Pull rdma updates from Jason Gunthorpe:
 "This is quite a small cycle, if not for Lee's 70 patches cleaning the
  kdocs it would be well below typical for patch count.

  Most of the interesting work here was in the HNS and rxe drivers which
  got fairly major internal changes.

  Summary:

   - Driver updates and bug fixes: siw, hns, bnxt_re, mlx5, efa

   - Significant rework in rxe to get it ready to have XRC support added

   - Several rts bug fixes

   - Big series to get to 'make W=1' cleanness, primarily updating kdocs

   - Support for creating a RDMA MR from a DMABUF fd to allow PCI peer
     to peer transfers to GPU VRAM

   - Device disassociation now works properly with umad

10e2ec8ede sound updates for 5.12
A relatively calm release at this time, and no massive code changes
 are found in the stats, while a wide range of code refactoring and
 cleanup have been done.
 
 Note that this update includes the tree-wide trivial changes for
 dropping the return value from ISA remove callbacks, too.
 
 Below lists up some highlight:
 
 * ALSA Core:
 - Support for the software jack injection via debugfs
 - Fixes for sync_stop PCM operations
 
 * HD-audio and USB-audio:
 - A few usual HD-audio device quirks
 - Updates for Tegra HD-audio
 - More quirks for Pioneer and other USB-audio devices
 - Stricter state checks at USB-audio disconnection
 
 * ASoC:
 - Continued code refactoring, cleanup and fixes in ASoC core API
 - A KUnit testsuite for the topology code
 - Lots of ASoC Intel driver Realtek codec updates, quirk additions and
   fixes
 - Support for Ingenic JZ4760(B), Intel AlderLake-P, DT configured
   nVidia cards, Qualcomm lpass-rx-macro and lpass-tx-macro
 - Removal of obsolete SIRF prima/atlas, Txx9 and ZTE zx drivers
 
 * Others:
 - Drop return value from ISA driver remove callback
 - Cleanup with DIV_ROUND_UP() macro
 - FireWire updates, HDSP output loopback support

On cpu architectures w/o dma cache snooping, dma_unmap() is a

a8db76d40e lan743x: boost performance on cpu archs w/o dma cache snooping
The buffers in the lan743x driver's receive ring are always 9K,
even when the largest packet that can be received (the mtu) is
much smaller. This performs particularly badly on cpu archs
without dma cache snooping (such as ARM): each received packet
results in a 9K dma_{map|unmap} operation, which is very expensive
because cpu caches need to be invalidated.

Careful measurement of the driver rx path on armv7 reveals that
the cpu spends the majority of its time waiting for cache
invalidation.

Optimize by keeping the rx ring buffer size as close as possible
to the mtu. This limits the amount of cache that requires
invalidation.

This optimization would normally force us to re-allocate all
ring buffers when the mtu is changed - a disruptive event,
because it can only happen when the network interface is down.

Remove the need to re-allocate all ring buffers by adding support
for multi-buffer frames. Now any combination of mtu and ring
buffer size will work. When the mtu changes from mtu1 to mtu2,
consumed buffers of size mtu1 are lazily replaced by newly
allocated buffers of size mtu2.

These optimizations double the rx performance on armv7.
Third parties report 3x rx speedup on armv8.

Tested with iperf3 on a freescale imx6qp + lan7430, both sides
set to mtu 1500 bytes, measure rx performance:

3af409ca27 net: enetc: fix destroyed phylink dereference during unbind
The following call path suggests that calling unregister_netdev on an
interface that is up will first bring it down.

enetc_pf_remove
-> unregister_netdev
   -> unregister_netdevice_queue
      -> unregister_netdevice_many
         -> dev_close_many
            -> __dev_close_many
               -> enetc_close
                  -> enetc_stop
                     -> phylink_stop

However, enetc first destroys the phylink instance, then calls
unregister_netdev. This is already dissimilar to the setup (and error
path teardown path) from enetc_pf_probe, but more than that, it is buggy
because it is invalid to call phylink_stop after phylink_destroy.

So let's first unregister the netdev (and let the .ndo_stop events
consume themselves), then destroy the phylink instance, then free the
netdev.

- it doesn't support Interconnect roles.
- it supports only a single ring.
- the HW should be able to do forwarding of MRP Test frames so the SW

Normally, auto negotiation and reconnect should be automatically done by

to be restarted manually. This happens because of link training and so
even though still connected to the partner the link never "comes back".
This needs an auto-negotiation restart.

