63a550fc15 net: stmmac: Remove uneeded checks for GMAC version
With the introducion of callbacks check in hwif.h we only call the
callback if HW supports it so there is no longer need to check for GMAC
version.

ab0204e35c net: stmmac: Uniformize the use of dma_{rx/tx}_mode callbacks
Instead of relying on the GMAC version for choosing if we need to use
dma_{rx/tx}_mode or just dma_mode callback lets uniformize this and
always use the dma_{rx/tx}_mode callbacks.

6e03126add Bluetooth: btqca: Add AR3002 rampatch support
This patch adds rampatch download compatibility for ROME >= 3.2.
Starting with ROME 3.2, the 'download mode' field of the rampatch
header indicates if the controller acknowledges (or not) the received
rampatch segments. If not, we need to send all the segments without
expecting any event from the controller (except for the last segment).
Goal is (I assume) to speed-up rampatch download.

This fixes BT on Dragonboard-600c P2 which includes the following BT
controller:

67d8cee432 Bluetooth: use wait_event API instead of open-coding it
I've seen timeout errors from HCI commands where it looks like
schedule_timeout() has returned immediately; additional logging for the
error case gives:

	req_status=1 req_result=0 remaining=10000 jiffies

so the device is still in state HCI_REQ_PEND and the value returned by
schedule_timeout() is the same as the original timeout (HCI_INIT_TIMEOUT
on a system with HZ=1000).

Use wait_event_interruptible_timeout() instead of open-coding similar
behaviour which is subject to the spurious failure described above.

1b2525c05b Bluetooth: btbcm: Stop using upper nibble of rev to chose between uart/USB paths
btbcm_setup_patchram() was using the upper nibble of the revision code to
determine if we are dealing with an uart or USB connected bcm-bt device,
but just as btbcm_initialize() has started accepting 1 and 2 as uart
connected devices, I've now encountered an USB connected device (0a5c:216c)
which has 0 in the upper nibble. So it seems that the upper nibble is not
really a reliable indicator of the bus type.

Instead check hdev->bus which does give us a reliable indication. This
fixes the patchram code trying to load the patchram by the fallback BCM.hcd
filename, now it correctly requests BCM43142A0-0a5c-216c.hcd.

e6ba8208a4 Bluetooth: hci_bcm: Remove irq-active-low DMI quirk for the Thinkpad 8
Interrupts specified through an "Interrupt" ACPI resource (versus through
a "GpioInt" resource) are now always assumed to be active low.

When this change was originally made the Thinkpad 8 quirk was kept around
because it was uncertain if the Thinkpad 8 uses an "Interrupt" or a
"GpioInt" resource.

Bug https://bugzilla.kernel.org/show_bug.cgi?id=196701 has a DSDT for the
Thinkpad 8 attached and it uses an "Interrupt" resource, so the quirk is
not necessary and the quirk, as well as the irq-active-low quirk handling
code can be removed.

2b05393b06 Bluetooth: hci_bcm: Add broken-irq dmi blacklist and add Meegopad T08 to it
The Meegopad T08 hdmi-stick (think Intel computestick) has a brcm43430
wifi/bt combo chip. The BCM2E90 ACPI device describing the BT part does
contain a valid ActiveLow GpioInt entry, but the GPIO it points to never
goes low, so either the IRQ pin is not connected, or the ACPI resource-
table points to the wrong GPIO.

Eitherway things will not work if we try to use the specified IRQ, this
commits adds a DMI based broken-irq blacklist and disables use of the IRQ
and thus also runtime-pm for devices on this list.

This blacklist starts with the the Meegopad T08, fixing bluetooth not
working on this hdmi-stick. Since this is not a battery powered device
the loss of runtime-pm is not really an issue.

Use the flow cookie to ignore attempts to add such flows, we can't

655dc3d2b9 net/mlx5e: Use shared table for offloaded TC eswitch flows
Currently, each representor netdev use their own hash table to keep
the mapping from TC flow (f->cookie) to the driver offloaded instance.
The table is the one which originally was added for offloading TC NIC
(not eswitch) rules.

This scheme breaks when the core TC code calls us to add the same flow
twice, (e.g under egdev use case) since we don't spot that and offload
a 2nd flow into the HW with the wrong source vport.

As a pre-step to solve that, we move to use a single table which keeps
all offloaded TC eswitch flows. The table is located at the eswitch
uplink representor object.

mlx5-updates-2018-05-17

mlx5 core dirver updates for both net-next and rdma-next branches.

