Add support for a new AF_XDP feature that has already been introduced in
upstreamed Intel NIC drivers. If a user space application signals that
it might sleep using the new bind flag XDP_USE_NEED_WAKEUP, the driver
will then set this flag if it has no more buffers on the NIC Rx ring and
yield to the application. For Tx, it will set the flag if it has no
outstanding Tx completion interrupts and return to the application.

Currently when the PF reduces its number of channels via ethtool and
then VFs are created there may be stale data for some of the Rx queues

previously used by the PF. Specifically, the QRXFLXP_CNTXT register

Update the PF VFs MDD event message to rate limit once per second and
report the total number Rx|Tx event count. Add support to print pending
MDD events that occur during the rate limit. The use of net_ratelimit did
not allow for per VF Rx|Tx granularity.

Additional PF MDD log messages are guarded by netif_msg_[rx|tx]_err().

Since VF RX MDD events disable the queue, add ethtool private flag
mdd-auto-reset-vf to configure VF reset to re-enable the queue.

Disable anti-spoof detection interrupt to prevent spurious events
during a function reset.

To avoid race condition do not make PF MDD register reads conditional
on global MDD result.

c54d209c78 ice: Wait for VF to be reset/ready before configuration
The configuration/command below is failing when the VF in the xml
file is already bound to the host iavf driver.

pci_0000_af_0_0.xml:

<interface type='hostdev' managed='yes'>
<source>
<address type='pci' domain='0x0000' bus='0xaf' slot='0x0' function='0x0'/>
</source>
<mac address='00🇩🇪ad:00:11:01'/>
</interface>

error: Failed to attach device from pci_0000_af_0_0.xml
error: Cannot set interface MAC/vlanid to 00🇩🇪ad:00:11:01/0 for
	ifname ens1f1 vf 0: Device or resource busy

This is failing because the VF has not been completely removed/reset
after being unbound (via the virsh command above) from the host iavf
driver and ice_set_vf_mac() checks if the VF is disabled before waiting
for the reset to finish.

Fix this by waiting for the VF remove/reset process to happen before
checking if the VF is disabled. Also, since many functions for VF
administration on the PF were more or less calling the same 3 functions
(ice_wait_on_vf_reset(), ice_is_vf_disabled(), and ice_check_vf_init())
move these into the helper function ice_check_vf_ready_for_cfg(). Then
call this function in any flow that attempts to configure/query a VF
from the PF.

Lastly, increase the maximum wait time in ice_wait_on_vf_reset() to
800ms, and modify/add the #define(s) that determine the wait time.
This was done for robustness because in rare/stress cases VF removal can
take a max of ~800ms and previously the wait was a max of ~300ms.

4e83fc934e ice: replace "fallthrough" comments with fallthrough reserved word
"fallthrough" comments are used in switch case statements to explicitly
indicate the code is intended to fall through to the following statement.
Different variants of "fallthough" are acceptable, e.g. "fall through",
"fallthrough", "Fall-through".  The GCC compiler has an optional warning
(-Wimplicit-fallthrough[=n]) to warn when such a comment is not present;
the default version of which is enabled when compiling the Linux kernel.

There have been recent discussions in kernel mailing lists regarding
replacing non-standardized "fallthrough" comments with the pseudo-reserved
word 'fallthrough' which will be defined as __attribute__ ((fallthrough))
for versions of gcc that support it (i.e. gcc 7 and newer) or as a nop
for versions that do not.  Replace "fallthrough" comments with fallthrough
reserved word.

24e2e2a0b8 ice: Fix virtchnl_queue_select bitmap validation
Currently in ice_vc_ena_qs_msg() we are incorrectly validating the
virtchnl queue select bitmaps. The virtchnl_queue_select rx_queues and
tx_queue bitmap is being compared against ICE_MAX_BASE_QS_PER_VF, but
the problem is that these bitmaps can have a value greater than
ICE_MAX_BASE_QS_PER_VF. Fix this by comparing the bitmaps against
BIT(ICE_MAX_BASE_QS_PER_VF).

Also, add the function ice_vc_validate_vqs_bitmaps() that checks to see
if both virtchnl_queue_select bitmaps are empty along with checking that
the bitmaps only have valid bits set. This function can then be used in
both the queue enable and disable flows.

Arkady Gilinksky's patch on the intel-wired-lan mailing list

e1fe692680 ice: Fix and refactor Rx queue disable for VFs
Currently when a VF driver sends the PF a request to disable Rx queues
we will disable them one at a time, even if the VF driver sent us a
batch of queues to disable. This is causing issues where the Rx queue
disable times out with LFC enabled. This can be improved by detecting
when the VF is trying to disable all of its queues.

Also remove the variable num_qs_ena from the ice_vf structure as it was
only used to see if there were no Rx and no Tx queues active. Instead
add a function that checks if both the vf->rxq_ena and vf->txq_ena
bitmaps are empty.

