69129dc39f i40e: Modify Tx disable wait flow in case of DCB reconfiguration
When DCB TC configuration changes the firmware suspends the port's Tx.
Now, as DCB TCs may have changed the PF driver tries to reconfigure the
TC configuration of the VSIs it manages. As part of this process it disables
the VSI queues but the Tx queue disable will not complete as the port's
Tx has been suspended. So, waiting for Tx queues to go to disable state
in this flow may lead to detection of Tx queue disable timeout errors.

Hence, this patch adds a new PF state so that if a port's Tx is in
suspended state the Tx queue disable flow would just put the request for
the queue to be disabled and return without waiting for the queue to be
actually disabled.
Once the VSI(s) TC reconfiguration has been done and driver has called
firmware AQC "Resume PF Traffic" the driver checks the Tx queues requested
to be disabled are actually disabled before re-enabling them again.

23cd1f095a i40e: Update VEB's enabled_tc after reconfiguration
When the port TC configuration changes as a result of DCBx the driver
modifies the enabled TCs for the VEBs it manages. But, in the process
it did not update the enabled_tc value that it caches on a per VEB basis.

So, when the next reconfiguration event occurs where the number of TC
value is same as the value cached in enabled_tc for a given VEB; driver
does not modify it's TC configuration by calling appropriate AQ command
believing it is running with the same configuration as requested.
Now, as the VEB is not actually enabled for the TCs that are there any
TC configuration command for VSI attached to that VEB with TCs that are
not enabled for the VEB fails.

This patch fixes this issue.

e1c4751ee2 i40e: Check for LLDP AdminStatus before querying DCBX
This patch adds a check whether LLDP Agent's default AdminStatus is

the DCBX status to disabled as well; and would not query firmware for
any DCBX configuration data.

2fd75f31f6 i40e: Resume Port Tx after DCB event
When there are DCB configuration changes based on DCBX the firmware suspends
the port's Tx and generates an event to the PF. The PF is then responsible
to reconfigure the PF VSIs and switching topology as per the updated DCB
configuration and then resume the port's Tx by calling the "Resume Port Tx"
AQ command.

This patch adds this call to the flow that handles DCB re-configuration in
the PF.

c5c2f7c360 i40e: re-enable VFLR interrupt sooner
VF interrupt processing takes a looooong time, and it's possible that we
could lose a VFLR event if it happens while we're processing a VFLR on
another VF. This would leave the VF in a semi-permanent reset state,
which would not be cleared until yet another VF experiences a VFLR.

To correct this situation, we enable the VFLR interrupt cause before we
begin processing any pending resets. This means that any VFLR that
occurs during reset processing will generate another interrupt and this
routine will get called again.

This change may cause a spurious interrupt when multiple VFLRs occur
very close together in time. If this happens, then this routine will be
called again and it will detect no outstanding VFLR events and do
nothing. No harm, no foul.

215367171b i40e: don't do link_status or stats collection on every ARQ
The ARQ events cause a service_task execution, and we do a link_status
check and full stats gathering for each service_task.  However, when
there are a lot of ARQ events, such as when doing an NVM update, we end up
doing 10's if not 100's of these per second, thereby heavily abusing the
PCI bus and especially the Firmware.  This patch adds a check to keep the
service_task from running these periodic tasks more than once per second,
while still allowing quick action to service the events.

We shouldn't restart Admin queue subtask if PF reset fails since we do
not have the AQ setup at that point. This patch makes sure we disable AQ
clean subtask when PF reset fails.

This will resolve an occasional kernel panic when PF reset fails for
some reason.

30650cc552 i40e: quiet complaints when removing default MAC VLAN filter and make set_mac reversible
Older firmware has an incorrect MAC VLAN filter that needs to be replaced
at startup, and now newer firmware doesn't have this problem.  With this
change we no longer complain if the remove fails, and we only add the
new filter if the remove succeeded.

Setting a new LAA worked the first time, but didn't work well in successive
operations, including returning to the HW default address.  This simplifies
the code that was trying to be too smart.

