It may need hold Global Config Lock a longer time when download DDP
package file, extend the timeout value to 5000ms to ensure that
download can be finished before other AQ command got time to run,
this will fix the issue below when probe the device, 5000ms is a test

[ Upstream commit f9f83202b7263ac371d616d6894a2c9ed79158ef ]
Currently in the ice driver, the check whether to
allow a LLDP packet to egress the interface from the
PF_VSI is being based on the SKB's priority field.
It checks to see if the packets priority is equal to
TC_PRIO_CONTROL. Injected LLDP packets do not always
meet this condition.
SCAPY defaults to a sk_buff->protocol value of ETH_P_ALL
(0x0003) and does not set the priority field. There will
be other injection methods (even ones used by end users)
that will not correctly configure the socket so that
SKB fields are correctly populated.
Then ethernet header has to have to correct value for
the protocol though.
Add a check to also allow packets whose ethhdr->h_proto
matches ETH_P_LLDP (0x88CC).

ice_add_to_vsi_fltr_list local copy of vsi filter list
is created. If any issues during creation of vsi filter
list occurs it up for the caller to free already

[ Upstream commit c0a3665f71a2f086800abea4d9d14d28269089d6 ]
This patch fixes the call trace caused by the kernel when the Rx/Tx
descriptor size change request is initiated via ethtool when DCB is
configured. ice_set_ringparam() should use vsi->num_txq instead of
vsi->alloc_txq as it represents the queues that are enabled in the
driver when DCB is enabled/disabled. Otherwise, queue index being
used can go out of range.
For example, when vsi->alloc_txq has 104 queues and with 3 TCS enabled
via DCB, each TC gets 34 queues, vsi->num_txq will be 102 and only 102
queues will be enabled.

If ice_init_interrupt_scheme fails, ice_probe will jump to clearing up
the interrupts. This can lead to some static analysis tools such as the
compiler sanitizers complaining about double free problems.
Since ice_init_interrupt_scheme already unrolls internally on failure,
there is no need to call ice_clear_interrupt_scheme when it fails. Add
a new unroll label and use that instead.

[ Upstream commit e25f9152bc07de534b2b590ce6c052ea25dd8900 ]

[ Upstream commit 1f9639d2fb9188a59acafae9dea626391c442a8d ]
It is wrong to set PF disable state flag for all VFs when freeing VF
resources - Instead, we should set VF disable state flag for each VF with
its resources being returned to the device. Right now, all VF opcodes,
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
it is already in disabled state.

Change the default number of descriptors to 2048.
The user can always change the value at runtime. Transmit descriptor
counts are not modified because they don't need to change due to the
speed of the interface, or for power managed CPUs, but the code is

Remove q_left_tx and q_left_rx from the PF struct as these can be
obtained by calling ice_get_avail_txq_count and ice_get_avail_rxq_count
respectively.
The function ice_determine_q_usage is only setting num_lan_tx and
num_lan_rx in the PF structure, and these are later assigned to
vsi->alloc_txq and vsi->alloc_rxq respectively. This is an unnecessary
indirection, so remove ice_determine_q_usage and just assign values

erroneous information, especially when queues have not been configured.
In addition, we can also make a call to get and report link status change
after when queue is enabled, at least to report netdev or PHY link status.

This is port of a fix from i40e commit 2ad1274fa35a ("i40e: don't
report link up for a VF who hasn't enabled queues")
Older VF drivers do not respond well to receiving a link
up notification before queues are enabled. This can cause their state
machine to think that it is safe to send traffic. This results in a Tx
hang on the VF.
Record whether the PF has actually enabled queues for the VF. When
reporting link status, always report link down if the queues aren't
enabled. In this way, the VF driver will never receive a link up
notification until after its queues are enabled.

When a PFR (or bigger reset) occurs, the device clears the VF_MBX_ARQLEN
register for all VFs. But if a VFR is triggered by a VF, the device does
NOT clear this register, and the VF driver will never see the reset.
When this happens, the VF driver will eventually timeout and attempt
recovery, and usually it will be successful. But this makes resets take
a long time and there are occasional failures.
We cannot just blithely clear this register on every reset; this has
been shown to cause synchronization problems when a PFR is triggered
with a large number of VFs.
Fix this by clearing VF_MBX_ARQLEN when the reset source is not PFR.
GlobR will trigger PFR, so this test catches that occurrence as well.

The driver has supported a transmit work limit
that was configurable from ethtool for a long time, but
there are no good use cases for having it be a variable
that can be changed at run time. In addition, this
variable was noted to be causing performance overhead
due to cache misses.
Just remove the variable and let the code use a constant
so that the functionality is maintained (a limit on the
number of transmits that will be cleaned in any one call
to the clean routines) without the cache miss.
Removes code, removes a variable, removes testing surface. Yay.

Currently when vsi->req_txqs or vsi->req_rxqs are set we don't
correctly set the number of vsi->num_q_vectors. Fix this by
setting the number of queue vectors based on the max
between the vsi->alloc_txqs and vsi->alloc_rxqs.

Currently if the VF adds a VLAN, VLAN pruning will be enabled for that VSI.
Also, when a VLAN gets deleted it will disable VLAN pruning even if other
VLAN(s) exists for the VF. Fix this by only disabling VLAN pruning on the
VF VSI when removing the last VF (i.e. vf->num_vlan == 0).

Remove code that enables DCB in initialization when SW LLDP is
activated. DCB flag is set or reset before in ice_init_pf_dcb
based on number of TCs. So there is not need to overwrite it.
Setting DCB without checking number of TCs can cause communication
problems with other cards. Host card sends packet with VLAN priority
tag, but client card doesn't strip this tag and ping doesn't work.

There is currently a check in get_ndo_stats that
returns before updating stats if the VSI is down
or there are no Tx or Rx queues. This causes the
netdev to report zero stats with the netdev is down.
Remove the check so that the behavior of reporting
stats is the same as it was in IXGBE.

The call to ice_dis_vsi_txq() acts as the notification to the firmware
that the VF is being reset. Because of this, we need to make this call
every time we reset, regardless of whatever else we do to stop the Tx
queues.
Without this change, VF resets would fail to complete on interfaces that
were up and running.

In the init path for DCB, the call to ice_init_dcb()
can return a non-zero value for either an actual
error, or due to the FW lldp engine being stopped.
We are currently treating all non-zero values only as
an indication that the FW LLDP engine is stopped.
Check for an actual error in the DCB init flow.

This patch limits the max TCs set by the driver to the value provided by
the firmware as per the capabilities of the device. Otherwise, hard coding
to 8 TC max would fail the device configurations with more than 4 ports.

Conventionally, if the #defines/other are not needed by other header
files being included, #includes are done first followed by #defines
and other stuff. Move the #defines before the #includes to follow this
convention.
