Subject: [PATCH net-next 06/11] nfp: introduce dev_info static chip data
From: Jakub Kicinski <jakub.kicinski@...ronome.com>
In preparation for supporting new chip add a driver data structure
which will hold per-chip-version information such as register
offsets.
Plumb it through to the relevant functions (nfpcore and nfp_net).
For now only a very simple member holding chip names is added,
following commits will add more.
