Jakub Kicinski 1f5cf1036c nfp: devlink: include vendor/product info in serial number
The manufacturing team requests we include vendor and product
in the serial number field, as the serial number itself is not
unique across manufacturing facilities and products.

Jakub Kicinski 05fe4ab75c nfp: devlink: use the generic manufacture identifier instead of vendor
Vendor may sound ambiguous, let's rename the fab string to
"board.manufacture" (which was just added as a generic identifier).

Ryan C Goodfellow 5948185b97 nfp: devlink port split support for 1x100G CXP NIC
This commit makes it possible to use devlink to split the 100G CXP
Netronome into two 40G interfaces. Currently when you ask for 2
interfaces, the math in src/nfp_devlink.c:nfp_devlink_port_split
calculates that you want 5 lanes per port because for some reason
eth_port.port_lanes=10 (shouldn't this be 12 for CXP?). What we really
want when asking for 2 breakout interfaces is 4 lanes per port. This
commit makes that happen by calculating based on 8 lanes if 10 are
present.

Jakub Kicinski 4afa3af418 nfp: add devlink_eswitch_mode_set callback
Our previous apps all assumed to use only one eswitch mode (legacy
or switchdev) without the ability to change it.  ABM NIC will
want to support the switch so plumb devlink_eswitch_mode_set through.
The devlink_eswitch_mode_set is expected to spawn representors and
potentially devlink ports so it's called under big devlink lock and
pf->lock.

Jiri Pirko 5ec1380a21 devlink: extend attrs_set for setting port flavours
Devlink ports can have specific flavour according to the purpose of use.
This patch extend attrs_set so the driver can say which flavour port
has. Initial flavours are:
physical, cpu, dsa
User can query this to see right away what is the purpose of each port.

Jakub Kicinski bcc93a23ca nfp: register devlink after app is created
Devlink used to have two global locks: devlink lock and port lock,
our lock ordering looked like this:

  devlink lock -> driver's pf->lock -> devlink port lock

After recent changes port lock was replaced with per-instance
lock.  Unfortunately, new per-instance lock is taken on most
operations now.  This means we can only grab the pf->lock from
the port split/unsplit ops.  Lock ordering looks like this:

  devlink lock -> driver's pf->lock -> devlink instance lock

Since we can't take pf->lock from most devlink ops, make sure
nfp_apps are prepared to service them as soon as devlink is
registered.  Locking the pf must be pushed down after
nfp_app_init() callback.

The init order looks like this:
 nfp_app_init
 devlink_register
 nfp_app_start
 netdev/port_register

As soon as app_init is done nfp_apps must be ready to service
devlink-related callbacks.  apps can only register their own
devlink objects from nfp_app_start.

Add initial devlink support.  This patch simply switches allocation
of per-adapter structure to devlink's priv and register devlink
with empty ops table.  See following patches for implementation
of particular ops.

We should now clear the app pointer on exit, this is how devlink
callbacks will know app is not initialized.
