+
+Add support for calculating the Rx timestamp for HE frames.
+Since now all frame types are supported, allow setting the Rx

+Subject: [PATCH] mac80211: fix time-is-after bug in mlme
+
+The incorrect timeout check caused probing to happen when it did
+not need to happen.  This in turn caused tx performance drop
+for around 5 seconds in ath10k-ct driver.  Possibly that tx drop
+is due to a secondary issue, but fixing the probe to not happen
+when traffic is running fixes the symptom.

+Subject: [PATCH] netfilter: flowtable: separate replace, destroy and
+ stats to different workqueues
+
+Currently the flow table offload replace, destroy and stats work items are
+executed on a single workqueue. As such, DESTROY and STATS commands may
+be backloged after a burst of REPLACE work items. This scenario can bloat
+up memory and may cause active connections to age.
+
+Instatiate add, del and stats workqueues to avoid backlogs of non-dependent
+actions. Provide sysfs control over the workqueue attributes, allowing
+userspace applications to control the workqueue cpumask.

 Subject: [PATCH] netfilter: flowtable: add vlan support
 
 Add the vlan id and protocol to the flow tuple to uniquely identify
 flows from the receive path. For the transmit path, dev_hard_header() on
 the vlan device push the headers. This patch includes support for two
-VLAN headers (QinQ) from the ingress path.
+vlan headers (QinQ) from the ingress path.
+
+Add a generic encap field to the flowtable entry which stores the
+protocol and the tag id. This allows to reuse these fields in the PPPoE
+support coming in a later patch.

+ Netfilter's flowtable infrastructure
+ ====================================
+ 
+-This documentation describes the software flowtable infrastructure available in
+-Netfilter since Linux kernel 4.16.
++This documentation describes the Netfilter flowtable infrastructure which allows
++you to define a fastpath through the flowtable datapath. This infrastructure
++also provides hardware offload support. The flowtable supports for the layer 3
++IPv4 and IPv6 and the layer 4 TCP and UDP protocols.
+ 
+ Overview
+ --------
+ 
+-Initial packets follow the classic forwarding path, once the flow enters the
+-established state according to the conntrack semantics (ie. we have seen traffic
+-in both directions), then you can decide to offload the flow to the flowtable
+-from the forward chain via the 'flow offload' action available in nftables.
+-
+-Packets that find an entry in the flowtable (ie. flowtable hit) are sent to the
+-output netdevice via neigh_xmit(), hence, they bypass the classic forwarding
+-path (the visible effect is that you do not see these packets from any of the
+-netfilter hooks coming after the ingress). In case of flowtable miss, the packet
+-follows the classic forward path.
+-
+-The flowtable uses a resizable hashtable, lookups are based on the following
+-7-tuple selectors: source, destination, layer 3 and layer 4 protocols, source
+-and destination ports and the input interface (useful in case there are several
+-conntrack zones in place).
+-
+-Flowtables are populated via the 'flow offload' nftables action, so the user can
+-selectively specify what flows are placed into the flow table. Hence, packets
+-follow the classic forwarding path unless the user explicitly instruct packets
+-to use this new alternative forwarding path via nftables policy.
++Once the first packet of the flow successfully goes through the IP forwarding
++path, from the second packet on, you might decide to offload the flow to the
++flowtable through your ruleset. The flowtable infrastructure provides a rule
++action that allows you to specify when to add a flow to the flowtable.
++
++A packet that finds a matching entry in the flowtable (ie. flowtable hit) is
++transmitted to the output netdevice via neigh_xmit(), hence, packets bypass the
++classic IP forwarding path (the visible effect is that you do not see these
++packets from any of the Netfilter hooks coming after ingress). In case that
++there is no matching entry in the flowtable (ie. flowtable miss), the packet
++follows the classic IP forwarding path.
++
++The flowtable uses a resizable hashtable. Lookups are based on the following
++n-tuple selectors: layer 2 protocol encapsulation (VLAN and PPPoE), layer 3
++source and destination, layer 4 source and destination ports and the input
++interface (useful in case there are several conntrack zones in place).
++
++The 'flow add' action allows you to populate the flowtable, the user selectively
++specifies what flows are placed into the flowtable. Hence, packets follow the
++classic IP forwarding path unless the user explicitly instruct flows to use this
++new alternative forwarding path via policy.
+ 
+-This is represented in Fig.1, which describes the classic forwarding path
+-including the Netfilter hooks and the flowtable fastpath bypass.