Also, a change in xgbe-mdio is needed to get ethtool to recognize the

30b7edc82e net: amd-xgbe: Reset the PHY rx data path when mailbox command timeout
Sometimes mailbox commands timeout when the RX data path becomes
unresponsive. This prevents the submission of new mailbox commands to DXIO.
This patch identifies the timeout and resets the RX data path so that the
next message can be submitted properly.

ca0d7fd0a5 net: phy: mscc: coma mode disabled for VSC8514
The 'coma mode' (configurable through sw or hw) provides an
optional feature that may be used to control when the PHYs become active.
The typical usage is to synchronize the link-up time across
all PHY instances. This patch releases coma mode if not done by hardware,
otherwise the phys will not link-up.

85e97f0b98 net: phy: mscc: improved serdes calibration applied to VSC8514
The current IB serdes calibration algorithm (performed by the onboard 8051)
has proven to be unstable for the VSC8514 QSGMII phy.
A new algorithm has been developed based on
'Frequency-offset Jittered-Injection' or 'FoJi' method which solves
all known issues.  This patch disables the 8051 algorithm and
replaces it with the new FoJi algorithm.
The calibration is now performed in a new file (mscc_serdes.c),
which can act as an placeholder for future serdes configurations.

3cc2c646be net: phy: mscc: adding LCPLL reset to VSC8514
At Power-On Reset, transients may cause the LCPLL to lock onto a
clock that is momentarily unstable. This is normally seen in QSGMII
setups where the higher speed 6G SerDes is being used.
This patch adds an initial LCPLL Reset to the PHY (first instance)
to avoid this issue.

432119de33 net/mlx5: Add cyc2time HW translation mode support
Device timestamp can be in real time mode (cycles to time translation is
offloaded into the Hardware). With real time mode, HW provides timestamp
which is already translated into nanoseconds.

With this mode, driver adjusts both the HW and timecounter (to keep
clock_info_page updated) using callbacks: adjfreq, adjtime and settime.
HW clock modifications are done via MTUTC access reg commands. Driver is
allowed to modify HW real time clock only if MCAM ptpcyc2realtime_modify
capability is set.

Add MTUTC set function to be used for configuring the HW real time
clock. Modify existing code to support both internal timer (with
conversion via timecounter_cyc2time() and real time (no conversions).

Align the signatures of the helpers converting from timestamp to
nanoseconds. With that, when allocating a queue assign the corresponding
callback with respect to the capability.

Adjust 1PPS timestamp calculation flows based on the timestamp mode.

Cyc2time offload brings two major advantages:
- Improve MTAE (Max Time Absolute Error) for HW TS by up to 160 ns over a
  100% loaded CPU.
- Faster data-path timestamp to nanoseconds, as translation is
  lock-less and done in HW.

On real time mode, timestamp format is 32 high bits of seconds and 32
low bits of nanoseconds. On some flows, driver shall convert this format
into nanoseconds wall-clock with REAL_TIME_TO_NS macro.

HW supports a single clock, and it is shared by all functions on a
device. In case real time clock is used, it is recommended to use
a single GM to all device's functions.

de19cd6cc9 net/mlx5: Move some PPS logic into helper functions
Some of PPS logic (timestamp calculations) fits only internal timer
timestamp mode. Move these logics into helper functions. Later in the
patchset cyc2time HW translation mode will expose its own PPS timestamp
calculations.

With this change, main flow will only hold calling PPS logic based on run
time mode.

7f7ccdea8c net: dsa: sja1105: fix leakage of flooded frames outside bridging domain
Quite embarrasingly, I managed to fool myself into thinking that the
flooding domain of sja1105 source ports is restricted by the forwarding
domain, which it isn't. Frames which match an FDB entry are forwarded
towards that entry's DESTPORTS restricted by REACH_PORT[SRC_PORT], while
frames that don't match any FDB entry are forwarded towards
FL_DOMAIN[SRC_PORT] or BC_DOMAIN[SRC_PORT].

This means we can't get away with doing the simple thing, and we must
manage the flooding domain ourselves such that it is restricted by the
forwarding domain. This new function must be called from the
.port_bridge_join and .port_bridge_leave methods too, not just from
.port_bridge_flags as we did before.
