When code reaches the "out" label, n is guaranteed to be valid so we can
unconditionally call neigh_release.
Also change the label to release_neigh to better reflect the fact that
we unconditionally free the neighbour and also match other labels
convention.

Improve mlx5e_route_lookup_ipv6 function structure by avoiding #ifdef then
return -EOPNOTSUPP in the middle of the function code.
To do so, we stub out mlx5e_tc_tun_create_header_ipv6 which is the only
caller of this helper function to avoid calling it altogether
when ipv6 is compiled out, which should also cleanup some compiler
warnings of unused variables.

Refactor flex parser tunnel code:
- Add definition for flex parser tunneling header for VXLAN-GPE
- Use macros for VXLAN-GPE SW steering when building STE
- Refactor the code to reflect that this is a VXLAN GPE
only code and not a general flex parser code.
This also significantly simplifies addition of more
flex parser protocols, such as Geneve.

The virtchannel interface was repeating a lot of strings
and wasting storage space in the kernel. There was also
inconsistent messages for the same thing. Consolidate all
those messages and bit checks into a couple of helper functions.
Also, reduce stack space usage by simplifying getting the pointer
to the pf using a helper.

Currently ice_clear_vsi_promisc() detects if the VLAN ID sent is not 0
and sets the recipe_id to ICE_SW_LKUP_PROMISC_VLAN in that case and
ICE_SW_LKUP_PROMISC if the VLAN_ID is 0. However this doesn't allow VLAN
0 promiscuous rules to be removed, but they can be added. Fix this by
checking if the promisc_mask contains ICE_PROMISC_VLAN_RX or
ICE_PROMISC_VLAN_TX. This change was made to match what is being done
for ice_set_vsi_promisc().

Currently there can be a case where a DCB map is applied and there are
more interrupt vectors (vsi->num_q_vectors) than Rx queues (vsi->num_rxq)
and Tx queues (vsi->num_txq). If we try to set coalesce settings in this
case it will report a false failure. Fix this by checking if vector index
is valid with respect to the number of Tx and Rx queues configured.

It is wrong to set PF disable state flag for all VFs when freeing VF
resources - Instead, we should set VF disable state flag for each VF with
its resources being returned to the device. Right now, all VF opcodes,
mailbox communication to clear its resources as well fails - since we
already indicate that PF is in disable state, with all VFs not active. In
addition, we don't need to notify VF that PF is intending to reset it, if
it is already in disabled state.

Currently when adding/deleting vlans in ice_vc_process_vlan_msg()
we are calling ice_vsi_manage_vlan_stripping() to enable/disable
when adding and deleting a VLAN respectively. This is wrong
because adding/deleting VLANs has nothing to do with configuring
VLAN stripping. VLAN stripping is configured through the
following VIRTCHNL operations:
VIRTCHNL_OP_ENABLE_VLAN_STRIPPING
VIRTCHNL_OP_DISABLE_VLAN_STRIPPING
Unfortunately we can't just remove this because then stripping
will never be configured on VF initialization. Fix this by
adding a new function that initializes (disables/enables) VLAN
stripping for the VF based on the device supported capabilities.
This allows us to remove the call to
ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().

Currently if the host disables VLAN offloads on the VF by
not setting the VIRTCHNL_VF_OFFLOAD_VLAN capability bit
we will still honor VF VLAN configuration messages over
VIRTCHNL. These messages (i.e. enable/disable VLAN stripping
and VLAN filtering) should be blocked when the feature
is not supported. Fix that by adding a helper function to
determine if the VF is allowed to do VLAN operations based
on the host's VF configuration.
Also, mirror the VF communicated capabilities in the host's
VF configuration.

Call napi_disable() twice would cause dead lock. There are three situations
may result in the issue.
1. rtl8152_pre_reset() and set_carrier() are run at the same time.
2. Call rtl8152_set_tunable() after rtl8152_close().
3. Call rtl8152_set_ringparam() after rtl8152_close().
For #1, use the same solution as commit 84811412464d ("r8152: Re-order

of IFF_UP and using napi_disable/napi_enable during mutex.

End.DT6 behavior makes use of seg6_lookup_nexthop() function which drops
all packets that are destined to be locally processed. However, DT* should
be able to deliver decapsulated packets that are destined to local
addresses. Function seg6_lookup_nexthop() is also used by DX6, so in order
to maintain compatibility I created another routing helper function which
is called seg6_lookup_any_nexthop(). This function is able to take into
account both packets that have to be processed locally and the ones that
are destined to be forwarded directly to another machine. Hence,
seg6_lookup_any_nexthop() is used in DT6 rather than seg6_lookup_nexthop()
to allow local delivery.

In commit a82055af5959 ("netfilter: nft_payload: add VLAN offload
support"), VLAN fields in struct flow_dissector_key_vlan were unionized
with the intention of introducing another field that covered the whole TCI
header. However without a wrapping struct the subfields end up sharing the
same bits. As a result, "tc filter add ... flower vlan_id 14" specifies not
only vlan_id, but also vlan_priority.
Fix by wrapping the individual VLAN fields in a struct.

It is observed that TIPC service binding order will not be kept in the
publication event report to user if the service is subscribed after the
bindings.
For example, services are bound by application in the following order:
Server: bound port A to {18888,66,66} scope 2
Server: bound port A to {18888,33,33} scope 2
Now, if a client subscribes to the service range (e.g. {18888, 0-100}),
it will get the 'TIPC_PUBLISHED' events in that binding order only when
the subscription is started before the bindings.
Otherwise, if started after the bindings, the events will arrive in the
opposite order:
Client: received event for published {18888,33,33}
Client: received event for published {18888,66,66}
For the latter case, it is clear that the bindings have existed in the
name table already, so when reported, the events' order will follow the
order of the rbtree binding nodes (- a node with lesser 'lower'/'upper'
range value will be first).
This is correct as we provide the tracking on a specific service status
(available or not), not the relationship between multiple services.
However, some users expect to see the same order of arriving events
irrespective of when the subscription is issued. This turns out to be
easy to fix. We now add functionality to ensure that publication events
always are issued in the same temporal order as the corresponding
bindings were performed.
v2: replace the unnecessary macro - 'publication_after()' with inline
function.
v3: reuse 'time_after32()' instead of reinventing the same exact code.

