Pull I3C updates from Alexandre Belloni:
 "A new driver this cycle, for the AMD AXI I3C controller.

  There are also new features such as IBI wakeup support, SETAASA device
  discovery and ACPI support for the the DAA methods, meaning we can now
  communicate with the SPD devices on DDR5 modules.

  New driver:
   - AMD AXI I3C master controller

  Subsystem:
   - I3C Common Command Code (CCC) handling improvements, especially
     around GET CCCs
   - SETAASA device discovery support
   - ACPI support for all existing DAA methods like SETDASA, SETNEWDA as
     well as I2C devices on I3C bus
   - IBI-based wakeup support

  Drivers:
   - dw: SETAASA support
   - mipi-i3c-hci: advertise IBI wakeup capability, AMD_PT I3C
     controller support, PIO queue management support for HCI v1.2
   - renesas: improve suspend to RAM support, add runtime PM support"

+Sample and benchmark scripts for pktgen (packet generator)
+==========================================================
+This directory contains some pktgen sample and benchmark scripts, that
+can easily be copied and adjusted for your own use-case.
+
+General doc is located in kernel: Documentation/networking/pktgen.rst
+
+Helper include files
+====================
+This directory contains two helper shell files, that can be "included"
+by shell source'ing.  Namely "functions.sh" and "parameters.sh".
+
+Common parameters
+-----------------
+The parameters.sh file support easy and consistant parameter parsing
+across the sample scripts.  Usage example is printed on errors::
+
+ Usage: ./pktgen_sample01_simple.sh [-vx] -i ethX
+  -i : ($DEV)       output interface/device (required)
+  -s : ($PKT_SIZE)  packet size
+  -d : ($DEST_IP)   destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
+  -m : ($DST_MAC)   destination MAC-addr
+  -p : ($DST_PORT)  destination PORT range (e.g. 433-444) is also allowed
+  -t : ($THREADS)   threads to start
+  -f : ($F_THREAD)  index of first thread (zero indexed CPU number)
+  -c : ($SKB_CLONE) SKB clones send before alloc new SKB
+  -n : ($COUNT)     num messages to send per thread, 0 means indefinitely
+  -b : ($BURST)     HW level bursting of SKBs
+  -v : ($VERBOSE)   verbose
+  -x : ($DEBUG)     debug
+  -6 : ($IP6)       IPv6
+  -w : ($DELAY)     Tx Delay value (ns)
+  -a : ($APPEND)    Script will not reset generator's state, but will append its config
+
+The global variable being set is also listed.  E.g. the required
+interface/device parameter "-i" sets variable $DEV.
+
+"-a" parameter may be used to create different flows simultaneously.
+In this mode script will keep the existing config, will append its settings.
+In this mode you'll have to manually run traffic with "pg_ctrl start".
+
+For example you may use:
+
+    source ./samples/pktgen/functions.sh
+    pg_ctrl reset
+    # add first device
+    ./pktgen_sample06_numa_awared_queue_irq_affinity.sh -a -i ens1f0 -m 34:80:0d:a3:fc:c9 -t 8
+    # add second device
+    ./pktgen_sample06_numa_awared_queue_irq_affinity.sh -a -i ens1f1 -m 34:80:0d:a3:fc:c9 -t 8
+    # run joint traffic on two devs
+    pg_ctrl start
+
+Common functions
+----------------
+The functions.sh file provides; Three different shell functions for
+configuring the different components of pktgen: pg_ctrl(), pg_thread()
+and pg_set().
+
+These 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
+
+See sample scripts for usage examples.
