Since in an NPI/DSA setup, not all ports will have the same MTU, we need
to make sure the watermarks for pause frames and/or tail dropping logic
that existed in the driver is still coherent for the new MTU values.
We need to do this because the NPI (aka external CPU) port needs an
increased MTU for the DSA tag. This will be done in a future patch.

It doesn't make sense to rewrite all these registers every time the PHY
library notifies us about a link state change.
In a future patch we will customize the MTU for the CPU port, and since
the MTU was previously configured from adjust_link, if we don't make
this change, its value would have got overridden.

The adjust_link routine should be generic enough to be (re)used by
any SoC that integrates a switch core compatible with the Ocelot
core switch driver. Currently all configurations are generic except
for the PCS settings that are SoC specific. Move these out to the
Ocelot SoC/board instance.

Coalesce logic currently increments the number of packets and sets the
IC bit when the coalesced packets have passed a given limit. This does
not reflect very well what coalesce was meant for as we can have a large
number of packets that are coalesced and then a single one, sent later
on that has the IC bit.
Rework the logic so that it coalesces only upon a limit of packets and
sets the IC bit for large number of packets.

RFA and RFD should not be dependent on FIFO size. In fact, the more FIFO
space we have, the later we can activate Flow Control. Let's use
hard-coded values for RFA and RFD for all FIFO sizes with the exception
of 4k, which is a special case.

Commit 0c3cbbf96def ("mlxsw: Add specific trap for packets routed via
invalid nexthops") allocated an adjacency entry during driver
initialization whose purpose is to discard packets hitting the route
pointing to it.
These adjacency entries are allocated from a resource called KVD linear
(KVDL). There are situations in which the user can decide to set the
size of this resource (via devlink-resource) to 0, in which case the
driver will not be able to load.
Therefore, instead of pre-allocating this adjacency entry, simply
allocate it only when needed. A variable indicating the validity of the
entry is added and is used to ensure it is only allocated and written
once and that it is freed after all the routes were flushed.

There are various of flows which require tids flushing
(disconnection, suspend, etc...).
Currently, when the driver instructs the FW to flush
he masks all the data tids(0-7).
However, the driver doesn't set the management tid (#15)
which cause the FW not to flush it.
When the FW tries to remove the mgmt queue he throws an assert
since it is not an empty queue.
instead of just set only the data tids set everything and let
the FW ignore the invalid tids.

Traffic for a CGX mapped NIXLF can be stopped by disabling entries
in NPC MCAM or by configuring CGX and mailbox messages exist for the
two options. If traffic is stopped at CGX then VFs of that PF are
also effected hence CGX traffic should be started/stopped by
tracking all the users of it. This patch implements that CGX users
tracking. CGX is also configured along with NPC if required.
Also removed a check which mandates even number of LBK VFs.
