Merge branch 'nfp-TC-block-fixes-app-fallback-and-dev_alloc'

Jakub Kicinski says:

====================
nfp: TC block fixes, app fallback and dev_alloc()

This series has three parts.  First of all John and I fix some
fallout from the TC block conversion.  John also fixes sleeping
in the neigh notifier.

Secondly I reorganise the nfp_app table to make it easier to
deal with excluding apps which have unmet Kconfig dependencies.

Last but not least after the fixes which went into -net some time
ago I refactor the page allocation, add a ethtool counter for
failed allocations and clean the ethtool stat code while at it.
====================
