Merge branch 'nfp-vf-rate-limit-support'

Simon Horman says:

====================
*nfp: VF rate limit support

this short series adds VF rate limiting to the NFP driver.

The first patch, as suggested by Jakub Kicinski, adds a helper
to check that ndo_set_vf_rate() rate parameters are sane.
It also provides a place for further parameter checking to live,
if needed in future.

The second patch adds VF rate limit support to the NFP driver.
It addresses several comments made on v1, including removing
the parameter check that is now provided by the helper added
in the first patch.
