Merge branch 'nfp-abm-add-basic-support-for-advanced-buffering-NIC'
Jakub Kicinski says:
====================
nfp: abm: add basic support for advanced buffering NIC
This series lays groundwork for advanced buffer management NIC feature.
It makes necessary NFP core changes, spawns representors and adds devlink
glue. Following series will add the actual buffering configuration (patch
series size limit).
First three patches add support for configuring NFP buffer pools via a
mailbox. The existing devlink APIs are used for the purpose.
Third patch allows us to perform small reads from the NFP memory.
The rest of the patch set adds eswitch mode change support and makes
the driver spawn appropriate representors.