2309ae385a ice: Handle LAN overflow event for VF queues
Currently we are not handling LAN overflow events. There can be cases
where LAN overflow events occur on VF queues, especially with Link Flow
Control (LFC) enabled on the controlling PF. In order to recover from
the LAN overflow event caused by a VF we need to determine if the queue
belongs to a VF and reset that VF accordingly.

The struct ice_aqc_event_lan_overflow returns a copy of the GLDCB_RTCTQ
register, which tells us what the queue index is in the global/device
space. The global queue index needs to first be converted to a PF space
queue index and then it can be used to find if a VF owns it.

13a6233b03 ice: Add support to enable/disable all Rx queues before waiting
Currently when we enable/disable all Rx queues we do the following
sequence for each Rx queue and then move to the next queue.

1. Enable/Disable the Rx queue via register write.
2. Read the configuration register to determine if the Rx queue was
enabled/disabled successfully.

In some cases enabling/disabling queue 0 fails because of step 2 above.
Fix this by doing step 1 for all of the Rx queues and then step 2 for
all of the Rx queues.

Also, there are cases where we enable/disable a single queue (i.e.
SR-IOV and XDP) so add a new function that does step 1 and 2 above with
a read flush in between.

This change also required a single Rx queue to be enabled/disabled with
and without waiting for the change to propagate through hardware. Fix
this by adding a boolean wait flag to the necessary functions.

Also, add the keywords "one" and "all" to distinguish between
enabling/disabling a single Rx queue and all Rx queues respectively.

Currently the VF can see other's broadcast and multicast traffic because

present for load and reset.

2. Moved where we kill the old port VLAN filter in

us to save the old port VLAN configuration upon any failure case.

b093841f9a ice: Refactor port vlan configuration for the VF
Currently ice_vsi_manage_pvid() calls
ice_vsi_[set|kill]_pvid_fill_ctxt() when enabling/disabling a port VLAN
on a VSI respectively. These two functions have some duplication so just
move their unique pieces inline in ice_vsi_manage_pvid() and then the
duplicate code can be reused for both the enabling/disabling paths.

Before this patch the info.pvid field was not being written
correctly via ice_vsi_kill_pvid_fill_ctxt() so it was being hard coded
to 0 in ice_set_vf_port_vlan(). Fix this by setting the info.pvid field
to 0 before calling ice_vsi_update() in ice_vsi_manage_pvid().

We currently use vf->port_vlan_id to keep track of the port VLAN
ID and QoS, which is a bit misleading. Fix this by renaming it to
vf->port_vlan_info. Also change the name of the argument for
ice_vsi_manage_pvid() from vid to pvid_info.

In ice_vsi_manage_pvid() only save the fields that were modified
in the VSI properties structure on success instead of the entire thing.

Call cpu_latency_qos_add/update/remove_request() instead of
pm_qos_add/update/remove_request(), respectively, because the
latter are going to be dropped.

No intentional functional impact.

fbf1e1f698 ice: fix and consolidate logging of NVM/firmware version information
Logging the firmware/NVM information during driver load is redundant since
that information is also available via ethtool.  Move the functionality
found in ice_nvm_version_str() directly into ice_get_drvinfo() and remove
calling the former and logging that info during driver probe.  This also
gets rid of a bug in ice_nvm_version_str() where it returns a pointer to
a buffer which is free'ed when that function exits.

168983a8e1 ice: Don't allow same value for Rx tail to be written twice
Currently we compare the value we are about to write to the Rx tail
register with the previous value of next_to_use. The problem with this
is we only write tail on 8 descriptor boundaries, but next_to_use is
updated whenever we clean Rx descriptors. Fix this by comparing the
value we are about to write to tail with the previously written tail
value. This will prevent duplicate Rx tail bumps.

53977ee474 ice: Fix switch between FW and SW LLDP
When switching between FW and SW LLDP mode, the
number of configured TLV apps in the driver's
DCB configuration is getting out of synch with
what lldpad thinks is configured.  This is causing
a problem when shutting down lldpad.  The cleanup
is trying to delete TLV apps that are not defined
in the kernel.

Since the driver is keeping an accurate account
of the apps defined, use the drivers number of
apps to determine if there is an app to delete.
If the number of apps is <= 1, then do not
attempt to delete.

242b5e068b ice: Fix DCB rebuild after reset
The function ice_dcb_rebuild had some logic
flaws in it, and also didn't differentiate
between FW and SW modes needs.

For FW flow, the willing setting was being
forced to OFF and left that way.  Unwilling
in DCB FW mode is not a supported model.

Leave the config alone and use the return value
from the set command to determine if setting the
config was successful.

The SW DCB flow does not need to need to register
for MIB change events (as they are not used in
SW mode).

Use !is_sw_lldp checks to only perform FW specific
task while in FW mode.

Also adding a reapplication of the current DCB
config after a link event.  Some NVMs are not
maintaining their DCB configs across link events.
