We need to record the number of segments that will be generated when this
frame is segmented. The expectation is that if gso_size is set then
gso_segs is set as well. Without this some drivers such as ixgbe get
confused if they attempt to offload this as they record 0 segments for the
entire packet instead of the correct value.

When computing the bitrate using values read from an SFP module EEPROM,
we use the nominal BR plus BR,min and BR,max to determine the
boundaries. But in some cases BR,min and BR,max aren't provided, which
led the SFP code to end up having the nominal value for both the minimum
and maximum bitrate values. When using a passive cable, the nominal
value should be used as the maximum one, and there is no minimum one
so we should use 0.

The current code already forwards the VF MAC address to the PF, except
in one case. If the VF driver gets a valid MAC address from the firmware
during probe time, it will not forward the MAC address to the PF,
incorrectly assuming that the PF already knows the MAC address. This
causes "ip link show" to show zero VF MAC addresses for this case.
This assumption is not correct. Newer firmware remembers the VF MAC
address last used by the VF and provides it to the VF driver during
probe. So we need to always forward the VF MAC address to the PF.
The forwarded MAC address may now be the PF assigned MAC address and so we
need to make sure we approve it for this case.

For SFP+ modules, 0xA2 page is available only when Diagnostic Monitoring

to read optical diagnostics support at offset 92(0x5c) and set eeprom_len
length to ETH_MODULE_SFF_8436_LEN (to exclude A2 page), if dianostics is
not supported.
Also in bnxt_get_module_info(), module id is read from offset 0x5e which
is not correct. It was working by accident, as offset was not effective
without setting enables flag in the firmware request. SFP module id is
present at location 0. Fix this by removing the offset and read it

A recent change to reduce delay granularity waiting for firmware
reponse has caused a regression. With a tighter delay loop,
the driver may see the beginning part of the response faster.
The original 5 usec delay to wait for the rest of the message
is not long enough and some messages are detected as invalid.
Increase the maximum wait time from 5 usec to 20 usec. Also, fix
the debug message that shows the total delay time for the response
when the message times out. With the new logic, the delay time
is not fixed per iteration of the loop, so we define a macro to
show the total delay time.

Fix `[drm:intel_enable_lvds] *ERROR* timed out waiting for panel to
power on` in kernel log at boot time.
Toshiba Satellite Z930 laptops needs between 1 and 2 seconds to power
on its screen during Intel i915 DRM initialization. This currently
results in a `[drm:intel_enable_lvds] *ERROR* timed out waiting for
panel to power on` message appearing in the kernel log during boot
time and when stopping the machine.
This change increases the timeout of the `intel_enable_lvds` function
from 1 to 5 seconds, letting enough time for the Satellite 930 LCD
screen to power on, and suppressing the error message from the kernel
log.
This patch has been successfully tested on Linux 4.14 running on a
Toshiba Satellite Z930.

code and properly cover the max hw timeout of ~4 seconds, and

a particulary surprising issue, nor specific to that one machine]

During state readout we first read out the pipe src size, store
that information in the user mode h/vdisplay, but later on we overwrite
that with the actual crtc timings. That makes our read out crtc state
inconsistent with itself when the BIOS has enabled the panel fitter to
scale the pipe contents. Let's preserve the pipe src size based
information in the user mode to make things consistent again.
This fixes a problem introduced by commit a2936e3d9a ("drm/i915:
Use drm_mode_get_hv_timing() to populate plane clip rectangle")
where the inconsistent state is now leading the plane clipping code
to report a failure on account the plane dst coordinates not matching
the user mode size. Previously we did the plane clipping based on
the pipe src size instead and thus never noticed the inconsistency.
The failure manifests as a WARN:

On intel_dp_compute_config() we were calculating the needed vco
for eDP on gen9 and we stashing it in
intel_atomic_state.cdclk.logical.vco
However few moments later on intel_modeset_checks() we fully
replace entire intel_atomic_state.cdclk.logical with
dev_priv->cdclk.logical fully overwriting the logical desired
vco for eDP on gen9.
So, with wrong VCO value we end up with wrong desired cdclk, but
also it will raise a lot of WARNs: On gen9, when we read
CDCLK_CTL to verify if we configured properly the desired
frequency the CD Frequency Select bits [27:26] == 10b can mean
337.5 or 308.57 MHz depending on the VCO. So if we have wrong
VCO value stashed we will believe the frequency selection didn't
stick and start to raise WARNs of cdclk mismatch.

