On DPAA2 platforms that lack a TCAM (like LS1088A), masking of
flow steering keys is not supported. Until now we didn't offer
flow steering capabilities at all on these platforms.

Introduce a limited support for flow steering, where we only
allow ethtool rules that share a common key (i.e. have the same
header fields). If a rule with a new composition key is wanted,
the user must first manually delete all previous rules.

First patch fixes a minor bug, the next two cleanup and prepare
the code and the last one introduces the actual FS support.

Series applied, thanks Ioana.
