Hi!

The first patch is a small fix for flower offload, we need a whitelist
of supported matches, otherwise the unsupported ones will be ignored.

The second and the third patch are adding wait/polling to the probe path.
We had reports of driver failing probe because it couldn't find the 
control process (NSP) on the card.  Turns out the NSP will only announce
its existence after it's fully initialized.  Until now we assumed it 
will be reachable, just not processing commands (hence we wait for
a NOOP command to execute successfully).

v2:
 - fix a bad merge which resulted in a build warning and retest.

  nfp: wait for board state before talking to the NSP
  nfp: wait for the NSP resource to appear on boot

Pieter Jansen van Vuuren (1):
  nfp: add whitelist of supported flow dissector
