The old rfs_filters_added method for determining the quota could potentially
 allow the NIC to become filled with old filters, which never get tested for
 expiry.  Instead, explicitly make expiry check work depend on the number of
 filters installed, and don't count checking slots without filters in as
 doing work.  This guarantees that each filter will be checked for expiry at
 least once every thirty seconds (assuming the channel to which it belongs is
 NAPI polling actively) regardless of fill level.

Jeff Kirsher says:

====================
This series contains updates to the ice driver only.

Bruce updates the driver to store the number of functions the device has
so that it won't have to compute it when setting safe mode capabilities.
Adds a check to adjust the reporting of capabilities for devices with
more than 4 ports, which differ for devices with less than 4 ports.

Brett adds a helper function to determine if the VF is allowed to do
VLAN operations based on the host's VF configuration.  Also adds a new
function that initializes VLAN stripping (enabled/disabled) for the VF
based on the device supported capabilities.  Adds a check if the vector
index is valid with the respect to the number of transmit and receive
queues configured when we set coalesce settings for DCB.  Adds a check
if the promisc_mask contains ICE_PROMISC_VLAN_RX or ICE_PROMISC_VLAN_TX
so that VLAN 0 promiscuous rules to be removed.  Add a helper macro for
a commonly used de-reference of a pointer to &pf->dev->pdev.

Jesse fixes an issue where if an invalid virtchnl request from the VF,
the driver would return uninitialized data to the VF from the PF stack,
so ensure the stack variable is initialized earlier.  Add helpers to the
virtchnl interface make the reporting of strings consistent and help
reduce stack space.  Implements VF statistics gathering via the kernel
ndo_get_vf_stats().

Akeem ensures we disable the state flag for each VF when its resources
are returned to the device.

Tony does additional cleanup in the driver to ensure the when we
allocate and free memory within the same function, we should not be
using devm_* variants; use regular alloc and free functions.

Henry implements code to query and set the number of channels on the
primary VSI for a PF via ethtool.

Jake cleans up needless NULL checks in ice_sched_cleanup_all().

Kevin updates the firmware API version to align with current NVM images.

v2: Added "Fixes:" tag to patch 5 commit description and added the use
    of netif_is_rxfh_configured() in patch 13 to see if RSS has been
    configured by the user, if so do not overwrite that configuration.

The FW_ETH_TX_EO_WR used for sending UDP Segmentation Offload (USO)
requests expects the headers to be part of the descriptor and the
payload to be part of the SGL containing the DMA mapped addresses.
Hence, the DMA address in the first entry of the SGL can start after
the packet headers. Currently, unmap_sgl() tries to unmap from this
wrong offset, instead of the originally mapped DMA address.

So, use existing unmap_skb() instead, which takes originally saved DMA
addresses as input. Update all necessary Tx paths to save the original
DMA addresses, so that unmap_skb() can unmap them properly.

mailbox communication to clear its resources as well fails - since we
already indicate that PF is in disable state, with all VFs not active. In
addition, we don't need to notify VF that PF is intending to reset it, if

Currently when adding/deleting vlans in ice_vc_process_vlan_msg()
we are calling ice_vsi_manage_vlan_stripping() to enable/disable
when adding and deleting a VLAN respectively. This is wrong
because adding/deleting VLANs has nothing to do with configuring
VLAN stripping. VLAN stripping is configured through the
following VIRTCHNL operations:
	VIRTCHNL_OP_ENABLE_VLAN_STRIPPING
	VIRTCHNL_OP_DISABLE_VLAN_STRIPPING

Unfortunately we can't just remove this because then stripping
will never be configured on VF initialization. Fix this by
adding a new function that initializes (disables/enables) VLAN
stripping for the VF based on the device supported capabilities.

be able to deliver decapsulated packets that are destined to local

to maintain compatibility I created another routing helper function which
is called seg6_lookup_any_nexthop(). This function is able to take into
account both packets that have to be processed locally and the ones that
are destined to be forwarded directly to another machine. Hence,
seg6_lookup_any_nexthop() is used in DT6 rather than seg6_lookup_nexthop()

It is observed that TIPC service binding order will not be kept in the
publication event report to user if the service is subscribed after the
bindings.

For example, services are bound by application in the following order:

Server: bound port A to {18888,66,66} scope 2
Server: bound port A to {18888,33,33} scope 2

Now, if a client subscribes to the service range (e.g. {18888, 0-100}),
it will get the 'TIPC_PUBLISHED' events in that binding order only when
the subscription is started before the bindings.
Otherwise, if started after the bindings, the events will arrive in the
opposite order:

Client: received event for published {18888,33,33}
Client: received event for published {18888,66,66}

For the latter case, it is clear that the bindings have existed in the
name table already, so when reported, the events' order will follow the
order of the rbtree binding nodes (- a node with lesser 'lower'/'upper'
range value will be first).

This is correct as we provide the tracking on a specific service status
(available or not), not the relationship between multiple services.
However, some users expect to see the same order of arriving events
irrespective of when the subscription is issued. This turns out to be
easy to fix. We now add functionality to ensure that publication events
always are issued in the same temporal order as the corresponding
bindings were performed.

v2: replace the unnecessary macro - 'publication_after()' with inline
function.
v3: reuse 'time_after32()' instead of reinventing the same exact code.

Pull power management regression fix from Rafael Wysocki:
 "Fix problems with switching cpufreq drivers on some x86 systems with
  ACPI (and with changing the operation modes of the intel_pstate driver
  on those systems) introduced by recent changes related to the
  management of frequency limits in cpufreq"

* tag 'pm-5.4-final' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM: QoS: Invalidate frequency QoS requests after removal

Pull drm fixes from Dave Airlie:
 "Two sets of fixes in here, one for amdgpu, and one for i915.

  The amdgpu ones are pretty small, i915's CI system seems to have a few
  problems in the last week or so, there is one major regression fix for
  fb_mmap, but there are a bunch of other issues fixed in there as well,
  oops, screen flashes and rcu related.

  amdgpu:
   - Remove experimental flag for navi14
   - Fix confusing power message failures on older VI parts
   - Hang fix for gfxoff when using the read register interface
   - Two stability regression fixes for Raven

  i915:
   - Fix kernel oops on dumb_create ioctl on no crtc situation
   - Fix bad ugly colored flash on VLV/CHV related to gamma LUT update
   - Fix unity of the frequencies reported on PMU
   - Fix kernel oops on set_page_dirty using better locks around it
   - Protect the request pointer with RCU to prevent it being freed
     while we might need still
   - Make pool objects read-only
   - Restore physical addresses for fb_map to avoid corrupted page
     table"
