Govindarajulu Varadarajan 3256d29fc7 enic: initialize enic->rfs_h.lock in enic_probe 
lockdep spotted that we are using rfs_h.lock in enic_get_rxnfc() without
initializing. rfs_h.lock is initialized in enic_open(). But ethtool_ops
can be called when interface is down.

Move enic_rfs_flw_tbl_init to enic_probe.

INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

README 

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.
See Documentation/00-INDEX for a list of what is contained in each file.

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.
