===============

The multiport eswitch feature allows to forward traffic from a
representor net device to the uplink port of an associated eswitch's
uplink port.

This feature requires creating a LAG object. Since LAG can be created
only once for a function, the feature is mutual exclusive with either
bonding or multipath.

Multipath eswitch mode is entered automatically these conditions are
met:
1. No other LAG related mode is active.
2. A rule that explicitly forwards to an uplink port is inserted.

The implementation maintains a reference count on such rules. When the
reference count reaches zero, the LAG is released and other modes may be
used.

When an explicit rule that explicitly forwards to an uplink port is
inserted while another LAG mode is active, that rule will not be
offloaded by the hardware since the hardware cannot guarantee that the
rule will actually be forwarded to that port.

Example rules that forwards to an uplink port is:

$ tc filter add dev rep0 root flower action mirred egress \
  redirect dev uplinkrep0

$ tc filter add dev rep0 root flower action mirred egress \
  redirect dev uplinkrep1

This feature is supported only if LAG_RESOURCE_ALLOCATION firmware
configuration parameter is set to true.

The series consists of three patches:
1. Lag state machine refactor
   This patch does not add new functionality but rather changes the way
   the state of the LAG is maintained.
2. Small fix to remove unused argument.

net/mlx5: Support multiport eswitch mode

Multiport eswitch mode is a LAG mode that allows to add rules that
forward traffic to a specific physical port without being affected by LAG
affinity configuration.

This mode of operation is mutual exclusive with the other LAG modes used
by multipath and bonding.

To make the transition between the modes, we maintain a counter on the
number of rules specifying one of the uplink representors as the target
of mirred egress redirect action.

An example of such rule would be:

$ tc filter add dev enp8s0f0_0 prot all root flower dst_mac \
  00:11:22:33:44:55 action mirred egress redirect dev enp8s0f0

If the reference count just grows to one and LAG is not in use, we
create the LAG in multiport eswitch mode. Other mode changes are not
allowed while in this mode. When the reference count reaches zero, we
destroy the LAG and let other modes be used if needed.

logic also changed such that if forwarding to some uplink destination
cannot be guaranteed, we fail the operation so the rule will eventually
be in software and not in hardware.

net/mlx5e: Wrap mlx5e_trap_napi_poll into rcu_read_lock

The body of mlx5e_napi_poll is wrapped into rcu_read_lock to be able to
read the XDP program pointer using rcu_dereference. However, the trap RQ
NAPI doesn't use rcu_read_lock, because the trap RQ works only in the
non-linear mode, and mlx5e_skb_from_cqe_nonlinear, until recently,
didn't support XDP and didn't call rcu_dereference.

Starting from the cited commit, mlx5e_skb_from_cqe_nonlinear supports
XDP and calls rcu_dereference, but mlx5e_trap_napi_poll doesn't wrap it
into rcu_read_lock. It leads to RCU-lockdep warnings like this:

    WARNING: suspicious RCU usage

This commit fixes the issue by adding an rcu_read_lock to
mlx5e_trap_napi_poll, similarly to mlx5e_napi_poll.

net/mlx5: DR, Ignore modify TTL on RX if device doesn't support it

When modifying TTL, packet's csum has to be recalculated.
Due to HW issue in ConnectX-5, csum recalculation for modify
TTL on RX is supported through a work-around that is specifically
enabled by configuration.
If the work-around isn't enabled, rather than adding an unsupported
action the modify TTL action on RX should be ignored.
Ignoring modify TTL action might result in zero actions, so in such
cases we will not convert the match STE to modify STE, as it is done
by FW in DMFS.

on RX and TX instead of only on RX.

    * create and destroy: namespaces initialization and cleanup.

There are sleep in atomic context bugs when the request to secure
element of st-nci is timeout. The root cause is that nci_skb_alloc
with GFP_KERNEL parameter is called in st_nci_se_wt_timeout which is
a timer handler. The call paths that could trigger bugs are shown below:

    (interrupt context 1)
st_nci_se_wt_timeout
  nci_hci_send_event
    nci_hci_send_data
      nci_skb_alloc(..., GFP_KERNEL) //may sleep

    nci_hci_send_data
      nci_send_data
        nci_queue_tx_data_frags
          nci_skb_alloc(..., GFP_KERNEL) //may sleep

This patch changes allocation mode of nci_skb_alloc from GFP_KERNEL to
GFP_ATOMIC in order to prevent atomic context sleeping. The GFP_ATOMIC
flag makes memory allocation operation could be used in atomic context.

QL_RESET_START (i.e. 3) is set.

In fact, it checks if bit 7 (4 | 3 = 7) is set, that is to say
QL_ADAPTER_UP.

rq->rx_ring[ring_idx].base is accessed, but this variable is NULL, causing
a NULL pointer dereference.

To fix this possible bug, an if statement is added to check whether

The case 1. is fixed by checking if the port has already the same
address while case 2. is fixed by checking if the address is used by any
other port.

Marc Kleine-Budde says:

====================
pull-request: can-next 2022-05-16

the first 2 patches are by me and target the CAN raw protocol. The 1st
removes an unneeded assignment, the other one adds support for
SO_TXTIME/SCM_TXTIME.

Oliver Hartkopp contributes 2 patches for the ISOTP protocol. The 1st
adds support for transmission without flow control, the other let's
bind() return an error on incorrect CAN ID formatting.

Geert Uytterhoeven contributes a patch to clean up ctucanfd's Kconfig
file.

Vincent Mailhol's patch for the slcan driver uses the proper function
to check for invalid CAN frames in the xmit callback.

The next patch is by Geert Uytterhoeven and makes the interrupt-names
of the renesas,rcar-canfd dt bindings mandatory.

A patch by my update the ctucanfd dt bindings to include the common
CAN controller bindings.

The last patch is by Akira Yokosawa and fixes a breakage the
ctucanfd's documentation.
