This patch moves the global link group list to smc_core where the link
group functions are. To make this work, it moves code in af_smc and
smc_ib that operates on the link group list to smc_core as well.
While at it, the link group counter is integrated into the list
structure and initialized to zero.

In addition to the buffer references, SMC currently stores the sizes of
the receive and send buffers in each connection as separate variables.
This patch introduces a buffer length variable in the common buffer
descriptor and uses this length instead.

mlx5e-updates-2018-05-17
From: Or Gerlitz <[email protected]>
This series addresses a regression introduced by the
shared block TC changes [1]. Currently, for VF->VF and uplink->VF rules, the
TC core (cls_api) attempts to offload the same flow multiple times into
the driver, as a side effect of the mlx5 registration to the egdev callback.
We use the flow cookie to ignore attempts to add such flows, we can't
reject them (return error), b/c this will fail the offload attempt, so we
ignore that.
The last patch of the series deals with exposing HW stats counters through
ethtool for the vport reps.
Dave - the regression that we are addressing was introduced in 4.15 [1] and applies
to nfp and mlx5. Jiri suggested to push driver side fixes to net-next, this is
already done for nfp [2][3]. Once this is upstream, we will submit a small/point
single patch fix for the TC core code which can serve for net and stable, but not
carried into net-next, b/c it might limit some future use-cases.

From: Or Gerlitz <[email protected]>
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
sets the some of the foundations needed for uplink LAG support.

tcp: implement SACK compression
When TCP receives an out-of-order packet, it immediately sends
a SACK packet, generating network load but also forcing the
receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.
Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.
This patch series adds SACK compression, but the infrastructure
could be leveraged to also compress ACK in the future.
v2: Addressed Neal feedback.
Added two sysctls to allow fine tuning, or even disabling the feature.
v3: take rtt = min(srtt, rcv_rtt) as Yuchung suggested, because rcv_rtt
can be over estimated for RPC (or sender limited)

When TCP receives an out-of-order packet, it immediately sends

receiver to send 1-MSS pathological packets, increasing its
RTX queue length/depth, and thus processing time.
Wifi networks suffer from this aggressive behavior, but generally
speaking, all these SACK packets add fuel to the fire when networks
are under congestion.
This patch adds a high resolution timer and tp->compressed_ack counter.
Instead of sending a SACK, we program this timer with a small delay,
based on RTT and capped to 1 ms :
delay = min ( 5 % of RTT, 1 ms)
If subsequent SACKs need to be sent while the timer has not yet
expired, we simply increment tp->compressed_ack.
When timer expires, a SACK is sent with the latest information.
Whenever an ACK is sent (if data is sent, or if in-order
data is received) timer is canceled.
Note that tcp_sack_new_ofo_skb() is able to force a SACK to be sent
if the sack blocks need to be shuffled, even if the timer has not
expired.
A new SNMP counter is added in the following patch.
Two other patches add sysctls to allow changing the 1,000,000 and 44
values that this commit hard-coded.

As explained in commit 9f9843a751d0 ("tcp: properly handle stretch
acks in slow start"), TCP stacks have to consider how many packets
are acknowledged in one single ACK, because of GRO, but also
because of ACK compression or losses.
We plan to add SACK compression in the following patch, we
must therefore not call tcp_enter_quickack_mode()

net: stmmac: Clean-up and tune-up
This targets to uniformize the handling of the different GMAC versions in
stmmac_main.c file and also tune-up the HW.
Currently there are some if/else conditions in the main source file which
calls different callbacks depending on the ID of GMAC.
With the introducion of a generic HW interface handling which automatically
selects the GMAC callbacks to be used, it is now unpleasant to see if
conditions in the main code because this should be completely agnostic of the
GMAC version.
This series removes most of these conditions. There are some if conditions
that remain untouched but the callbacks handling are now uniformized.
Tested in GMAC5, hope I didn't break any previous versions.
Please check [1] for performance analisys of patches 3-12.

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 function allows to send a HCI command without expecting any
controller event/response in return. This is allowed for vendor-
specific commands only.

When both CONFIG_BT_HCIUART_INTEL and CONFIG_BT_HCIUART_BCM are not
selected, sparse complains like this:
drivers/bluetooth/hci_ldisc.c:437:9: warning: switch with no cases
Fix the sparse warning by proving a default switch case.

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.
