Subject: [PATCH net-next 03/10] nfp: use callbacks for slow path ring related functions
From: Jakub Kicinski <jakub.kicinski@...ronome.com>
To reduce the coupling of slow path ring implementations and their
callers, use callbacks instead.
Changes to Jakub's work:
* Also use callbacks for xmit functions
