For tcindex filter, it is too late to initialize the
net pointer in tcf_exts_validate(), as tcf_exts_get_net()
requires a non-NULL net pointer. We can just move its
initialization into tcf_exts_init(), which just requires
an additional parameter.
This makes the code in tcindex_alloc_perfect_hash()
prettier.

c72219b75f introduced tpacket_set_protocol that parses the Ethernet L2
header and sets skb->protocol if it's unset. It is no longer needed
since the introduction of packet_parse_headers. In case of SOCK_RAW and
unset skb->protocol, packet_parse_headers asks the driver to tell the
protocol number, and it's implemented for all Ethernet devices. As the
old function supported only Ethernet, no functionality is lost.

If the socket was created with socket(AF_PACKET, SOCK_RAW, 0),
skb->protocol will be unset, __skb_flow_dissect() will fail, and
skb_probe_transport_header() will fall back to the offset_hint, making
the resulting skb_transport_offset incorrect.
If, however, there is no transport header in the packet,
transport_header shouldn't be set to an arbitrary value.
Fix it by leaving the transport offset unset if it couldn't be found, to
be explicit rather than to fill it with some wrong value. It changes the
behavior, but if some code relied on the old behavior, it would be
broken anyway, as the old one is incorrect.

====================
This time we have, of note:
* the massive patch series for multi-BSSID support, I ended up
applying that through a side branch to record some details
* CSA improvements
* HE (802.11ax) updates to Draft 3.3
* strongly typed element iteration/etc. to make such code more
readable - this came up in particular in multi-BSSID
* rhashtable conversion patches from Herbert
Along, as usual, with various fixes and improvements.

In order to properly support VLAN filtering being enabled/disabled on a
bridge, while having other ports being non bridge port members, we need
to support the ndo_vlan_rx_{add,kill}_vid callbacks in order to make
sure the non-bridge ports can continue receiving VLAN tags, even when
the switch is globally configured to do ingress/egress VID checking.
Since we can call dsa_port_vlan_{add,del} with a bridge_dev pointer
NULL, we now need to check that in these two functions.
We specifically deal with two possibly problematic cases:
- creating a bridge VLAN entry while there is an existing VLAN device
claiming that same VID
- creating a VLAN device while there is an existing bridge VLAN entry
with that VID
Those are both resolved with returning -EBUSY back to user-space.

VLAN devices on top of a DSA network device which is already part of a
bridge and with said bridge being VLAN aware should not be allowed to be
enslaved into that bridge. For one, this duplicates functionality
offered by the VLAN aware bridge which supports tagged and untagged VLAN
frames processing and it would make things needlessly complex to e.g.:
propagate FDB/MDB accordingly.

This extends the NL80211_CMD_ASSOCIATE event case to report
NL80211_ATTR_REQ_IE similarly to what is already done with the
NL80211_CMD_CONNECT events if the driver provides this information. In
practice, this adds (Re)Association Request frame information element
reporting to mac80211 drivers for the cases where user space SME is
used.
This provides more information for user space to figure out which
capabilities were negotiated for the association. For example, this can
be used to determine whether HT, VHT, or HE is used.

Switches work by learning the MAC address for each attached station by
monitoring traffic from each station. When a station sends a packet,
the switch records which port the MAC address is connected to.
With IPv4 networking, before communication commences with a neighbour,
an ARP packet is broadcasted to all stations asking for the MAC address
corresponding with the IPv4. The desired station responds with an ARP
reply, and the ARP reply causes the switch to learn which port the
station is connected to.
With IPv6 networking, the situation is rather different. Rather than
broadcasting ARP packets, a "neighbour solicitation" is multicasted
rather than broadcasted. This multicast needs to reach the intended
station in order for the neighbour to be discovered.
Once a neighbour has been discovered, and entered into the sending
stations neighbour cache, communication can restart at a point later
without sending a new neighbour solicitation, even if the entry in
the neighbour cache is marked as stale. This can be after the MAC
address has expired from the forwarding cache of the DSA switch -
when that occurs, there is a long pause in communication.
Our DSA implementation for mv88e6xxx switches disables flooding of
multicast and unicast frames for bridged ports. As per the above
description, this is fine for IPv4 networking, since the broadcasted
ARP queries will be sent to and received by all stations on the same
network. However, this breaks IPv6 very badly - blocking neighbour
solicitations and later causing connections to stall.
The defaults that the Linux bridge code expect from bridges are for
unknown unicast and unknown multicast frames to be flooded to all ports
on the bridge, which is at odds to the defaults adopted by our DSA
implementation for mv88e6xxx switches.
This commit enables by default flooding of both unknown unicast and
unknown multicast frames whenever a port is added to a bridge, and
disables the flooding when a port leaves the bridge. This means that
mv88e6xxx DSA switches now behave as per the bridge(8) man page, and
IPv6 works flawlessly through such a switch.

entries one by one using the MRT_DEL_MFC socket option or to destroy and
recreate the socket.
Create a new socket option which with the use of optional flags can
clear any combination of multicast entries (static or not static) and
multicast vifs (static or not static).
Calling the new socket option MRT_FLUSH with the flags MRT_FLUSH_MFC and

(cherry picked from commit 033b228e7f26b29ae37f8bfa1bc6b209a5365e9f)
When tcindex_destroy() destroys all the filter results in
the perfect hash table, it invokes the walker to delete
each of them. However, results with class==0 are skipped
in either tcindex_walk() or tcindex_delete(), which causes
a memory leak reported by kmemleak.
This patch fixes it by skipping the walker and directly
deleting these filter results so we don't miss any filter
result.
As a result of this change, we have to initialize exts->net
properly in tcindex_alloc_perfect_hash(). For net-next, we
need to consider whether we should initialize ->net in
tcf_exts_init() instead, before that just directly test
CONFIG_NET_CLS_ACT=y.

(cherry picked from commit 8015d93ebd27484418d4952284fd02172fa4b0b2)
tcindex_destroy() invokes tcindex_destroy_element() via
a walker to delete each filter result in its perfect hash
table, and tcindex_destroy_element() calls tcindex_delete()
which schedules tcf RCU works to do the final deletion work.
Unfortunately this races with the RCU callback
__tcindex_destroy(), which could lead to use-after-free as
reported by Adrian.
Fix this by migrating this RCU callback to tcf RCU work too,
as that workqueue is ordered, we will not have use-after-free.
Note, we don't need to hold netns refcnt because we don't call
tcf_exts_destroy() here.

Each tls context maintains two cipher contexts (one each for tx and rx
directions). For each tls session, the constants such as protocol
version, ciphersuite, iv size, associated data size etc are same for
both the directions and need to be stored only once per tls context.
Hence these are moved from 'struct cipher_context' to 'struct

RPS not work for DSA devices since the 'skb_get_hash'
will always get the invalid hash for dsa tagged packets.
"[PATCH] tag_mtk: add flow_dissect callback to the ops struct"

MTK tagged packet. Tag_dsa and tag_edsa also need to implement
the callback.