Lastly, this pulls the hardware default mac address out into separate
handling code and keeps the broadcast filtering from getting munged.

f905dd62be i40e/i40evf: add max buf len to aq debug print helper
There is at least one case in the Firmware API where the response to a
command changes the buffer size field in the AQ descriptor to a larger
number than what the request's buffer size started as.  This is in addition
to setting an error flag and is in order to tell the requester how much
larger a buffer is required for the answer.  We need to be sure not to
use that number when dumping the contents of the data buffer because it
can send us into the weeds and generate an invalid pointer exception.

This patch adds a max buffer size parameter to the print helper to be
sure the code knows when to stop.

1e1be8f622 i40e: ATR policy change to flush the table to clean stale ATR rules
Instead of disabling ATR when we get a programming error, we now
will wait it out to see if some room gets created by ATR rule deletion.
If we still have too many errors and ATR filter count did not change
much, its time to flush and replay. We no more auto-disable ATR when
we have errors in programming.
The disabling of ATR when we get programming error was buggy and
was still adding new rules and causing continuous errors. With this
policy change we flush instead when we see too many errors.
ATR is still disabled if we add a SB rule for TCP/IPv4 flow type,
more logic is added to re-enable it once all SB TCP/IPv4 rules are gone.

3d34dd03d5 i40e: Fix TSO and hw checksums for non-accelerated vlan packets.
This device claims TSO and checksum support for vlans.  It also
allows a user to control vlan acceleration offloading.  As such,
it is possible to turn off vlan acceleration and configure a vlan
which will continue to support TSO and hw checksums.

In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO and checksum information.
This results in corrupted frames sent on the wire.

This patch extract the protocol value correctly and corrects TSO
and checksums for non-accelerated traffic.

Fix this by using vlan_get_protocol() helper.

fix to be able to send messages to all VFS which earlier was not

are up but also to VFS that are not up.  AQ complains about this and
sends us an error in ARQ called LAN overflow event for a queue. We
check if the queue belongs to a VF and if it does we try to send a
vc_notify_vf_reset message to that VF. Well if the VF is not up/enabled
we will be entering this function with a non-active VF id. In this
function we were assuming VF struct is populated but it won't be if
the VF is not active.

89cb86c3b2 i40e: remove support for vf unicast promiscuous mode
Remove the ability of a VF to set unicast promiscuous mode.
Considered to be a security risk to allow VFs to receive traffic
intended for other VFs so don't allow it, simply ignore the flag.

Also fix it to send the correct seid to aq for multicast promiscuous set.

the code was checking TCP on inner protocol, as that code

cd552cb49e i40e/i40evf: Add nvmupdate support
This implements a state machine intended to support the userland tool for
updating the device eeprom. The state machine implements one-shot reads,
writes, multi-step write sessions, and checksum requests. If we're in the middle
of a multi-step write session, no one should fire off other writes, however, one
shot reads are valid. The userland tool is expected to keep track of its session
status, arrange the placement and ordering of the writes, and deal with the
checksum requirement.

This patch also adds nvmupdate support to ethtool callbacks.
The get_eeprom() and set_eeprom() services in ethtool are used here to
facilitate the userland NVMUpdate tool.  The 'magic' value in the get and
set commands is used to pass additional control information for managing
the read and write steps.

The read operation works both as normally expected in the standard ethtool
method, as well as with the extra NVM controls.  The write operation
works only for the expanded NVM functions - the normal ethtool method is
not allowed because of the NVM semaphore management needed for multipart
writes, as well as the checksum requirement.

If the adapter has a valid per-port mac address then that
would be used for this purpose and is expected to be unique
on a per-port basis.

The information can be viewed by reading the phys_port_id
attribute in sysfs for each netdev or via IF netlink
interface.

49d7d93331 i40e/i40evf: Do not free the dummy packet buffer synchronously
The HW still needs to consume it and freeing it in the function
that created it would mean we will be racing with the HW. The
i40e_clean_tx_ring() routine will free up the buffer attached once
the HW has consumed it.  The clean_fdir_tx_irq function had to be fixed
to handle the freeing correctly.