Once udp stack has set the UDP_SKB_IS_STATELESS flag, later skb free
assumes all skb head state has been dropped already.
This will leak the extension memory in case the skb has extensions other
than the ipsec secpath, e.g. bridge nf data.
To fix this, set the UDP_SKB_IS_STATELESS flag only if we don't have
extensions or if the extension space can be free'd.

Let's limit shrinking to !ZONE_DEVICE so we can fix the current code.
We should never try to touch the memmap of offline sections where we
could have uninitialized memmaps and could trigger BUGs when calling
page_to_nid() on poisoned pages.
There is no reliable way to distinguish an uninitialized memmap from an
initialized memmap that belongs to ZONE_DEVICE, as we don't have
anything like SECTION_IS_ONLINE we can use similar to
pfn_to_online_section() for !ZONE_DEVICE memory.
E.g., set_zone_contiguous() similarly relies on pfn_to_online_section()
and will therefore never set a ZONE_DEVICE zone consecutive. Stopping
to shrink the ZONE_DEVICE therefore results in no observable changes,
besides /proc/zoneinfo indicating different boundaries - something we
can totally live with.
Before commit d0dc12e86b31 ("mm/memory_hotplug: optimize memory
hotplug"), the memmap was initialized with 0 and the node with the right
value. So the zone might be wrong but not garbage. After that commit,
both the zone and the node will be garbage when touching uninitialized
memmaps.
Toshiki reported a BUG (race between delayed initialization of
ZONE_DEVICE memmaps without holding the memory hotplug lock and
concurrent zone shrinking).

The previous commit added the ability to throttle stations when they queue
too much airtime in the hardware. This commit enables the functionality by
calculating the expected airtime usage of each packet that is dequeued from
the TXQs in mac80211, and accounting that as pending airtime.
The estimated airtime for each skb is stored in the tx_info, so we can
subtract the same amount from the running total when the skb is freed or
recycled. The throttling mechanism relies on this accounting to be
accurate (i.e., that we are not freeing skbs without subtracting any
airtime they were accounted for), so we put the subtraction into
ieee80211_report_used_skb(). As an optimisation, we also subtract the
airtime on regular TX completion, zeroing out the value stored in the
packet afterwards, to avoid having to do an expensive lookup of the station
from the packet data on every packet.
This patch does *not* include any mechanism to wake a throttled TXQ again,
on the assumption that this will happen anyway as a side effect of whatever
freed the skb (most commonly a TX completion).

In order for the Fq_CoDel algorithm integrated in mac80211 layer to operate
effectively to control excessive queueing latency, the CoDel algorithm
requires an accurate measure of how long packets stays in the queue, AKA
sojourn time. The sojourn time measured at the mac80211 layer doesn't
include queueing latency in the lower layer (firmware/hardware) and CoDel
expects lower layer to have a short queue. However, most 802.11ac chipsets
offload tasks such TX aggregation to firmware or hardware, thus have a deep
lower layer queue.
Without a mechanism to control the lower layer queue size, packets only
stay in mac80211 layer transiently before being sent to firmware queue.
As a result, the sojourn time measured by CoDel in the mac80211 layer is
almost always lower than the CoDel latency target, hence CoDel does little
to control the latency, even when the lower layer queue causes excessive
latency.
The Byte Queue Limits (BQL) mechanism is commonly used to address the
similar issue with wired network interface. However, this method cannot be
applied directly to the wireless network interface. "Bytes" is not a
suitable measure of queue depth in the wireless network, as the data rate
can vary dramatically from station to station in the same network, from a
few Mbps to over Gbps.
This patch implements an Airtime-based Queue Limit (AQL) to make CoDel work
effectively with wireless drivers that utilized firmware/hardware
offloading. AQL allows each txq to release just enough packets to the lower
layer to form 1-2 large aggregations to keep hardware fully utilized and
retains the rest of the frames in mac80211 layer to be controlled by the
CoDel algorithm.

Felix recently added code to calculate airtime of packets to the mt76
driver. Import this into mac80211 so we can use it for airtime queue limit
calculations.
The airtime.c file is copied verbatim from the mt76 driver, and adjusted to
be usable in mac80211. This involves:
- Switching to mac80211 data structures.
- Adding support for 160 MHz channels and HE mode.
- Moving the symbol and duration calculations around a bit to avoid
rounding with the higher rates and longer symbol times used for HE rates.
The per-rate TX rate calculation is also split out to its own function so
it can be used directly for the AQL calculations later.

Commit 7b6ddeaf27ec ("mac80211: use QoS NDP for AP probing")
let STAs send QoS Null frames as PS triggers if the AP was
a QoS STA. However, the mac80211 PS stack relies on an
interface flag IEEE80211_STA_NULLFUNC_ACKED for
determining trigger frame ACK, which was not being set for
acked non-QoS Null frames. The effect is an inability to
trigger hardware sleep via IEEE80211_CONF_PS since the QoS
Null frame was seemingly never acked.
This bug only applies to drivers which set both
IEEE80211_HW_REPORTS_TX_ACK_STATUS and
IEEE80211_HW_PS_NULLFUNC_STACK.
Detect the acked QoS Null frame to restore STA power save.
