It is less likely for cache line sizes to be 22 or 50, and more likely for
them to be 16 or 32. Also, as far as I understand, cache line size is used for

When multiplexling a MAD sent from VF, we should convert the port used

This is needed under VPI for single ported VFs, since the code that builds
the AH (mlx4_ib_query_ah()) makes decisions based on the input port. If we
use the port number provided by the guest, it might have different protocol
vs. the one this packat has to go from, and hence the result could be wrong.
So far, the conversion was done after the AH was built and it worked for
single ported Eth VFs which were not enabled under VPI. When adding support

port used is port 2). As such, we need to convert the port provided
by the VF to the physical port before calling into the firmware.
It turns out that the Linux mlx4 VF RoCE driver maintains a copy of
the GID table and hence this change became critical only for single
ported IB VFs, but it could be needed for other RoCE VF drivers too.

Jesper Dangaard Brouer says:
====================
pktgen: cleanups and introducing new samples/pktgen scripts
v3:
- Aborted v2 send due it was not generating diff stat
(this is a bug in stg-mail, if not in the root directory)
v2: address nitpicks from Cong Wang
- Remove useless cat's, but keep them for old pgset()
- Comment on: Due to pgctrl, cannot use exit code $? from grep
- Use arithmetic compare in pktgen_sample03_burst_single_flow.sh
This patchset is focused on making pktgen easier to use and better
documented. It contains a number of documentation updates and minor
changes to pktgen. The major contribution is introduction of common
helper function for sample scripts.
Instead of the old pgset() function, three new shell functions for
configuring the different components of pktgen are introduced:
pg_ctrl(), pg_thread() and pg_set().
The new functions correspond to pktgens different components.
* pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
* pg_thread() control the kernel threads and binding to devices
* pg_set() control setup of individual devices
Helpers also provide consistent parameter parsing across the sample
scripts.
Usage example:
./pktgen_sample01_simple.sh -i eth41 -m 00:12:C0:02:AC:5A -d 192.168.41.2
Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
-i : ($DEV) output interface/device (required)
-s : ($PKT_SIZE) packet size
-d : ($DEST_IP) destination IP

net: core: 'ethtool' issue with querying phy settings
When trying to configure the settings for PHY1, using commands
like 'ethtool -s eth0 phyad 1 speed 100', the 'ethtool' seems to
modify other settings apart from the speed of the PHY1, in the
above case.
The ethtool seems to query the settings for PHY0, and use this
as the base to apply the new settings to the PHY1. This is
causing the other settings of the PHY 1 to be wrongly
configured.
The issue is caused by the '_ethtool_get_settings()' API, which
gets called because of the 'ETHTOOL_GSET' command, is clearing
the 'cmd' pointer (of type 'struct ethtool_cmd') by calling
memset. This clears all the parameters (if any) passed for the
'ETHTOOL_GSET' cmd. So the driver's callback is always invoked
with 'cmd->phy_address' as '0'.
The '_ethtool_get_settings()' is called from other files in the
'net/core'. So the fix is applied to the 'ethtool_get_settings()'
which is only called in the context of the 'ethtool'.

bridge: fix parsing of MLDv2 reports
When more than a multicast address is present in a MLDv2 report, all but
the first address is ignored, because the code breaks out of the loop if
there has not been an error adding that address.
This has caused failures when two guests connected through the bridge
tried to communicate using IPv6. Neighbor discoveries would not be
transmitted to the other guest when both used a link-local address and a
static address.
This only happens when there is a MLDv2 querier in the network.
The fix will only break out of the loop when there is a failure adding a
multicast address.

ipv4: Avoid crashing in ip_error
ip_error does not check if in_dev is NULL before dereferencing it.
IThe following sequence of calls is possible:
CPU A CPU B
ip_rcv_finish
ip_route_input_noref()
ip_route_input_slow()
inetdev_destroy()
dst_input()
With the result that a network device can be destroyed while processing
an input packet.
A crash was triggered with only unicast packets in flight, and
forwarding enabled on the only network device. The error condition
was created by the removal of the network device.
As such it is likely the that error code was -EHOSTUNREACH, and the
action taken by ip_error (if in_dev had been accessible) would have
been to not increment any counters and to have tried and likely failed
to send an icmp error as the network device is going away.
Therefore handle this weird case by just dropping the packet if
!in_dev. It will result in dropping the packet sooner, and will not
result in an actual change of behavior.

Hence add a feature flag indicating that the

and doesn't cause any regressions from user
perspective.

ath10k: enable pci soc powersaving
By using SOC_WAKE register it is possible to bring
down power consumption of QCA61X4 from 36mA to
16mA when associated and idle.
Currently the sleep threshold/grace period is at a
very conservative value of 60ms.
Contrary to QCA61X4 the QCA988X firmware doesn't
have Rx/beacon filtering available for client mode
and SWBA events are used for beaconing in AP/IBSS
so the SoC needs to be woken up at least every
~100ms in most cases. This means that QCA988X
is at a disadvantage and the power consumption
won't drop as much as for QCA61X4.
Due to putting irq-safe spinlocks on every MMIO
read/write it is expected this can cause a little
performance regression on some systems. I haven't
done any thorough measurements but some of my
tests don't show any extreme degradation.
The patch removes some explicit pci_wake calls

Input: smtpe-ts - wait 50mS until polling for pen-up
Wait a little bit longer, 50mS instead of 20mS, until the driver starts
polling for pen-up. The problematic behavior before this patch is applied
is as follows. The behavior was observed on the STMPE610QTR controller.
Upon a physical pen-down event, the touchscreen reports one set of x-y-p
coordinates and a pen-down event. After that, the pen-up polling is
triggered and since the controller is not ready yet, the polling mistakenly
detects a pen-up event while the physical state is still such that the pen
is down on the touch surface.
The pen-up handling flushes the controller FIFO, so after that, all the
samples in the controller are discarded. The controller becomes ready
shortly after this bogus pen-up handling and does generate again a pen-down
interrupt. This time, the controller contains x-y-p samples which all read
as zero. Since pressure value is zero, this set of samples is effectively
ignored by userland.
In the end, the driver just bounces between pen-down and bogus pen-up
handling, generating no useful results. Fix this by giving the controller a
bit more time before polling it for pen-up.

Input: joydev - don't classify the vmmouse as a joystick
Joydev is currently thinking some absolute mice are joystick, and that
messes up games in VMware guests, as the cursor typically gets stuck in
the top left corner.
Try to detect the event signature of a VMmouse input device and back off
for such devices. We're still incorrectly detecting, for example, the
VMware absolute USB mouse as a joystick, but adding an event signature
matching also that device would be considerably more risky, so defer that
to a later merge window.
