A new function, kernel_sock_ip_overhead(), is provided
to calculate the cumulative overhead imposed by the IP
Header and IP options, if any, on a socket's payload.
The new function returns an overhead of zero for sockets
that do not belong to the IPv4 or IPv6 address families.
This is used in the L2TP code path to compute the
total outer IP overhead on the L2TP tunnel socket when
calculating the default MTU for Ethernet pseudowires.

When qedr is enabled, qed would try dividing the msi-x vectors between
L2 and RoCE, starting with L2 and providing it with sufficient vectors
for its queues.
Problem is qed would also do that for storage partitions, and as those
don't need queues it would lead qed to award those partitions with 0
msi-x vectors, causing them to believe theye're using INTa and
preventing them from operating.

ftgmac100: Rework batch 1 - Link & Interrupts
This is version 2 of the first batch of updates to the
ftgmac100 driver.
Essentially:
- A few misc cleanups
- Fixing link speed & duplex handling (including dealing with
an Aspeed requirement to double reset the controller when
the speed changes)
- And addition of a reset task workqueue which will be used
for delaying the re-initialization of the controller
- Fixing a number of issues with how interrupts and NAPI
are dealt with.
Subsequent batches will rework and improve the rx path, the
tx path, and add a bunch of features and fixes.
Version 2 addresses some review comments to patches 5 and 10

First, don't look at the interrupt status in the poll loop
to decide what to poll. It's wrong. If we have run out of
budget, we may still have RX packets to unqueue but no more
RX interrupt pending.
So instead move the code looking at the interrupt status
into the interrupt handler where it belongs. That avoids a slow
MMIO read in the NAPI fast path. We keep the abnormal interrupts
enabled while NAPI is scheduled.
While at it, actually do something useful in the "error" cases:
On AHB bus error, trigger the new reset task, that's about all
we can do. On RX packet fifo or descriptor overflows, we need
to restart the MAC after having freed things up. So set a flag
that NAPI will see and use to perform that restart after
harvesting the RX ring.
Finally, we shouldn't complete NAPI if there are still outgoing
packets that will need harvesting. Waiting for more interrupts
is less efficient than letting NAPI run a while longer while
the queue drains.

The HW requires a full MAC reset when changing the speed.
Additionally the Aspeed documentation spells out that the
MAC needs to be reset twice with a 10us interval.
We thus move the speed setting and top level reset code
into a new ftgmac100_reset_and_config_mac() function which
handles both. Move the ring pointers initialization there
too in order to reflect the HW change.
Also reduce the timeout for the MAC reset as it shouldn't

Detection of watchdog timeout of Octeon cores is flawed and susceptible to
false alarms. Refactor by removing the detection code, and in its place,
leverage existing code that monitors for an indication from the NIC
firmware that an Octeon core crashed; expand the meaning of the indication
to "an Octeon core crashed or its watchdog timer expired". Detection of
watchdog timeout is now delegated to an exception handler in the NIC
firmware; this is free of false alarms.
Also if there's an Octeon core crash or watchdog timeout:
(1) Disable VF Ethernet links.
(2) Decrement the module refcount by an amount equal to the number of
active VFs of the NIC whose Octeon core crashed or had a watchdog
timeout. The refcount will continue to reflect the active VFs of
other liquidio NIC(s) (if present) whose Octeon cores are faultless.
Item (2) is needed to avoid the case of not being able to unload the driver
because the module refcount is stuck at some non-zero number. There is
code that, in normal cases, decrements the refcount upon receiving a
message from the firmware that a VF driver was unloaded. But in
exceptional cases like an Octeon core crash or watchdog timeout, arrival of
that particular message from the firmware might be unreliable. That normal
case code is changed to not touch the refcount in the exceptional case to
avoid contention (over the refcount) with the liquidio_watchdog kernel
thread who will carry out item (2).

mode_valid() called from drm_helper_probe_single_connector_modes()
may need to look at connector->state because what a valid mode is may
depend on connector properties being set. For example some HDMI modes
might be rejected when a connector property forces the connector
into DVI mode.
Some implementations of detect() already lock all state,
so we have to pass an acquire_ctx to them to prevent a deadlock.
This means changing the function signature of detect() slightly,
and passing the acquire_ctx for locking multiple crtc's.
For the callbacks, it will always be non-zero. To allow callers
not to worry about this, drm_helper_probe_detect_ctx is added
which might handle -EDEADLK for you.
Changes since v1:
- Always set ctx parameter.
Changes since v2:
- Always take connection_mutex when probing.
Changes since v3:
- Remove the ctx from intel_dp_long_pulse, and add
WARN_ON(!connection_mutex) (danvet)
