotexts and
ntuple filters when the ethtool channel count is changing. It also
deletes the ntuple filters cache when the default indirection table
is changing.
The core will not allow ethtool channels to drop below any that
have been configured as ntuple destinations since this commit from 2022:
47f3ecf4763d ("ethtool: Fail number of channels change when it conflicts with rxnfc")
So there is absolutely no need to delete the ntuple filters and
RSS contexts when changing ethtool channels.
It is also unnecessary to delete ntuple filters when the default
RSS indirection table is changing.
Remove bnxt_clear_usr_fltrs() and bnxt_clear_rss_ctxis() from the
ethtool ops and change them to static functions.
This bug will cause confusion to the end user and causes failure when
running the rss_ctx.py selftest.

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.
