The function removes the FDB entry that directs the macvlan's MAC to the
router port. It is called from both the netdev notifier block and the
inetaddr notifier block that will soon hold the router lock.

Make sure that only the netdev notifier calls the exported version, so
that is will take the router lock, which will already be held by the
inetaddr notifier.

The function that resolves the underlay device of the IPIP tunnel
assumes that RTNL is taken, but this will not be correct when RTNL is
removed from the route insertion path.

Convert the function to use dev_get_by_index_rcu() instead of
__dev_get_by_index() and make sure it is always called from an RCU
read-side critical section.

IPv6 addresses are deleted in an atomic context, so the driver defers
the potential teardown of the associated router interface (RIF) to a
work item that takes RTNL.

The RIF is only destroyed if the associated netdev does not have any IP
addresses (both IPv4 and IPv6). The IPv4 device ('struct in_device') is
currently fetched via __in_dev_get_rtnl() which assumes RTNL is taken.

Since RTNL is going to be removed, convert it to use __in_dev_get_rcu()
from an RCU read-side critical section.

Note that the IPv6 device ('struct inet6_dev') is fetched via
__in6_dev_get(), which does not require RTNL.

In order not to needlessly schedule the work item that updates the
mirroring agents, only schedule it if there are any mirroring agents
present.

This is done by adding an atomic counter that counts the active
mirroring agents.

It is incremented / decremented whenever a mirroring agent is created /
destroyed. It is read before scheduling the work item and in the
devlink-resource occupancy callback.

Previous patch added a work item in the mirroring code that will take
care of updating the active mirroring agents in response to different
events.

Change the mirroring agents update function - mlxsw_sp_span_respin() -
to invoke this work item when called.

Therefore there is no need for callers to schedule a work item
themselves.

The driver updates its mirroring agents whenever it receives a
notification about an event that can affect these. For example, the
addition of a route might require the driver to change the egress port
of an ERSPAN session.

Currently, RTNL needs to be held when these agents are updates, so the
driver either:

1. Calls directly into the mirroring code, in case RTNL is held

2. Schedules a work item that will take RTNL and call into the mirroring
code

Simplify this by having the mirroring code schedule the work item for
the update instead of requiring callers to schedule a work item
themselves.

The conversion of the callers will be done in the next patch to make
review easier.

This will later allow us to remove RTNL from different parts of the
driver. It will also allow us to only schedule the work item in case
there are active mirroring agents, which is information private to the
mirroring code.

The current codebase makes use of the zero-length array language
extension to the C90 standard, but the preferred mechanism to declare
variable-length types such as these ones is a flexible array member[1][2],
introduced in C99:

struct foo {
        int stuff;
        struct boo array[];
};

By making use of the mechanism above, we will get a compiler warning
in case the flexible array does not occur last in the structure, which
will help us prevent some kind of undefined behavior bugs from being
inadvertently introduced[3] to the codebase from now on.

Also, notice that, dynamic memory allocations won't be affected by
this change:

"Flexible array members have incomplete type, and so the sizeof operator
may not be applied. As a quirk of the original implementation of
zero-length arrays, sizeof evaluates to zero."[1]

This issue was found with the help of Coccinelle.

Add support for SQ's FW dump on TX reporter's events. Use Resource dump
API to retrieve the relevant data: SX slice, SQ dump and SQ buffer. Wrap
it in formatted messages and store the binary output in devlink core.

Example:
$ devlink health dump show pci/0000:00:0b.0 reporter tx
