smp_processor_id() should not be used in migration-enabled contexts. We
originally thought it was OK in the specific situation of this driver,
but it was wrong, and calling smp_processor_id() in a migration-enabled
context prints a big fat warning when CONFIG_DEBUG_PREEMPT=y.
Therefore, this commit replaces the smp_processor_id() in
migration-enabled contexts by the appropriate get_cpu/put_cpu sections.

This commit removes the useless remove
mvpp2_bm_cookie_{build,pool_get} functions. All what
mvpp2_bm_cookie_build() was doing is compute a 32-bit value by
concatenating the pool number and the CPU number... only to get the pool
number re-extracted by mvpp2_bm_cookie_pool_get() later on.
Instead, just get the pool number directly from RX descriptor status,
and pass it to mvpp2_pool_refill() and mvpp2_rx_refill().
This has the added benefit of dropping a smp_processor_id() call in a
migration-enabled context, which is wrong, and is the original
motivation for making this change.

Once firmware indicates that a given VF is malicious and until
that VF passes an FLR all bets are off - PF can't know anything
is happening to the VF [since VF can't communicate anything to its PF].
But PF is currently still periodically asking device to collect

Once txvlan is disabled, VF would start getting SKBs for transmission

LL2 today is interrupt driven - when tx/rx completion arrives [or any
other indication], qed needs to operate on the connection and pass
the information to the protocol-driver [or internal qed consumer].
Since we have several flavors of ll2 employeed by the driver,
each handler needs to do an if-else to determine the right functionality
to use based on the connection type.
In order to make things more scalable [given that we're going to add
additional types of ll2 flavors] move the infrastrucutre into using
a callback-based approach - the callbacks would be provided as part
of the connection's initialization parameters.

The fact that RTsym table is cached inside nfp_cpp handle is
a relic of old times when nfpcore was a library module. All
the nfp_cpp "caches" are awkward to deal with because of
concurrency and prone to keeping stale information. Make
the run time symbol table be an object read out from the device
and managed by whoever requested it. Since the driver loads
FW at ->probe() and never reloads, we can hold onto the table
for ever.

The ipvlan code already knows how to detect when a duplicate address is
about to be assigned to an ipvlan device. However, that failure is not
propogated outward and leads to a silent failure.
Introduce a validation step at ip address creation time and allow device
drivers to register to validate the incoming ip addresses. The ipvlan
code is the first consumer. If it detects an address in use, we can
return an error to the user before beginning to commit the new ifa in
the networking code.
This can be especially useful if it is necessary to provision many
ipvlans in containers. The provisioning software (or operator) can use
this to detect situations where an ip address is unexpectedly in use.
