rtw_hw_queue_mapping() and ac_to_hwq[] hold values of type enum
rtw_tx_queue_type. Change their types to reflect this to make it easier
to understand this part of the code.

While here, also change the array to be static const as it is not
supposed to be modified at runtime.

e6a1c4b988 wifi: libertas: add support for WPS enrollee IE in probe requests
Add compatibility with WPS by passing on WPS enrollee information in
probe requests. Ignore other IEs supplied in the scan request. This also
has the added benefit of restoring compatibility with newer
wpa_supplicant versions that always add scan IEs. Previously, with
max_scan_ie_len set to 0, scans would always fail.

57db1ba357 wifi: libertas: only add RSN/WPA IE in lbs_add_wpa_tlv
The existing code only converts the first IE to a TLV, but it returns a
value that takes the length of all IEs into account. When there is more
than one IE (which happens with modern wpa_supplicant versions for
example), the returned length is too long and extra junk TLVs get sent
to the firmware, resulting in an association failure.

Fix this by finding the first RSN or WPA IE and only adding that. This
has the extra benefit of working properly if the RSN/WPA IE isn't the
first one in the IE buffer.

While we're at it, clean up the code to use the available structs like
the other lbs_add_* functions instead of directly manipulating the TLV
buffer.

33f5d733b5 net: renesas: rswitch: Improve TX timestamp accuracy
In the previous code, TX timestamp accuracy was bad because the irq
handler got the timestamp from the timestamp register at that time.

This hardware has "Timestamp capture" feature which can store
each TX timestamp into the timestamp descriptors. To improve
TX timestamp accuracy, implement timestamp descriptors' handling.

48cf0a2570 net: renesas: rswitch: Remove gptp flag from rswitch_gwca_queue
In the previous code, the gptp flag was completely related to
the !dir_tx in struct rswitch_gwca_queue because
rswitch_gwca_queue_alloc() was called below:

< In rswitch_txdmac_alloc() >
err = rswitch_gwca_queue_alloc(ndev, priv, rdev->tx_queue, true, false,
			      TX_RING_SIZE);
So, dir_tx = true, and gptp = false.

< In rswitch_rxdmac_alloc() >
err = rswitch_gwca_queue_alloc(ndev, priv, rdev->rx_queue, false, true,
			      RX_RING_SIZE);
So, dir_tx = false, and gptp = true.

In the future, a new queue handling for timestamp will be implemented
and this gptp flag is confusable. So, remove the gptp flag.

049139126e selftests: forwarding: Add MDB dump test cases
The kernel maintains three markers for the MDB dump:

1. The last bridge device from which the MDB was dumped.
2. The last MDB entry from which the MDB was dumped.
3. The last port-group entry that was dumped.

Add test cases for large scale MDB dump to make sure that all the
configured entries are dumped and that the markers are used correctly.

Specifically, create 2 bridges with 32 ports and add 256 MDB entries in
which all the ports are member of. Test that each bridge reports 8192
(256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB
entries.

On my system, MDB dump of the above is contained in about 50 netlink
messages.

Example output:

 # ./bridge_mdb.sh
 [...]
 INFO: # Large scale dump tests
 TEST: IPv4 large scale dump tests                                   [ OK ]

eventually be moved to the rtnetlink code.

Use 'NLA_NESTED' for 'MDBA_SET_ENTRY_ATTRS' instead of
NLA_POLICY_NESTED() as this attribute is going to be validated using
different policies in the underlying drivers.

7ea829664d bridge: mcast: Remove pointless sequence generation counter assignment
The purpose of the sequence generation counter in the netlink callback
is to identify if a multipart dump is consistent or not by calling
nl_dump_check_consistent() whenever a message is generated.

The function is not invoked by the MDB code, rendering the sequence
generation counter assignment pointless. Remove it.

Note that even if the function was invoked, we still could not
accurately determine if the dump is consistent or not, as there is no
sequence generation counter for MDB entries, unlike nexthop objects, for
example.

Xin Long says:

====================
net: move more duplicate code of ovs and tc conntrack into nf_conntrack_ovs

We've moved some duplicate code into nf_nat_ovs in:

  "net: eliminate the duplicate code in the ct nat functions of ovs and tc"

This patchset addresses more code duplication in the conntrack of ovs
and tc then creates nf_conntrack_ovs for them, and four functions will
be extracted and moved into it:

  nf_ct_handle_fragments()
  nf_ct_skb_network_trim()
  nf_ct_helper()
  nf_ct_add_helper()

0785407e78 net: extract nf_ct_handle_fragments to nf_conntrack_ovs
Now handle_fragments() in OVS and TC have the similar code, and
this patch removes the duplicate code by moving the function
to nf_conntrack_ovs.

