Subject: [PATCH net-next 00/13] nfp: abm: add basic support for advanced buffering NIC

Hi!

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.

Jakub Kicinski (13):
  nfp: move rtsym helpers to pf code
  nfp: add support for per-PCI PF mailbox
  nfp: add shared buffer configuration
  nfp: core: allow 4-byte aligned accesses to Memory Units
  nfp: abm: add initial active buffer management NIC skeleton
  nfp: abm: create project-specific vNIC structure
  nfp: add app pointer to port representors
  devlink: don't take instance lock around eswitch mode set
  nfp: add devlink_eswitch_mode_set callback
  nfp: abm: spawn port netdevs
  nfp: abm: force Ethternet port up
  nfp: use split in naming of PCIe PF ports
  nfp: assign vNIC id as phys_port_name of vNICs which are not ports
