Some IDT switches incorrectly flag an ACS Source Validation error on
completions for config read requests even though PCIe r4.0, sec 6.12.1.1,
says that completions are never affected by ACS Source Validation.  Here's
the text of IDT 89H32H8G3-YC, erratum #36:

  Item #36 - Downstream port applies ACS Source Validation to Completions
  Section 6.12.1.1 of the PCI Express Base Specification 3.1 states that
  completions are never affected by ACS Source Validation.  However,
  completions received by a downstream port of the PCIe switch from a
  device that has not yet captured a PCIe bus number are incorrectly
  dropped by ACS Source Validation by the switch downstream port.

  Workaround: Issue a CfgWr1 to the downstream device before issuing the
  first CfgRd1 to the device.  This allows the downstream device to capture
  its bus number; ACS Source Validation no longer stops completions from
  being forwarded by the downstream port.  It has been observed that
  Microsoft Windows implements this workaround already; however, some
  versions of Linux and other operating systems may not.

When doing the first config read to probe for a device, if the device is
behind an IDT switch with this erratum:

  1. Disable ACS Source Validation if enabled
  2. Wait for device to become ready to accept config accesses (by using
     the Config Request Retry Status mechanism)
  3. Do a config write to the endpoint
  4. Enable ACS Source Validation (if it was enabled to begin with)

The workaround suggested by IDT is basically only step 3, but we don't know
when the device is ready to accept config requests.  That means we need to
do config reads until we receive a non-Config Request Retry Status, which
means we need to disable ACS SV temporarily.

Switchdev notifications for addition of SWITCHDEV_OBJ_ID_PORT_VLAN are
distributed not only on clean addition, but also when flags on an
existing VLAN are changed. mlxsw_sp_bridge_port_vlan_add() calls
mlxsw_sp_port_vlan_get() to get at the port_vlan in question, which
implicitly references the object. This then leads to discrepancies in
reference counting when the VLAN is removed. spectrum.c warns about the
problem when the module is removed:

stmmac reception handler calls stmmac_rx_vlan() to strip the vlan before
calling napi_gro_receive().

The function assumes VLAN tagged frames are always tagged with
802.1Q protocol, and assigns ETH_P_8021Q to the skb by hard-coding
the parameter on call to __vlan_hwaccel_put_tag() .

This causes packets not to be passed to the VLAN slave if it was created
with 802.1AD protocol
(ip link add link eth0 eth0.100 type vlan proto 802.1ad id 100).

This fix passes the protocol from the VLAN header into
__vlan_hwaccel_put_tag() instead of using the hard-coded value of
ETH_P_8021Q.

NETIF_F_HW_VLAN_STAG_RX check was added and the strip action is now
dependent on the correct combination of features and the detected vlan tag.

NETIF_F_HW_VLAN_STAG_RX feature was added to be in line with the driver
actual abilities.

Current code follows the framework that has been in the transports
from the beginning where initial link-side controller connect occurs
as part of "creating the controller". Thus that first connect fully
talks to the controller and obtains values that can then be used in
for blk-mq setup, etc. It also means that everything about the
controller is fully know before the "create controller" call returns.

This has several weaknesses:
- The initial create_ctrl call made by the cli will block for a long
  time as wire transactions are performed synchronously. This delay
  becomes longer if errors occur or connectivity is lost and retries
  need to be performed.
- Code wise, it means there is a separate connect path for initial
  controller connect vs the (same) steps used in the reconnect path.
- And as there's separate paths, it means there's separate error
  handling and retry logic. It also plays havoc with the NEW state
  (should transition out of it after successful initial connect) vs
  the RESETTING and CONNECTING (reconnect) states that want to be
  transitioned to on error.
- As there's separate paths, to recover from errors and disruptions,
  it requires separate recovery/retry paths as well and can severely
  convolute the controller state.

This patch reworks the fc transport to use the same connect paths
for the initial connection as it uses for reconnect. This makes a
single path for error recovery and handling.

This patch:
- Removes the driving of the initial connect and replaces it with
  a state transition to CONNECTING and initiating the reconnect
  thread. A dummy state transition of RESETTING had to be traversed
  as a direct transtion of NEW->CONNECTING is not allowed. Given
  that the controller is "new", the RESETTING transition is a simple
  no-op. Once in the reconnecting thread, the normal behaviors of
  ctrl_loss_tmo (max_retries * connect_delay) and dev_loss_tmo will
  apply before the controller is torn down.
- Only if the state transitions couldn't be traversed and the
  reconnect thread not scheduled, will the controller be torn down
  while in create_ctrl.
- The prior code used the controller state of NEW to indicate
  whether request queues had been initialized or not. For the admin
  queue, the request queue is always created, so there's no need to
  check a state. For IO queues, change to tracking whether a successful
  io request queue create has occurred (e.g. 1st successful connect).
- The initial controller id is initialized to the dynamic controller
  id used in the initial connect message. It will be overwritten by
  the real controller id once the controller is connected on the wire.

So, unfortunately I recently made the discovery that in the upstream
kernel, the only reason that amdgpu is not currently suffering from
issues with runtime PM putting the GPU into suspend while it's driving
displays is due to the fact that on most prime systems, we have sound
devices associated with the GPU that hold their own runtime PM ref for
the GPU.

What this means however, is that in the event that there isn't any kind
of sound device active (which can easily be reproduced by building a
kernel with sound drivers disabled), the GPU will fall asleep even when
there's displays active. This appears to be in part due to the fact that
amdgpu has not actually ever relied on it's rpm_idle() function to be
the only thing keeping it running, and normally grabs it's own power
references whenever there are displays active (as can be seen with the
original pre-DC codepath in amdgpu_display_crtc_set_config() in
amdgpu_display.c). This means it's very likely that this bug was
introduced during the switch over the DC.

So to fix this, we start grabbing runtime PM references every time we
enable a previously disabled CRTC in atomic_commit_tail(). This appears
to be the correct solution, as it matches up with what i915 does in
i915/intel_runtime_pm.c.

The one sideaffect of this is that we ignore the variable that the
pre-DC code used to use for tracking when it needed runtime PM refs,
adev->have_disp_power_ref. This is mainly because there's no way for a
driver to tell whether or not all of it's CRTCs are enabled or disabled
when we've begun committing an atomic state, as there may be CRTC
commits happening in parallel that aren't contained within the atomic
state being committed. So, it's safer to just get/put a reference for
each CRTC being enabled or disabled in the new atomic state.
