Since most or the devlink attributes, parameters, etc are named as nouns 
or verbs (e.g. roce, running, rate, err_count, enable_sriov, etc), 
seeing this term in an adjective form is a bit jarring.  This may seem 
like a picky thing, but can we use "migrate" or "migration" throughout 
this patch rather than "migratable"?

I would prefer to see 'mig' spelled out as 'migration'
