Control BAR pointer is used to unmask interrupts so it should be
in the first cacheline of adapter structure.

Move all data path information into a separate structure. This way
we will be able to allocate new data path with all new rings etc.
and swap it in easily.
No functional changes.

PF services multiple ports using single PCI device therefore
IRQs can no longer be allocated in the netdev code. Lower
portion of the driver has to allocate the IRQs and hand them
out to ports.

number to DebugFS paths.

Support for the PF driver is about to be added and will share
much of the code. When the VF driver was added we planned to
maintain the PF driver as a separate module but have decided
that for our simple use case just maintaining a single module
is more reasonable. Rename the driver to just "nfp" and update
the Kconfig.
While at it remove latent references to NFP3200.

Add missing ABI defines and eBPF instructions to allow
mark to be passed on and extend prepend parsing on the
RX path to pick it up from packet metadata.

Be more strict about FW versions. Drop support for old
transitional revisions which were never used in production.
Dropping support for FW ABI version 0.0.0.0 is particularly
useful because 0 could just be uninitialized memory.