In commit 88462d2a78 ("can: flexcan: Remodel FlexCAN register r/w APIs
for big endian FlexCAN controllers.") the following logic was
implemented:
if the dt property "big-endian" is given or
the device is compatible to "fsl,p1010-flexcan":
use big-endian mode;
else
use little-endian mode;
This relies on commit d50f4630c2 ("arm: dts: Remove p1010-flexcan
compatible from imx series dts") which was applied a few commits later.
Without this commit (or an old device tree used for booting a new
kernel) the flexcan devices on i.MX25, i.MX28, i.MX35 and i.MX53 match
the 'the device is compatible to "fsl,p1010-flexcan"' test and so are
switched erroneously to big endian mode.
Instead of the check above put a quirk in devtype data and rely on
of_match_device yielding the most compatible match

bus-off is usually caused by hardware malfunction or configuration error
(baud rate mismatch) and causes a complete loss of communication.
Increase the "bus-off" message's severity from netdev_dbg() to
netdev_info() to make it visible to the user.
A can interface going into bus-off is similar in severity to ethernet's
"Link is Down" message, which is also printed at info level.
It is debatable whether the the "restarted" message should also be
changed to netdev_info() to make the interface state changes
comprehensible from the kernel log. I have chosen to keep the
"restarted" message at dbg for now as the "bus-off" message should be
enough for the user to notice and investigate the problem.

hotplug-cpu.c:(.text+0x12c): undefined reference to `timed_topology_update'
arch/powerpc/platforms/pseries/hotplug-cpu.o: In function `dlpar_cpu_remove':
hotplug-cpu.c:(.text+0x400): undefined reference to `timed_topology_update'
Fix it by moving the empty version of timed_topology_update() into the
existing #ifdef block, which has the right guard of SPLPAR && NUMA.

====================
Aquantia various patches 2018-05
These are two patches covering issues found during test cycles:
First is that driver should declare valid vlan_features
Second fix is about correct allocation of MSI interrupts on some systems.

Driver should use pci_alloc_irq_vectors return value to correct number
of allocated vectors and napi instances. Otherwise it'll panic later
in pci_irq_vector.
Driver also should allow more than one MSI vectors to be allocated.
Error return path from pci_alloc_irq_vectors is also fixed to revert
resources in a correct sequence when error happens.

When the core networking needs to detect the transport offset in a given
packet and parse it explicitly, a full-blown flow_keys struct is used for
storage.
This patch introduces a smaller keys store, rework the basic flow dissect
helper to use it, and apply this new helper where possible - namely in
skb_probe_transport_header(). The used flow dissector data structures
are renamed to match more closely the new role.
The above gives ~50% performance improvement in micro benchmarking around
skb_probe_transport_header() and ~30% around eth_get_headlen(), mostly due
to the smaller memset. Small, but measurable improvement is measured also
in macro benchmarking.
v1 -> v2: use the new helper in eth_get_headlen() and skb_get_poff(),
as per DaveM suggestion

This patch adds driver changes for supporting the Unified Fabric Port
(UFP). This is a new paritioning mode wherein MFW provides the set of
parameters to be used by the device such as traffic class, outer-vlan
tag value, priority type etc. Drivers receives this info via notifications
from mfw and configures the hardware accordingly.

`mf_mode' field indicates the multi-partitioning mode the device is
configured to. This method doesn't scale very well, adding a new MF mode
requires going over all the existing conditions, and deciding whether those
are needed for the new mode or not.
The patch defines a set of bit-fields for modes which are derived according
to the mode info shared by the MFW and all the configuration would be made
according to those. To add a new mode, there would be a single place where
we'll need to go and choose which bits apply and which don't.

The 6341 however has the PHYs at 0x10, 0x11, 0x12. Add a parameter to
the info structure for this base address.
Testing of 6f88284f3b ("net: dsa: mv88e6xxx: Add MDIO interrupts for

Now sctp only delays the authentication for the normal cookie-echo
chunk by setting chunk->auth_chunk in sctp_endpoint_bh_rcv(). But
for the duplicated one with auth, in sctp_assoc_bh_rcv(), it does
authentication first based on the old asoc, which will definitely
fail due to the different auth info in the old asoc.
The duplicated cookie-echo chunk will create a new asoc with the
auth info from this chunk, and the authentication should also be
done with the new asoc's auth info for all of the collision 'A',
'B' and 'D'. Otherwise, the duplicated cookie-echo chunk with auth
will never pass the authentication and create the new connection.
This issue exists since very beginning, and this fix is to make
sctp_assoc_bh_rcv() follow the way sctp_endpoint_bh_rcv() does
for the normal cookie-echo chunk to delay the authentication.
While at it, remove the unused params from sctp_sf_authenticate()
and define sctp_auth_chunk_verify() used for all the places that
do the delayed authentication.
