In ksz9477.c file, configuring the xmii register is performed based on
the flag NEW_XMII. The flag is reset for ksz9893 switch and set for
other switch. This patch uses the ksz common xmii set and get function.
The bit values are configured based on the chip id.

This patch read the rgmii tx and rx delay from device tree and stored it
in the ksz_port. It applies the rgmii delay to the xmii tune adjust
register based on the interface selected in phylink mac config. There
are two rgmii port in LAN937x and value to be loaded in the register
vary depends on the port selected.

This patch add the common ksz_set_xmii function for ksz series switch
and update the lan937x code phylink mac config. The register address for
the ksz8795 is Port 5 Interface control 6 and for all other switch is
xMII Control 1.
The bit value for selecting the interface is same for
KSZ8795 and KSZ9893 are same. The bit values for KSZ9477 and lan973x are
same. So, this patch add the bit value for each switches in
ksz_chip_data and configure the registers based on the chip id.

This patch add common function for configuring the Full/Half duplex and
transmit/receive flow control. KSZ8795 uses the Global control register
4 for configuring the duplex and flow control, whereas all other KSZ9477

This patch adds the function for configuring the 100/10Mbps speed
selection for the ksz switches. KSZ8795 switch uses Global control 4
register 0x06 bit 4 for choosing 100/10Mpbs. Other switches uses xMII
control 1 0xN300 for it.
For KSZ8795, if the bit is set then 10Mbps is chosen and if bit is
clear then 100Mbps chosen. For all other switches it is other way
around, if the bit is set then 100Mbps is chosen.
So, this patch add the generic function for ksz switch to select the
100/10Mbps speed selection. While configuring, first it disables the
gigabit functionality and then configure the respective speed.

This patch add helper function for setting and getting the gigabit
enable for the ksz series switch. KSZ8795 switch has different register
address compared to all other ksz switches. KSZ8795 series uses the Port
5 Interface control 6 Bit 6 for configuring the 1Gbps or 100/10Mbps
speed selection. All other switches uses the xMII control 1 0xN301
register Bit6 for gigabit.
Further, for KSZ8795 & KSZ9893 switches if bit 1 then 1Gbps is chosen
and if bit 0 then 100/10Mbps is chosen. It is other way around for
other switches bit 0 is for 1Gbps. So, this patch implements the common
function for configuring the gigabit set and get capability.

New subflows are created within the kernel using O_NONBLOCK, so
EINPROGRESS is the expected return value from kernel_connect().
__mptcp_subflow_connect() has the correct logic to consider EINPROGRESS
to be a successful case, but it has also used that error code as its
return value.
Before v5.19 this was benign: all the callers ignored the return
value. Starting in v5.19 there is a MPTCP_PM_CMD_SUBFLOW_CREATE generic
netlink command that does use the return value, so the EINPROGRESS gets
propagated to userspace.
Make __mptcp_subflow_connect() always return 0 on success instead.

netfilter updates for net
Three late fixes for netfilter:
1) If nf_queue user requests packet truncation below size of l3 header,
we corrupt the skb, then crash. Reject such requests.
2) add cond_resched() calls when doing cycle detection in the
nf_tables graph. This avoids softlockup warning with certain
rulesets.
3) Reject rulesets that use nftables 'queue' expression in family/chain
combinations other than those that are supported. Currently the ruleset
will load, but when userspace attempts to reinject you get WARN splat +
packet drops.

Commit 824ddc601adc ("userfaultfd: provide unmasked address on
page-fault") was introduced to fix an old bug, in which the offset in the
address of a page-fault was masked. Concerns were raised - although were
never backed by actual code - that some userspace code might break because
the bug has been around for quite a while. To address these concerns a
new flag was introduced, and only when this flag is set by the user,
userfaultfd provides the exact address of the page-fault.
The commit however had a bug, and if the flag is unset, the offset was
always masked based on a base-page granularity. Yet, for huge-pages, the
behavior prior to the commit was that the address is masked to the
huge-page granulrity.
While there are no reports on real breakage, fix this issue. If the flag
is unset, use the address with the masking that was done before.

tls: rx: decrypt from the TCP queue
This is the final part of my TLS Rx rework. It switches from
strparser to decrypting data from skbs queued in TCP. We don't
need the full strparser for TLS, its needs are very basic.
This set gives us a small but measurable (6%) performance
improvement (continuous stream).

TLS is a relatively poor fit for strparser. We pause the input
every time a message is received, wait for a read which will
decrypt the message, start the parser, repeat. strparser is
built to delineate the messages, wrap them in individual skbs
and let them float off into the stack or a different socket.
TLS wants the data pages and nothing else. There's no need
for TLS to keep cloning (and occasionally skb_unclone()'ing)
the TCP rx queue.
This patch uses a pre-allocated skb and attaches the skbs
from the TCP rx queue to it as frags. TLS is careful never
to modify the input skb without CoW'ing / detaching it first.
Since we call TCP rx queue cleanup directly we also get back
the benefit of skb deferred free.
Overall this results in a 6% gain in my benchmarks.

Wrap the remaining skb_cow_data() into a helper, so it's easier

Expose TCP rx queue accessor and cleanup, so that TLS can
decrypt directly from the TCP queue. The expectation
is that the caller can access the skb returned from
tcp_recv_skb() and up to inq bytes worth of data (some
of which may be in ->next skbs) and then call
tcp_read_done() when data has been consumed.
The socket lock must be held continuously across
those two operations.

The non-zero-copy path assumes a full skb with decrypted contents.
This means the device offload would have to CoW the data. Try
to keep the zero-copy status instead, copy the data to user space.