Note that skb_clear_hash(skb) or skb->ignore_df = 1 should be
done only when defrag returns 0, as it does in other places
in kernel.

1b83bf4489 openvswitch: move key and ovs_cb update out of handle_fragments
This patch has no functional changes and just moves key and ovs_cb update
out of handle_fragments, and skb_clear_hash() and skb->ignore_df change
into handle_fragments(), to make it easier to move the duplicate code
from handle_fragments() into nf_conntrack_ovs later.

Note that it changes to pass info->family to handle_fragments() instead
of key for the packet type check, as info->family is set according to
key->eth.type in ovs_ct_copy_action() when creating the action.

Similar to nf_nat_ovs created by Commit ebddb14049 ("net: move the
nat function to nf_nat_ovs for ovs and tc"), this patch is to create
nf_conntrack_ovs to get these functions shared by OVS and TC only.

There are nf_ct_helper() and nf_ct_add_helper() from nf_conntrak_helper
in this patch, and will be more in the following patches.

sanitizers, it's not strictly necessary, but is also helpful.

Memory Sanitizer requires passing different options to CFLAGS and
LDFLAGS: besides the mandatory -fsanitize=memory, one needs to pass
header and library paths, and passing -L to a compilation step
triggers -Wunused-command-line-argument. So introduce a separate
variable for linker flags. Use $(SAN_CFLAGS) as a default in order to
avoid complicating the ASan usage.

025a785ff0 net: skbuff: drop the word head from skb cache
skbuff_head_cache is misnamed (perhaps for historical reasons?)
because it does not hold heads. Head is the buffer which skb->data
points to, and also where shinfo lives. struct sk_buff is a metadata
structure, not the head.

Eric recently added skb_small_head_cache (which allocates actual
head buffers), let that serve as an excuse to finally clean this up :)

Leave the user-space visible name intact, it could possibly be uAPI.

01a7ee36e7 Merge branch 'net-ipa-GSI'
Alex Elder says:

====================
net: ipa: prepare for GSI register updtaes

An upcoming series (or two) will convert the definitions of GSI
registers used by IPA so they use the "IPA reg" mechanism to specify
register offsets and their fields.  This will simplify implementing
the fairly large number of changes required in GSI registers to
support more than 32 GSI channels (introduced in IPA v5.0).

A few minor problems and inconsistencies were found, and they're
fixed here.  The last three patches in this series change the
"ipa_reg" code to separate the IPA-specific part (the base virtual
address, basically) from the generic register part, and the now-
generic code is renamed to use just "reg_" or "REG_" as a prefix
rather than "ipa_reg" or "IPA_REG_".

81772e444d net: ipa: start generalizing "ipa_reg"
IPA register definitions have evolved with each new version.  The
changes required to support more than 32 endpoints in IPA v5.0 made
it best to define a unified mechanism for defining registers and
their fields.

GSI register definitions, meanwhile, have remained fairly stable.
And even as the total number of IPA endpoints goes beyond 32, the
number of GSI channels on a given EE that underly endpoints still
remains 32 or less.

Despite that, GSI v3.0 (which is used with IPA v5.0) extends the
number of channels (and events) it supports to be about 256, and as
a result, many GSI register definitions must change significantly.
To address this, we'll use the same "ipa_reg" mechanism to define
the GSI registers.

As a first step in generalizing the "ipa_reg" to also support GSI
registers, isolate the definitions of the "ipa_reg" and "ipa_regs"
structure types (and some supporting macros) into a new header file,
and remove the "ipa_" and "IPA_" from symbol names.

Separate the IPA register ID validity checking from the generic
check that a register ID is in range.  Aside from that, this is
intended to have no functional effect on the code.

c5ebba75c7 net: ipa: use bitmasks for GSI IRQ values
There are seven GSI interrupt types that can be signaled by a single
GSI IRQ.  These are represented in a bitmask, and the gsi_irq_type_id
enumerated type defines what each bit position represents.

Similarly, the global and general GSI interrupt types each has a set
of conditions it signals, and both types have an enumerated type
that defines which bit that represents each condition.

When used, these enumerated values are passed as an argument to BIT()
in *all* cases.  So clean up the code a little bit by defining the
enumerated type values as one-bit masks rather than bit positions.

Rename gsi_general_id to be gsi_general_irq_id for consistency.
