Subject: [PATCH net-next 3/6] nfp: flower: increase scope of netdev checking functions
From: John Hurley <john.hurley@...ronome.com>
Both the actions and tunnel_conf files contain local functions that check
the type of an input netdev. In preparation for re-use with tunnel offload
via indirect blocks, move these to static inline functions in a header
file.
