ipvlan_queue_xmit() should return NET_XMIT_XXX, but
ipvlan_xmit_mode_l2/l3() returns rx_handler_result_t or NET_RX_XXX
in some cases. ipvlan_rcv_frame() will only return RX_HANDLER_CONSUMED
in ipvlan_xmit_mode_l2/l3() because 'local' is true. It's equal to
NET_XMIT_SUCCESS. But dev_forward_skb() can return NET_RX_SUCCESS or
NET_RX_DROP, and returning NET_RX_DROP(NET_XMIT_DROP) will increase
both ipvlan and ipvlan->phy_dev drops counter.
The skb to forward can be treated as xmitted successfully. This patch
makes ipvlan_queue_xmit() return NET_XMIT_SUCCESS for forward skb.

"These extend the int340x thermal driver, add thermal DT bindings for
some Qcom platforms, add DT bindings and support for Armada AP807 and
MSM8909, allow selecting the bang-bang thermal governor as the default
one, address issues in several thermal drivers for ARM platforms and
clean up code.

The thermal framework is migrating to the generic trip points. The set
of changes also implies a self-encapsulation of the thermal zone
device structure where the internals are no longer directly accessible
but with accessors.
Use the new API instead, so the next changes can be pushed in the
thermal framework without this driver failing to compile.
No functional changes intended.

efx_net_stats() (.ndo_get_stats64) can be called during an ethtool
selftest, during which time nic_data->mc_stats is NULL as the NIC has
been fini'd. In this case do not attempt to fetch the latest stats
from the hardware, else we will crash on a NULL dereference:
BUG: kernel NULL pointer dereference, address: 0000000000000038
RIP efx_nic_update_stats
abridged calltrace:
efx_ef10_update_stats_pf
efx_net_stats
dev_get_stats
dev_seq_printf_stats
Skipping the read is safe, we will simply give out stale stats.
To ensure that the free in efx_ef10_fini_nic() does not race against
efx_ef10_update_stats_pf(), which could cause a TOCTTOU bug, take the
efx->stats_lock in fini_nic (it is already held across update_stats).

64-bit DMA detection will fail if axienet was started before (by boot
loader, boot ROM, etc). In this state axienet will not start properly.
XAXIDMA_TX_CDESC_OFFSET + 4 register (MM2S_CURDESC_MSB) is used to detect
64-bit DMA capability here. But datasheet says: When DMACR.RS is 1
(axienet is in enabled state), CURDESC_PTR becomes Read Only (RO) and
is used to fetch the first descriptor. So iowrite32()/ioread32() trick
to this register to detect 64-bit DMA will not work.
So move axienet reset before 64-bit DMA detection.

During this series, and to show that as is always the case, things are
never easy as they should be, a hardware issue was found, and it took
some time to find the workaround(s). The bug and workaround are better
explained in patch 4/4.
Note: the workaround has a simpler alternative, but it would involve
adding support for the other timestamp registers, and only using the
TXSTMP{H/L}_0 as a way to clear the interrupt. But I feel bad about
throwing this kind of resources away. Didn't test this extensively but
it should work.
Also, as Marc Kleine-Budde suggested, after some consensus is reached
on this series, most parts of it will be proposed for igb.

Move the list of next hops from struct mlxsw_sp_rif to mlxsw_sp_crif. The
reason is that eventually, next hops for mlxsw uppers should be offloaded
and unoffloaded on demand as a netdevice becomes an upper, or stops being
one. Currently, next hops are tracked at RIFs, but RIFs do not exist when a
netdevice is not an mlxsw uppers. CRIFs are kept track of throughout the
netdevice lifetime.
Correspondingly, track at each next hop not its RIF, but its CRIF (from
which a RIF can always be deduced).
Note that now that next hops are tracked at a CRIF, it is not necessary to
move each over to a new RIF when it is necessary to edit a RIF. Therefore
drop mlxsw_sp_nexthop_rif_migrate() and have mlxsw_sp_rif_migrate_destroy()
call mlxsw_sp_nexthop_rif_update() directly.