+-path given that the transport selectors are missing, therefore flowtable lookup

++
++Layer 2 encapsulation
++---------------------
++
++Since Linux kernel 5.13, the flowtable infrastructure discovers the real
++netdevice behind VLAN and PPPoE netdevices. The flowtable software datapath
++parses the VLAN and PPPoE layer 2 headers to extract the ethertype and the
++VLAN ID / PPPoE session ID which are used for the flowtable lookups. The
++flowtable datapath also deals with layer 2 decapsulation.
++
++You do not need to add the PPPoE and the VLAN devices to your flowtable,
++instead the real device is sufficient for the flowtable to track your flows.
++
++Bridge and IP forwarding
++------------------------
++
++Since Linux kernel 5.13, you can add bridge ports to the flowtable. The
++flowtable infrastructure discovers the topology behind the bridge device. This
++allows the flowtable to define a fastpath bypass between the bridge ports
++(represented as eth1 and eth2 in the example figure below) and the gateway
++device (represented as eth0) in your switch/router.
++
++::
++                      fastpath bypass
++               .-------------------------.
++              /                           \
++              |           IP forwarding   |
++              |          /             \ \/
++              |       br0               eth0 ..... eth0
++              .       / \                          *host B*
++               -> eth1  eth2
++                   .           *switch/router*
++                   .
++                   .
++                 eth0
++               *host A*
++
++The flowtable infrastructure also supports for bridge VLAN filtering actions
++such as PVID and untagged. You can also stack a classic VLAN device on top of
++your bridge port.
++
++If you would like that your flowtable defines a fastpath between your bridge
++ports and your IP forwarding path, you have to add your bridge ports (as
++represented by the real netdevice) to your flowtable definition.
++
++Counters
++--------
++
++The flowtable can synchronize packet and byte counters with the existing
++connection tracking entry by specifying the counter statement in your flowtable
++definition, e.g.
++
++::
++	table inet x {
++		flowtable f {
++			hook ingress priority 0; devices = { eth0, eth1 };
++			counter
++		}
++		...
++	}
++
++Counter support is available since Linux kernel 5.7.
++
++Hardware offload
++----------------
++
++If your network device provides hardware offload support, you can turn it on by
++means of the 'offload' flag in your flowtable definition, e.g.
++
++::
++	table inet x {
++		flowtable f {
++			hook ingress priority 0; devices = { eth0, eth1 };
++			flags offload;
++		}
++		...
++	}
++
++There is a workqueue that adds the flows to the hardware. Note that a few
++packets might still run over the flowtable software path until the workqueue has
++a chance to offload the flow to the network device.
++
++You can identify hardware offloaded flows through the [HW_OFFLOAD] tag when
++listing your connection tracking table. Please, note that the [OFFLOAD] tag
++refers to the software offload mode, so there is a distinction between [OFFLOAD]
++which refers to the software flowtable fastpath and [HW_OFFLOAD] which refers
++to the hardware offload datapath being used by the flow.
++
++The flowtable hardware offload infrastructure also supports for the DSA
++(Distributed Switch Architecture).
++
++Limitations
++-----------
++
++The flowtable behaves like a cache. The flowtable entries might get stale if
++either the destination MAC address or the egress netdevice that is used for
++transmission changes.
++
++This might be a problem if:
++
++- You run the flowtable in software mode and you combine bridge and IP
++  forwarding in your setup.
++- Hardware offload is enabled.
