Flow control is used with 2500Base-X and AQR PHYs to do rate adaptation
between line side 100/1000 links and MAC running at 2.5G.

This is independent of the flow control configuration settled on line

In general, allowing the MAC to handle flow control even if not
negotiated with the link partner should not be a problem, so the patch
just enables it in all cases.

Don't restart PCS AN if link is up already.

Although in theory this feedback loop should be possible with the other
in-band AN modes too, for some reason it was not seen with the VSC8514

We maintain global statistics for an entire MDIO bus, as well as broken
down, per MDIO bus address statistics. Given that it is possible for
MDIO devices such as switches to access MDIO bus addresses for which
there is not a mdio_device instance created (therefore not a a
corresponding device directory in sysfs either), we also maintain
per-address statistics under the statistics folder. The layout looks
like this:

/sys/class/mdio_bus/../statistics/
	transfers
	errrors
	writes
	reads
	transfers_<addr>
	errors_<addr>
	writes_<addr>
	reads_<addr>

When a mdio_device instance is registered, a statistics/ folder is
created with the tranfers, errors, writes and reads attributes which
point to the appropriate MDIO bus statistics structure.

Statistics are 64-bit unsigned quantities and maintained through the
u64_stats_sync.h helper functions.

Currently, Most of the steering tree is statically declared ahead of time,
with steering prios instances allocated for each fdb chain to assign max
number of levels for each of them. This allows fs_core to manage the
connections and  levels of the flow tables hierarcy to prevent loops, but
restricts us with the number of supported chains and priorities.

Introduce unmananged flow tables, allowing the user to manage the flow
table connections. A unamanged table is detached from the fs_core flow
table hierarcy, and is only connected back to the hierarchy by explicit
FTEs forward actions.

This will be used together with firmware that supports ignoring the flow

Previous patches added support for two hardware flags for IPv4 and IPv6
routes: 'RTM_F_OFFLOAD' and 'RTM_F_TRAP'. Both indicate the presence of
the route in hardware. The first indicates that traffic is actually
offloaded from the kernel, whereas the second indicates that packets
hitting such routes are trapped to the kernel for processing (e.g., host
routes).

Use these two flags in mlxsw. The flags are modified in two places.
Firstly, whenever a route is updated in the device's table. This
includes the addition, deletion or update of a route. For example, when
a host route is promoted to perform NVE decapsulation, its action in the
device is updated, the 'RTM_F_OFFLOAD' flag set and the 'RTM_F_TRAP'
flag cleared.

Secondly, when a route is replaced and overwritten by another route, its
flags are cleared.

The driver currently uses the 'RTNH_F_OFFLOAD' flag for both routes and
nexthops, which is cumbersome and unnecessary now that we have separate
flag for the route itself.

Separate the offload indication for nexthops from routes and call it
whenever the offload state within the nexthop group changes.

Note that IPv6 (unlike IPv4) does not share the same nexthop group
between different routes, whereas mlxsw does. Therefore, whenever the
offload indication within an IPv6 nexthop group changes, all the linked
routes need to be updated.
