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]

- Set the number of large groups to 20.

  Then run devlink reload command to apply the new value.

- Read the number of large groups in flow table.

When using port mirroring, we forward the traffic to another table and
use that table to forward to the mirrored vport. Since the hardware
loses the values of reg c, and in particular reg c0, we fail the match
on the input vport which previously existed in reg c0. To overcome this
situation, we use a set of per vport tables, positioned at the lowest
priority, and forward traffic to those tables. Since these tables are
per vport, we can avoid matching on reg c0.

====================
rework phylink interface for split MAC/PCS support

The following series changes the phylink interface to allow us to
better support split MAC / MAC PCS setups.  The fundamental change
required for this turns out to be quite simple.

Today, mac_config() is used for everything to do with setting the
parameters for the MAC, and mac_link_up() is used to inform the
MAC driver that the link is now up (and so to allow packet flow.)
mac_config() also has had a few implementation issues, with folk
who believe that members such as "speed" and "duplex" are always
valid, where "link" gets used inappropriately, etc.

With the proposed patches, all this changes subtly - but in a
backwards compatible way at this stage.

We pass the the full resolved link state (speed, duplex, pause) to
mac_link_up(), and it is now guaranteed that these parameters to
this function will always be valid (no more SPEED_UNKNOWN or
DUPLEX_UNKNOWN here - unless phylink is fed with such things.)

Drivers should convert over to using the state in mac_link_up()
rather than configuring the speed, duplex and pause in the
mac_config() method. The patch series includes a number of MAC
drivers which I've thought have been easy targets - I've left the
remainder as I think they need maintainer input. However, *all*
drivers will need conversion for future phylink development.

v2: add ocelot/felix and qca/ar9331 DSA drivers to patch 2, add
  received tested-by so far.
