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

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.

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)

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.

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.

Currently an if condition is used to select the correct callback to set
rx_onwer in descriptor. Lets keep this simple and always use the same
callback.

We either have .enable_dma_transmission or .set_tx_tail_ptr in the HW
table callbacks, we can never have both so there is no need to check for
GMAC version.

Instead of relying on the GMAC version for choosing if we need to use
dma_init or dma_init_{rx/tx}_chan callback, lets uniformize this and
always use the dma_init_{rx/tx}_chan callbacks.
While at it, fix the use of dma_init_chan callback, which shall be
called for as many channels as the max of rx/tx channels.

PTP and MMC modules base address can depend on the GMAC version. As this
is HW specific lets move this base address calculation to hwif.c. Also,
add an entry in the HW table so that we can specify the module offset.
This can later be extended to more modules, if deemed necessary.

This is cutting down performance. Once the timer is armed it should run
after the time expires for the first packet sent and not the last one.
After this change, running iperf, the performance gain is +/- 24%.

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:

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.

There are some controllers sending out advertising data with illegal
length value which is longer than HCI_MAX_AD_LENGTH, causing the
buffer last_adv_data overflows. To avoid these controllers from
