IP header checksum is calcalated by network layer in default.
To support software TSO, it is better to use HW calculate the
IP header checksum.
FEC hw checksum feature request the checksum field in frame
is zero, otherwise the calculative CRC is not correct.
For segmentated TCP packet, HW calculate the IP header checksum again,
it doesn't bring any impact. For SW TSO, HW calculated checksum bring
better performance.

Make the code more readable and easy to support other features like

And the patch also factorize the getting BD index to it own function.

Some fields in "struct net_bridge" aren't available when compiling the
kernel without IPv6 support. Therefore adding a check/macro to skip the
complaining code sections in that case.

"New smatch warnings:
net/bridge/br_multicast.c:1368 br_ip6_multicast_query() error:
we previously assumed 'group' could be null (see line 1349)"
In the rare (sort of broken) case of a query having a Maximum
Response Delay of zero, we could create a potential null pointer
dereference.
Fixing this by skipping the multicast specific MLD Query parsing again
if no multicast group address is available.

A malicious VF might try to starve the other VFs & PF by creating
contineous doorbell floods. In order to negate this, HW has a threshold of
doorbells per client, which will stop the client doorbells from arriving
if crossed.
The threshold currently configured for VFs is too low - under extreme traffic
scenarios, it's possible for a VF to reach the threshold and thus for its
fastpath to stop working.

Consider the scenario:
For a TCP-style socket, while processing the COOKIE_ECHO chunk in
sctp_sf_do_5_1D_ce(), after it has passed a series of sanity check,
a new association would be created in sctp_unpack_cookie(), but afterwards,
some processing maybe failed, and sctp_association_free() will be called to
free the previously allocated association, in sctp_association_free(),
sk_ack_backlog value is decremented for this socket, since the initial
value for sk_ack_backlog is 0, after the decrement, it will be 65535,
a wrap-around problem happens, and if we want to establish new associations
afterward in the same socket, ABORT would be triggered since sctp deem the
accept queue as full.
Fix this issue by only decrementing sk_ack_backlog for associations in
the endpoint's list.

Generic detection leads to too many false positives, so drop it. FWIW
sensors-detect does not have such generic detection. If the user wants
to force the driver to bind to a not yet supported chip, he/she can
still do so using sysfs attribute new_device.

All devices supported by ina2xx are bidirectional and report the
measured shunt voltage and power values as a signed 16 bit, but the
current driver implementation caches all registers as u16, leading
to an incorrect sign extension when reporting to userspace in
ina2xx_get_value().
This patch fixes the problem by casting the signed registers to s16.
Tested on an INA219.

Caching dso data file descriptors to avoid expensive re-opens
especially during DWARF unwind.
We keep dsos data file descriptors open until their count reaches
the half of the current fd open limit (RLIMIT_NOFILE). In this case
we close file descriptor of the first opened dso object.
We've got overall speedup (~27% for my workload) of report:

When configuring event perf checked a wrong condition that user
specified both of freq (-F) and period (-c) or the event has no
default value. This worked because most of events don't have default
value and only tracepoint events have default of 1 (and it's not
desirable to change it for those events).
However, Andi's downloadable event patch changes the situation so it
cannot change the value for those events. Fix it by allowing override
the default value if user gives one of the options.
$ perf record -a -e uops_retired.all -F 4000 sleep 1

do_posix_clock_monotonic_gettime() is a leftover from the initial
posix timer implementation which maps to ktime_get_ts() and returns
the monotonic time in a timespec.
Use ktime based ktime_get() and use the ktime_delta_us() function to
calculate the delta instead of open coding the timespec math.

This patch will verify the pin's coverter selection for an active stream
when an unsol event reports this pin becomes available again after a display
mode change or hot-plug event.
For Haswell+ and Valleyview: display mode change or hot-plug can change the
transcoder:port connection and make all the involved audio pins share the 1st
converter. So the stream using 1st convertor will flow to multiple pins
but active streams using other converters will fail. This workaround
is to assure the pin selects the right conveter and an assigned converter is
not shared by other unused pins.

struct for all platform.
Cancel the optimization of compiler for struct snd_compr_avail
which size will be 0x1c in 32bit kernel while 0x20 in 64bit
kernel under the optimizer. That will make compaction between
32bit and 64bit. So add packed to fix the size of struct
snd_compr_avail to 0x1c for all platform.

These defconfigs contain the CONFIG_M25P80 symbol, which is now
dependent on the MTD_SPI_NOR symbol. Add CONFIG_MTD_SPI_NOR to the
relevant defconfigs.
At the same time, drop the now-nonexistent CONFIG_MTD_CHAR symbol.

We have a number of front-end drivers for SDHCI_PLTFM, some of them
use 'select MMC_SDHCI_PLTFM', others use 'depends on'. This is
inconsistent and confusing, and in one case has also led to a
build error because of incomplete dependencies:
warning: (MMC_SDHCI_PXAV3 && MMC_SDHCI_PXAV2 && MMC_SDHCI_BCM_KONA) selects MMC_SDHCI_PLTFM which has unmet direct dependencies (MMC && MMC_SDHCI)
drivers/built-in.o: In function `sdhci_sirf_resume':
:(.text+0xaaacb4): undefined reference to `sdhci_resume_host'
drivers/built-in.o: In function `sdhci_sirf_suspend':
:(.text+0xaaacf8): undefined reference to `sdhci_suspend_host'
drivers/built-in.o: In function `sdhci_sirf_probe':
:(.text+0xaaaf44): undefined reference to `sdhci_add_host'
:(.text+0xaaaf50): undefined reference to `sdhci_remove_host'
This changes Kconfig to use 'depends on MMC_SDHCI_PLTFM' for all these
cases, to fix the build error and make the logic more logical.

The MMC host driver should not select the pmic driver, since that
may have other dependencies, notably i2c in this case. It's not
clear what the exact requirement of the driver is, but to preserve
the behavior, this patch changes the 'select' into 'depends on',
meaning you now have to turn on TPS65010 explicitly and then
MMC_OMAP.
Found during randconfig build testing.

gcc correctly points out that hw_state can be used uninitially
in the mvsd_setup_data() function. This rearranges the function
to ensure it always contains a proper value.