From Christophe JAILLET, first three patches to use kvfree where needed.

From: Or Gerlitz <ogerlitz@mellanox.com>

Next six patches from Roi and Co adds support for merged
sriov e-switch which comes to serve cases where both PFs, VFs set
on them and both uplinks are to be used in single v-switch SW model.
When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.

This model allows to offload TC eswitch rules between VFs belonging
to different PFs (and hence have different eswitch affinity), it also

3e99df8772 net/mlx5: Add source e-switch owner
The source e-switch owner allows a vport on one e-switch port be associated
with a rule defined on the second port e-switch.

The role of the source eswitch owner valid bit in the flow group is to
allow the firmware fail driver attempts to wild card the source eswitch
match field. If this bit is not set, the firmware ignores the source
eswitch owner field totally.

a6d0456912 net/mlx5: Add merged e-switch cap
When merged e-switch is supported, the per-port e-switch is logically
merged into one e-switch that spans both physical ports and all the VFs.
Under merged eswitch, both the matching on source vport and setting
destination vport can have a 2nd attribute which is the vhca id of the
eswitch owner.

For example:
esw0: {match: <src vport=1 owner=0> action: fwd to <dst vport=7, owner=1>}
is a flow set on eswitch0 matching on source vport=1 from his eswitch
and the action being fwd to dest vport=7 of eswitch1.

Florian Fainelli says:

====================
net: Allow more drivers with COMPILE_TEST

This patch series includes more drivers to be build tested with COMPILE_TEST
enabled. This helps cover some of the issues I just ran into with missing
a driver *sigh*.

Chanves in v3:

- drop the TI Keystone NETCP driver from the COMPILE_TEST additions

Changes in v2:

- allow FEC to build outside of CONFIG_ARM/ARM64 by defining a layout of
  registers, this is not meant to run, so this is not a real issue if we
  are not matching the correct register layout

8a8633978b qede: Add build_skb() support.
This patch makes use of build_skb() throughout in driver's receieve
data path [HW gro flow and non HW gro flow]. With this, driver can
build skb directly from the page segments which are already mapped
to the hardware instead of allocating new SKB via netdev_alloc_skb()
and memcpy the data which is quite costly.

This really improves performance (keeping same or slight gain in rx
throughput) in terms of CPU utilization which is significantly reduced
[almost half] in non HW gro flow where for every incoming MTU sized
packet driver had to allocate skb, memcpy headers etc. Additionally
in that flow, it also gets rid of bunch of additional overheads
[eth_get_headlen() etc.] to split headers and data in the skb.

Tested with:
system: 2 sockets, 4 cores per socket, hyperthreading, 2x4x2=16 cores
iperf [server]: iperf -s
iperf [client]: iperf -c <server_ip> -t 500 -i 10 -P 32

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2018-05-17

This series contains updates to ixgbe, ixgbevf and ice drivers.

Cathy Zhou resolves sparse warnings by using the force attribute.

Mauro S M Rodrigues fixes a bug where IRQs were not freed if a PCI error
recovery system opts to remove the device which causes
ixgbe_io_error_detected() to return PCI_ERS_RESULT_DISCONNECT before
calling ixgbe_close_suspend() which results in IRQs not freed and
crashing when the remove handler calls pci_disable_device().  Resolved
this by calling ixgbe_close_suspend() before evaluating the PCI channel
state.

Pavel Tatashin releases the rtnl_lock during the call to
ixgbe_close_suspend() to allow scaling if device_shutdown() is
multi-threaded.

Emil modifies ixgbe to not validate the MAC address during a reset,
unless the MAC was set on the host so that the VF will get a new MAC
address every time it reloads.  Also updates ixgbevf to set
hw->mac.perm_addr in order to retain the custom MAC on a reset.

Anirudh updates the ice NVM read/erase/update AQ commands to align with
the latest specification.

990a9d4975 net/ncsi: prevent a couple array underflows
We recently refactored this code and introduced a static checker
warning.  Smatch complains that if cmd->index is zero then we would
underflow the arrays.  That's obviously true.

The question is whether we prevent cmd->index from being zero at a
different level.  I've looked at the code and I don't immediately see
a check for that.

  int val = 1;

  listen(fd, 0);
  shutdown(fd, SHUT_RDWR);
  setsockopt(fd, 6, TCP_NODELAY, &val, 4);
}

Simply initialize conn.tx_work & conn.send_lock at socket creation,
rather than deeper in the stack.
