In preparation for supporting multiple MDIO busses, pass the mii_bus
structure to all PHY operations. It will in future then be clear on
which MDIO bus the operation should be performed.
For reads/write from phylib, the mii_bus is readily available. However
some internal code also access the PHY, e.g. for EEE and SERDES. Make
this code use the one and only currently available MDIO bus.

The mv88e6165 family has the internal PHYs mapped directly onto the
SMI register space as the switch. So the registers can be read
directly. Put a wrapper around this, in preparation for changing the
signature in order to support the external MDIO bus of the 6390.

If requesting msi-x interrupts fails in alx_request_irq we fall back to
a single tx queue and msi or legacy interrupts.
Currently the adapter stops working in this case and we get tx watchdog
timeouts. For reasons unknown the adapter gets confused when we load the
dma adresses to the chip in alx_init_ring_ptrs twice: the first time with
multiple queues and the second time in the fallback case with a single
queue.
To fix this move the the call to alx_reinit_rings (which calls
alx_init_ring_ptrs) after alx_request_irq. At this time it is clear how
much tx queues we have and which dma addresses we use.

If requesting msi-x interrupts fails we should fall back to msi or
legacy interrupts. However alx_realloc_ressources don't call
alx_init_intr, so we fail to set the right number of tx queues.
This results in watchdog timeouts and a nonfunctional adapter.

When using the ibmveth driver in a KVM/QEMU based VM, it currently
always prints out a scary error message like this when it is started:
ibmveth 71000003 (unregistered net_device): unable to change
checksum offload settings. 1 rc=-2 ret_attr=71000003
This happens because the driver always tries to enable the checksum
offloading without checking for the availability of this feature first.
QEMU does not support checksum offloading for the spapr-vlan device,
thus we always get the error message here.
According to the LoPAPR specification, the "ibm,illan-options" property
of the corresponding device tree node should be checked first to see
whether the H_ILLAN_ATTRIUBTES hypercall and thus the checksum offloading
feature is available. Thus let's do this in the ibmveth driver, too, so
that the error message is really only limited to cases where something
goes wrong, and does not occur if the feature is just missing.

write-back cache in degraded mode introduces corner cases to the array.
Although we try to cover all these corner cases, it is safer to just
disable write-back cache when the array is in degraded mode.
In this patch, we disable writeback cache for degraded mode:
1. On device failure, if the array enters degraded mode, raid5_error()
will submit async job r5c_disable_writeback_async to disable
writeback;
2. In r5c_journal_mode_store(), it is invalid to enable writeback in
degraded mode;
3. In r5c_try_caching_write(), stripes with s->failed>0 will be handled
in write-through mode.

Write back cache requires a complex RMW mechanism, where old data is
read into dev->orig_page for prexor, and then xor is done with
dev->page. This logic is already implemented in the write path.
However, current read path is not awared of this requirement. When
the array is optimal, the RMW is not required, as the data are
read from raid disks. However, when the target stripe is degraded,
complex RMW is required to generate right data.
To keep read path as clean as possible, we handle read path by
flushing degraded, in-journal stripes before processing reads to
missing dev.
Specifically, when there is read requests to a degraded stripe
with data in journal, handle_stripe_fill() calls
r5c_make_stripe_write_out() and exits. Then handle_stripe_dirtying()
will do the complex RMW and flush the stripe to RAID disks. After
that, read requests are handled.
There is one more corner case when there is non-overwrite bio for
the missing (or out of sync) dev. handle_stripe_dirtying() will not
be able to process the non-overwrite bios without constructing the
data in handle_stripe_fill(). This is fixed by delaying non-overwrite
bios in handle_stripe_dirtying(). So handle_stripe_fill() works on
these bios after the stripe is flushed to raid disks.

For safer operation, all arrays start in write-through mode, which has been
better tested and is more mature. And actually the write-through/write-mode
isn't persistent after array restarted, so we always start array in
write-through mode. However, if recovery found data-only stripes before the
shutdown (from previous write-back mode), it is not safe to start the array in
write-through mode, as write-through mode can not handle stripes with data in
write-back cache. To solve this problem, we flush all data-only stripes in
r5l_recovery_log(). When r5l_recovery_log() returns, the array starts with
empty cache in write-through mode.
This logic is implemented in r5c_recovery_flush_data_only_stripes():
1. enable write back cache
2. flush all stripes
3. wake up conf->mddev->thread
4. wait for all stripes get flushed (reuse wait_for_quiescent)
5. disable write back cache
The wait in 4 will be waked up in release_inactive_stripe_list()
when conf->active_stripes reaches 0.
It is safe to wake up mddev->thread here because all the resource
required for the thread has been initialized.

For some mlx5 HW models (CX4, CX4Lx), the VF driver needs to put part
of the packet headers on the TX descriptor so the e-switch can do proper
matching and steering. This is called "min-inline", it's advertized to
the VF by the FW and also enforced on them by the HW, such that if they
don't obey, their packets are dropped.
SRIOV VF libmlx5 instances should take into account the min-inline
value of their vports. For that end, we provide this value through
the vendor response part of init_ucontext command.
The min inline value is reported in a way which will let newer libmlx5
instances realize that they are running over an older kernel and act
accordingly (e.g apply some educated guess).

The E-Switch FDB size was hard coded to 8k. Change it to be
min(max eswitch table size, max flow counters * num flow groups)
where the max values are read from the firmware and the number of
flow groups is hard-coded as before this change.
We don't know upfront the division of flows to group. This setup allows
each group to be of size up to the where we want to support (we mandate
pairing of flows with counters for offloading). Thus, we don't expect
multiple occurences for a group which in turn adds steering hops.

The idea for this was born when testing VF support in iproute2 which was
impeded by hardware requirements. In fact, not every VF-capable hardware
driver implements all netdev ops, so testing the interface is still hard
to do even with a well-sorted hardware shelf.
To overcome this and allow for testing the user-kernel interface, this
patch allows to turn dummy into a PF with a configurable amount of VFs.
Since my patch series 'bus-agnostic-num-vf' has been accepted,
implementing the required interfaces is pretty straightforward: Iff
'num_vfs' module parameter was given a value >0, a dummy bus type is
being registered which implements the 'num_vf()' callback. Additionally,
a dummy parent device common to all dummy devices is registered which
sits on the above dummy bus.
