If there's no traffic on a channel, its ARFS expiry work will never get
scheduled by efx_poll() as that isn't being run.
So make efx_filter_rfs_expire() reschedule itself to run after 30 seconds.

In high connection count usage, the NIC's filter table may be filled with
sufficiently many ARFS filters that further insertions fail. As this
does not represent a correctness issue, do not log the resulting MCDI
errors. Add a debug-level message under the (by default disabled)
rx_status category instead; and take the opportunity to do a little extra
expiry work.
Since there are now multiple workitems able to call __efx_filter_rfs_expire
on a given channel, it is possible for them to race and thus pass quotas
which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop
all the way around the table with quota left over.

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.
v2:
- No change.

This reverts commit 68b9c5066e39af41d3448abfc887c77ce22dd64d.
Ugh, I really dropped the ball on this one :\. So as it turns out RMI4
works perfectly fine on the X1 Extreme Gen 2 except for one thing I
didn't notice because I usually use the trackpoint: clicking with the
touchpad. Somehow this is broken, in fact we don't even seem to indicate
BTN_LEFT as a valid event type for the RMI4 touchpad. And, I don't even
see any RMI4 events coming from the touchpad when I press down on it.
This only seems to work for PS/2 mode.
Since that means we have a regression, and PS/2 mode seems to work fine
for the time being - revert this for now. We'll have to do a more
thorough investigation on this.

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

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.
This allows us to remove the call to
ice_vsi_manage_vlan_stripping() in ice_vc_process_vlan_msg().
