Move IRQ configuration for IP101A/G from config_init to config_intr
callback. Reasons:

1. This allows phylib to disable interrupts if needed.
2. Icplus was the only driver supporting interrupts w/o defining a
   config_intr callback. Now we can add a phylib plausibility check
   disabling interrupt mode if one of the two irq-related callbacks
   isn't defined.

I don't own hardware with this PHY, and the change is based on the
datasheet for IP101A LF (which is supposed to be register-compatible
with IP101A/G). Change is compile-tested only.

nfp: abm: track all Qdiscs

Our Qdisc offload so far has been very simplistic.  We held
and array of marking thresholds and statistics sized to the
number of PF queues.  This was sufficient since the only
configuration we supported was single layer of RED Qdiscs
(on top of MQ or not, but MQ isn't really about queuing).

As we move to add more Qdiscs it's time to actually try to
track the full Qdisc hierarchy.  This allows us to make sure
our offloaded configuration reflects the SW path better.
We add graft notifications to MQ and RED (PRIO already sends
them) to allow drivers offloading those to learn how Qdiscs
are linked.  MQ graft gives us the obvious advantage of being
able to track when Qdiscs are shared or moved.  It seems
unlikely HW would offload RED's child Qdiscs but since the
behaviour would change based on linked child we should
stop offloading REDs with modified child.  RED will also
handle the child differently during reconfig when limit
parameter is set - so we have to inform the drivers about
the limit, and have them reset the child state when
appropriate.

The NFP driver will now allocate a structure to track each
Qdisc and link it to its children.  We will also maintain
a shadow copy of threshold settings - to save device writes
and make it easier to apply defaults when config is
re-evaluated.

In preparation of handling more Qdisc types switch to a different
offload strategy.  We have now recreated the Qdisc hierarchy in
the driver.  Every time the hierarchy changes parse it, and update
the configuration of the HW accordingly.

While at it drop the support of pretending that we can instantiate
a single queue on a multi-queue device in HW/FW.  MQ is now required,
and each queue will have its own instance of RED.

RED qdisc will replace its child Qdisc with a new FIFO queue if
it is reconfigured and the limit parameter is not 0.

This means that when it's created with limit of 0 it will have no FIFO,
and all packets will be dropped.  If it's changed and limit is specified
it will loose its existing child (implicit graft).  Make sure we mark
RED Qdisc child as NFP_QDISC_UNTRACKED if its not the expected FIFO.

qdisc which will be destroyed.

Using graft notifications recreate in the driver the full Qdisc
hierarchy.  Keep track of how many times each Qdisc is attached
to the hierarchy to make sure we don't offload Qdiscs which are
attached multiple times (device queues can't be shared).  For
graft events of Qdiscs we don't know exist make the child as
invalid/untracked.

Note that MQ Qdisc doesn't send destruction events reliably when
device is dismantled, so we need to manually clean out the
children otherwise we'd think Qdiscs which are still in use

UserPriority since both User Priority and VLAN ID are passed in the
same 'vlan' parameter.

Example:

Each slave has it's own receive timestamp filter. But cpts rx/tx
timestamp enable flags are used to allow ts retrieve only for one
user. This limitation causes data path redundancy and setting overlap
if cpsw module is in dual-mac mode for instance.

If rx ts is enabled only for one port - the second interface must expect
every incoming packet to be PTP packet w/o absolutely any reason, and if
it's PTP - do unneeded stuff, as rx filter for second port is not set
and cpts fifo is not supposed to contain appropriate ts event.
That's not correct.

So, to fix control overlap and avoid redundant CPU cycles, the patch
splits rx/tx ts enable flags between network devices. After the patch,
PTP timestamping still should be used for only one port (or PTP id
counter has to be different for both ports as cpts IP is common).

sctp sk_reuseport allows multiple socks to listen on the same port and

much as TCP/UDP does, the only difference is that sctp is multi-homing

otherwise listen() will return err.

Pull x86 fixes from Thomas Gleixner:
 "A set of x86 fixes:

   - Cure the LDT remapping to user space on 5 level paging which ended
     up in the KASLR space

   - Remove LDT mapping before freeing the LDT pages

   - Make NFIT MCE handling more robust

   - Unbreak the VSMP build by removing the dependency on paravirt ops

   - Support broken PIT emulation on Microsoft hyperV

   - Don't trace vmware_sched_clock() to avoid tracer recursion