In the future we'll want to reuse the input skb in case of
zero-copy so we shouldn't always free darg.skb. Move the
freeing of darg.skb into the non-zc cases. All cases will
now free ctx->recv_pkt (inside let tls_rx_rec_done()).

Implement dev info and dev flash for line cards
This patchset implements two features:
1) "devlink dev info" is exposed for line card (patches 6-9)
2) "devlink dev flash" is implemented for line card gearbox
flashing (patch 10)
For every line card, "a nested" auxiliary device is created which
allows to bind the features mentioned above (patch 4).
The relationship between line card and its auxiliary dev devlink
is carried over extra line card netlink attribute (patches 3 and 5).
The first patch removes devlink_mutex from devlink_register/unregister()
which eliminates possible deadlock during devlink reload command. The
second patchset follows up with putting net pointer check into new
helper.

during xarray iteration
Remove dependency on devlink_mutex during devlinks xarray iteration.
The reason is that devlink_register/unregister() functions taking
devlink_mutex would deadlock during devlink reload operation of devlink
instance which registers/unregisters nested devlink instances.
The devlinks xarray consistency is ensured internally by xarray.
There is a reference taken when working with devlink using
devlink_try_get(). But there is no guarantee that devlink pointer
picked during xarray iteration is not freed before devlink_try_get()
is called.
Make sure that devlink_try_get() works with valid pointer.
Achieve it by:
1) Splitting devlink_put() so the completion is sent only
after grace period. Completion unblocks the devlink_unregister()
routine, which is followed-up by devlink_free()
2) During devlinks xa_array iteration, get devlink pointer from xa_array
holding RCU read lock and taking reference using devlink_try_get()
before unlock.

fq_init() from ieee80211_txq_setup_flows() initializes this spinlock.
According to discussion [2], Toke was not happy with expanding usage of

can instead use synchronize_rcu() for flushing ieee80211_wake_txqs().

Tx side sets EOP and RS bits on descriptors to indicate that a
particular descriptor is the last one and needs to generate an irq when
it was sent. These bits should not be checked on completion path
regardless whether it's the Tx or the Rx. DD bit serves this purpose and
it indicates that a particular descriptor is either for Rx or was
successfully Txed. EOF is also set as loopback test does not xmit
fragmented frames.
Look at (DD | EOF) bits setting in ice_lbtest_receive_frames() instead
of EOP and RS pair.

The driver currently does not allow two VSIs in the same PF domain
to have the same unicast MAC address. This is incorrect in the sense
that a policy decision is being made in the driver when it must be
left to the user. This approach was causing issues when rebooting
the system with VFs spawned not being able to change their MAC addresses.
Such errors were present in dmesg:
[ 7921.068237] ice 0000:b6:00.2 ens2f2: Unicast MAC 6a:0d:e4:70:ca:d1 already
exists on this PF. Preventing setting VF 7 unicast MAC address to 6a:0d:e4:70:ca:d1
Fix that by removing this restriction. Doing this also allows
us to remove some additional code that's checking if a unicast MAC
filter already exists.

Fix checksum offload on VXLAN tunnels.
In case, when mpls protocol is not used, set l4 header to transport
header of skb. This fixes case, when user tries to offload checksums
of VXLAN tunneled traffic.
Steps for reproduction (requires link partner with tunnels):
ip l s enp130s0f0 up
ip a f enp130s0f0
ip a a 10.10.110.2/24 dev enp130s0f0
ip l s enp130s0f0 mtu 1600
ip link add vxlan12_sut type vxlan id 12 group 238.168.100.100 dev enp130s0f0 dstport 4789
ip l s vxlan12_sut up
ip a a 20.10.110.2/24 dev vxlan12_sut
iperf3 -c 20.10.110.1 #should connect
Offload params: td_offset, cd_tunnel_params were
corrupted, due to l4 header pointing wrong address. NIC would then drop
those packets internally, due to incorrect TX descriptor data,
which increased GLV_TEPC register.

Legacy VLAN implementation allows for untrusted VF to have 8 VLAN
filters, not counting VLAN 0 filters. Current VLAN_V2 implementation
lowers available filters for VF, by counting in VLAN 0 filter for both
TPIDs.
Fix this by counting only non zero VLAN filters.
Without this patch, untrusted VF would not be able to access 8 VLAN
filters.

Trying to use 'queue' statement in ingress (for example)
triggers a splat on reinject:
WARNING: CPU: 3 PID: 1345 at net/netfilter/nf_queue.c:291
... because nf_reinject cannot find the ruleset head.
The netdev family doesn't support async resume at the moment anyway,
so disallow loading such rulesets with a more appropriate
error message.
v2: add 'validate' callback and also check hook points, v1 did
allow ingress use in 'table inet', but that doesn't work either. (Pablo)

Domingo Dirutigliano and Nicola Guerrera report kernel panic when
sending nf_queue verdict with 1-byte nfta_payload attribute.
The IP/IPv6 stack pulls the IP(v6) header from the packet after the
input hook.
If user truncates the packet below the header size, this skb_pull() will
result in a malformed skb (skb->len < 0).

Add support for creating PPPoE filters in switchdev mode. Add support
for parsing PPPoE and PPP-specific tc options: pppoe_sid and ppp_proto.
Example filter:
tc filter add dev $PF1 ingress protocol ppp_ses prio 1 flower pppoe_sid \
1234 ppp_proto ip skip_sw action mirred egress redirect dev $VF1_PR
Changes in iproute2 are required to use the new fields.
ICE COMMS DDP package is required to create a filter as it contains PPPoE
profiles. Added a warning message when loaded DDP package does not contain
required profiles.
