When we set the BASET registers of i225 with a base_time in the
future, i225 will "hold" all packets until that base_time is reached,
causing a lot of TX Hangs.
As this behaviour seems contrary to the expectations of the IEEE
802.1Q standard (section 8.6.9, especially 8.6.9.4.5), let's start by
rejecting these types of schedules. If this is too limiting, we can
for example, setup a timer to configure the BASET registers closer to
the start time, only blocking the packets for a "short" while.

Many TSN features depend on the internal PTP clock, so the internal
PTP jumping when the adapter is reset can cause problems, usually in
the form of "TX Hangs" warnings in the driver.
The solution is to save the PTP time before a reset and restore it
after the reset is done. The value of the PTP time is saved before a
reset and we use the difference from CLOCK_MONOTONIC from reset time
to now, to correct what's going to be the new PTP time.
This is heavily inspired by commit bf4bf09bdd ("i40e: save PTP time
before a device reset").

Add XDP support to the IGB driver.
The implementation follows the IXGBE XDP implementation
closely and I used the following patches as basis:
1. commit 9247080816 ("ixgbe: add XDP support for pass and drop actions")
2. commit 33fdc82f08 ("ixgbe: add support for XDP_TX action")
3. commit ed93a39871 ("ixgbe: tweak page counting for XDP_REDIRECT")
Due to the hardware constraints of the devices using the
IGB driver we must share the TX queues with XDP which
means locking the TX queue for XDP.
I ran tests on an older device to get better numbers.
Test machine:
Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores)
2x Intel I211
Routing Original Driver Network Stack: 382 Kpps
Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps
XDP Drop: 1.48 Mpps
Using XDP we can achieve line rate forwarding even on
an older Intel Atom CPU.

Previously intel_dump_pipe_config() used to dump the full crtc state
whether or not the crtc was logically enabled or not. As that meant
occasionally dumping confusing stale garbage I changed it to
check whether the crtc is logically enabled or not. However I did
not realize that the state checker readout code does not
populate crtc_state.hw.{active,enabled}. Hence the state checker
dump would only give us a full dump of the sw state but not the hw
state. Fix that by populating those bits of the hw state as well.

To enable address space sharing with the IOMMU, introduce
arm64_mm_context_get() and arm64_mm_context_put(), that pin down a
context and ensure that it will keep its ASID after a rollover. Export
the symbols to let the modular SMMUv3 driver use them.
Pinning is necessary because a device constantly needs a valid ASID,
unlike tasks that only require one when running. Without pinning, we would
need to notify the IOMMU when we're about to use a new ASID for a task,
and it would get complicated when a new task is assigned a shared ASID.
Consider the following scenario with no ASID pinned:
1. Task t1 is running on CPUx with shared ASID (gen=1, asid=1)
2. Task t2 is scheduled on CPUx, gets ASID (1, 2)
3. Task tn is scheduled on CPUy, a rollover occurs, tn gets ASID (2, 1)
We would now have to immediately generate a new ASID for t1, notify
the IOMMU, and finally enable task tn. We are holding the lock during
all that time, since we can't afford having another CPU trigger a
rollover. The IOMMU issues invalidation commands that can take tens of
milliseconds.
It gets needlessly complicated. All we wanted to do was schedule task tn,
that has no business with the IOMMU. By letting the IOMMU pin tasks when
needed, we avoid stalling the slow path, and let the pinning fail when
we're out of shareable ASIDs.
After a rollover, the allocator expects at least one ASID to be available
in addition to the reserved ones (one per CPU). So (NR_ASIDS - NR_CPUS -
1) is the maximum number of ASIDs that can be shared with the IOMMU.

udp_tunnel: convert Intel drivers with shared tables
This set converts Intel drivers which have the ability to spawn
multiple netdevs, but have only one UDP tunnel port table.
Appropriate support is added to the core infra in patch 1,
followed by netdevsim support and a selftest.
The table sharing works by core attaching the same table
structure to all devices sharing the table. This means the
reference count has to accommodate potentially large values.
Once core is ready i40e and ice are converted. These are
complex drivers, but we got a tested-by from Aaron, so we
should be good :)
Compared to v1 I've made sure the selftest is executable.
Other than that patches 8 and 9 are actually from the Mellanox
conversion series were kept out to avoid Mellanox vs Intel
conflicts.
Last patch is new, some docs to let users knows ethtool
can now display UDP tunnel info.

and how to dump port table via ethtool.

Convert ice to the new infra, use share port tables.
Leave a tiny bit more error checking in place than usual,
because this driver really does quite a bit of magic.
We need to calculate the number of VxLAN and GENEVE entries
the firmware has reserved.
Thanks to the conversion the driver will no longer sleep in
an atomic section.