Nexthop finalization consists of two steps: the part where the offload is
removed, because the backing RIF is now gone; and the part where the
association to the RIF is severed.
Extract from mlxsw_sp_nexthop_type_fini() a helper that covers the
unoffloading part, mlxsw_sp_nexthop_type_rif_gone(), so that it can later
be called independently.
Note that this swaps around the ordering of mlxsw_sp_nexthop_ipip_fini()
vs. mlxsw_sp_nexthop_rif_fini(). The current ordering is more of a
historical happenstance than a conscious decision. The two cleanups do not
depend on each other, and this change should have no observable effects.

When a RIF is about to be created, the registration of the netdevice that
it should be associated with must have been seen in the past, and a CRIF
created. Therefore make this a hard requirement by looking up the CRIF
during RIF creation, and complaining loudly when there isn't one.
This then allows to keep a link between a RIF and its corresponding
CRIF (and back, as the relationship is one-to-at-most-one), which do.
The CRIF will later be useful as the objects tracked there will be
offloaded lazily as a result of RIF creation.
CRIFs are created when an "interesting" netdevice is registered, and
destroyed after such device is unregistered. CRIFs are supposed to already
exist when a RIF creation request arises, and exist at least as long as
that RIF exists. This makes for a simple invariant: it is always safe to
dereference CRIF pointer from "its" RIF.
To guarantee this, CRIFs cannot be removed immediately when the UNREGISTER
event is delivered. The reason is that if a RIF's netdevices has an IPv6
address, removal of this address is notified in an atomic block. To remove
the RIF, the IPv6 removal handler schedules a work item. It must be safe
for this work item to access the associated CRIF as well.
Thus when a netdevice that backs the CRIF is removed, if it still has a
RIF, do not actually free the CRIF, only toggle its can_destroy flag, which
this patch adds. Later on, mlxsw_sp_rif_destroy() collects the CRIF.

CRIFs are generally not maintained for loopback RIFs. However, the RIF for
the default VRF is used for offloading of blackhole nexthops. Nexthops
expect to have a valid CRIF. Therefore in this patch, add code to maintain
CRIF for the loopback RIF as well.

CRIFs are objects that mlxsw maintains for netdevices that may not have an
associated RIF (i.e. they may not have been instantiated in the ASIC), but
if indeed they do not, it is quite possible they will in the future. These
netdevices are candidate RIFs, hence CRIFs. Netdevices for which CRIFs are
created include e.g. bridges, LAGs, or front panel ports. The idea is that
next hops would be kept at CRIFs, not RIFs, and thus it would be easier to
offload and unoffload the entities that have been added before the RIF was
created.
In this patch, add the code for low-level CRIF maintenance: create and
destroy, and keep in a table keyed by the netdevice pointer for easy
recall.

The current function, mlxsw_sp_router_ul_rif_get(), is a wrapper around the
function mentioned in the subject. As such it forms an external interface
of the router code.
In future patches we will want to maintain connection between RIFs and the
CRIFs (introduced in the next patch) that back them. That will not hold
for the VRF-based loopback netdevices, so the whole CRIF business can be
kept hidden from the rest of mlxsw.
But for the main VRF loopback RIF we do want to keep the RIF-CRIF
connection, because that RIF is used for blackhole next hops, and the next
hop code can be kept simpler for assuming rif->crif is valid.
Hence, instead, call mlxsw_sp_ul_rif_get() to create the main VRF loopback
RIF. This being an internal function will take the CRIF argument anyway.
Furthermore, the function does not lock, which is not necessary at this
point in code yet.

With support for Ethernet PHY LEDs having been added, while
unregistering a MDIO bus and its child device liks PHYs there may be
"late" accesses to the MDIO bus. One typical use case is setting the PHY
LEDs brightness to OFF for instance.
We need to ensure that the MDIO bus controller remains entirely
functional since it runs off the main GENET adapter clock.

On error flow resources being freed in esw_master_egress_destroy_resources()
but pointers not being set to null if error flow is from creating a
bounce rule. Then in esw_acl_egress_ofld_cleanup() we try to access already
freed pointers. Fix it by resetting the pointers to null.
Also if error is from creating a second or later bounce rule then the
flow group and table being used and cannot and should not be freed.
Add a check to destroy the flow group and table if there are no bounce
rules.
