1c699ffa48 tls: rx: assume crypto always calls our callback
If crypto didn't always invoke our callback for async
we'd not be clearing skb->sk and would crash in the
skb core when freeing it. This if must be dead code.

Async crypto never worked with TLS 1.3 and was explicitly disabled in
commit 8497ded2d1 ("net/tls: Disable async decrytion for tls1.3").
There's no need for us to handle TLS 1.3 padding in the async cb.

ec095263a9 net: remove noblock parameter from recvmsg() entities
The internal recvmsg() functions have two parameters 'flags' and 'noblock'
that were merged inside skb_recv_datagram(). As a follow up patch to commit
f4b41f062c ("net: remove noblock parameter from skb_recv_datagram()")
this patch removes the separate 'noblock' parameter for recvmsg().

Analogue to the referenced patch for skb_recv_datagram() the 'flags' and
'noblock' parameters are unnecessarily split up with e.g.

err = sk->sk_prot->recvmsg(sk, msg, size, flags & MSG_DONTWAIT,
                           flags & ~MSG_DONTWAIT, &addr_len);

or in

err = INDIRECT_CALL_2(sk->sk_prot->recvmsg, tcp_recvmsg, udp_recvmsg,
                      sk, msg, size, flags & MSG_DONTWAIT,
                      flags & ~MSG_DONTWAIT, &addr_len);

instead of simply using only flags all the time and check for MSG_DONTWAIT
where needed (to preserve for the formerly separated no(n)block condition).

80ecb114f2 Merge branch 'net-dsa-mt7530-updates-for-phylink-changes'
Russell King says:

====================
net: dsa: mt7530: updates for phylink changes

This revised series is a partial conversion of the mt7530 DSA driver to
the modern phylink infrastructure. This driver has some exceptional
cases which prevent - at the moment - its full conversion (particularly
with the Autoneg bit) to using phylink_generic_validate().

Patch 1 fixes the incorrect test highlighted in the first RFC series.

Patch 2 fixes the incorrect assumption that RGMII is unable to support
1000BASE-X.

Patch 3 populates the supported_interfaces for each port

Patch 4 removes the interface checks that become unnecessary as a result
of patch 3.

Patch 5 removes use of phylink_helper_basex_speed() which is no longer
required by phylink.

Patch 6 becomes possible after patch 5, only indicating the ethtool
modes that can be supported with a particular interface mode - this
involves removing some modes and adding others as per phylink
documentation.

Patch 7 switches the driver to use phylink_get_linkmodes(), which moves
the driver as close as we can to phylink_generic_validate() due to the
Autoneg bit issue mentioned above.

Patch 8 converts the driver to the phylink pcs support, removing a bunch
of driver private indirected methods. We include TRGMII as a PCS even
though strictly TRGMII does not have a PCS. This is convenient to allow
the change in patch 9 to be made.

Patch 9 moves the special autoneg handling to the PCS validate method,
which means we can convert the MAC side to the generic validator.

Patch 10 marks the driver as non-legacy.

The series was posted on 23 February, and a ping sent on 3 March, but
no feedback has been received. The previous posting also received no
feedback on the actual patches either.

v2:
- fix build issue in patch 5
- add Marek's tested-by

which are supported is a property of the PHY.

Therefore, it makes no sense to exclude this from the linkmodes when

e65693b017 net: bridge: add support for host l2 mdb entries
This patch expands on the earlier work on layer-2 mdb entries by adding
support for host entries.  Due to the fact that host joined entries do
not have any flag field, we infer the permanent flag when reporting the
entries to userspace, which otherwise would be listed as 'temp'.

Before patch:

    ~# bridge mdb add dev br0 port br0 grp 01:00:00:c0:ff:ee permanent
    Error: bridge: Flags are not allowed for host groups.
    ~# bridge mdb add dev br0 port br0 grp 01:00:00:c0:ff:ee
    Error: bridge: Only permanent L2 entries allowed.

After patch:

    ~# bridge mdb add dev br0 port br0 grp 01:00:00:c0:ff:ee permanent
    ~# bridge mdb show
    dev br0 port br0 grp 01:00:00:c0:ff:ee permanent vid 1

c3976a3f84 net: bridge: offload BR_HAIRPIN_MODE, BR_ISOLATED, BR_MULTICAST_TO_UNICAST
Add BR_HAIRPIN_MODE, BR_ISOLATED and BR_MULTICAST_TO_UNICAST port flags to
BR_PORT_FLAGS_HW_OFFLOAD so that switchdev drivers which have an offloaded
data plane have a chance to reject these bridge port flags if they don't
support them yet.

It makes the code path go through the
SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS driver handlers, which return
-EINVAL for everything they don't recognize.

For drivers that don't catch SWITCHDEV_ATTR_ID_PORT_PRE_BRIDGE_FLAGS at
all, switchdev will return -EOPNOTSUPP for those which is then ignored, but
those are in the minority.

====================
net: lan966x: Add support for FDMA

Currently when injecting or extracting a frame from CPU, the frame
is given to the HW each word at a time. There is another way to
inject/extract frames from CPU using FDMA(Frame Direct Memory Access).
In this way the entire frame is given to the HW. This improves both
RX and TX bitrate.

c834963932 net: lan966x: Add FDMA functionality
Ethernet frames can be extracted or injected to or from the device's
DDR memory. There is one channel for injection and one channel for
extraction. Each of these channels contain a linked list of DCBs which
contains DB. The DCB contains only 1 DB for both the injection and
extraction. Each DB contains a frame. Every time when a frame is received
or transmitted an interrupt is generated.

It is not possible to use both the FDMA and the manual
injection/extraction of the frames. Therefore the FDMA has priority over
the manual because of better performance values.

Mellanox shared branch that includes:

 * Removal of FPGA TLS code https://lore.kernel.org/all/cover.1649073691.git.leonro@nvidia.com

  Mellanox INNOVA TLS cards are EOL in May, 2018 [1]. As such, the code
  is unmaintained, untested and not in-use by any upstream/distro oriented
  customers. In order to reduce code complexity, drop the kernel code,
  clean build config options and delete useless kTLS vs. TLS separation.

  [1] https://network.nvidia.com/related-docs/eol/LCR-000286.pdf

 * Removal of FPGA IPsec code https://lore.kernel.org/all/cover.1649232994.git.leonro@nvidia.com

  Together with FPGA TLS, the IPsec went to EOL state in the November of
  2019 [1]. Exactly like FPGA TLS, no active customers exist for this
  upstream code and all the complexity around that area can be deleted.