Cases where we program more than one filter per flow (Ipv4), the
code had to be changed to allocate dummy buffer multiple times
since it will be freed by the clean routine.  This also fixes an issue
where the filter program routine was not checking if there were
descriptors available for programming a filter.

129573883c i40e: Fix the FD sideband logic to detect a FD table full condition
Hardware does not have a way of telling a PF how much of the global
shared FD table space is still available or is consumed.
Previously, every PF but PF0 would think there was still space available
when there wasn't. The PFs would continue to try to add filters and fail.
With this new logic if a filter programming error is detected we just
check if we are close to the guaranteed space full and that can be used
as a hint to say, there might not be space and we should turn off the
features. This way we can turn off the feature in SW for all PFs in
time.

fbd5e2df9f i40e: only create PTP device node once
Currently every time we run through the i40e_ptp_init routine, we create
a new device node. This function is called by i40e_reset_and_rebuild
which is used to handle reset of the device. Even though the 1588
registers only get cleared on a GLOBAL reset, this function is still
called to handle a CORE reset.

This causes a leak of PTP device nodes at every reset. To fix this,
break PTP device clock node creation out of i40e_ptp_init, and only call
this if we don't already have a device created. Further invocation of
i40e_ptp_init will not generate new PTP devices. Instead, only the
necessary work required to reconfigure 1588 will be done.

This change also fixes an issue where a reset can cause the
device to forget it's timestamp configuration, and revert to the default
mode.

189464555a i40e: break PTP hardware control from ioctl command for timestamp mode
This patch facilitates future work by breaking the PTP hardware control
bits out of the i40e_set_ts_config function. By doing this, we can
maintain state about the 1588 timestamping mode and properly re-enable
to the last known mode during a re-initialize of 1588 bits.

This patch also modifies i40e_ptp_init to call the
i40e_ptp_set_timestamp_mode during the reconfiguration process. A
future patch will ensure that the hwtstamp_config structure is not reset
during this process, so that timestamp mode will be maintained across a
reset.

When a Tx hang happens, usually the Tx queue disable fails. At
this point if we try to recover by a VSI reinit the HW gets

HW expects a PF reset if a queue disable fails, if we don't do a PF
reset and restart the queue we get an MDD.  This patch makes sure we
do a PF reset on Tx hang and that way we avoid any MDD because of Tx
queue disable failure.

Currently if the firmware reports DCB capability the driver enables
I40E_FLAG_DCB_ENABLED flag. When this flag is enabled the driver
inserts a tag when transmitting a packet from the port even if there
are no DCB traffic classes configured at the port.

This patch adds a new flag I40E_FLAG_DCB_CAPABLE that will be set
when the DCB capability is present and the existing flag
I40E_FLAG_DCB_ENABLED will be set only if there are more than one
traffic classes configured at the port.

them all in the future.

Note that we are just allocating pointers here, the actual (much larger)
VSI structures are allocated on demand.

6374184672 i40e: remove irqs only when they are set up
Use an extra state variable to keep track of when the IRQs are fully
set up.  This keeps us from trying to unhook IRQs that already were
left unhooked in a failed reset recovery, e.g. when firmware is broken.

60442dea2e i40e: don't remove HMC that doesn't exist
If a reset recovery failed (e.g. firmware is broken), the HMC space won't
get set up.  We don't need to try to delete it if it didn't get set up.
This stops some needless error messages when we already know we need to
just tear things down.

Stop printing the netdev multicast value because it doesn't include Tx

d0ff56879a i40e: increase reset wait time
The wait time was originally too optimistic and the resets were failing
after EMPR.  This increases the loop count to wait considerably longer.
This won't delay the actual wait longer than really needed, just allows
us to poll more times as needed.

e03af1e1cb i40e/i40evf: check AQ register for valid data
B0 Si blocks AQ registers when in Blank Flash mode - write is dropped,
read gives 0xDEADBEEF. Introduce a simple check for a correct value in one
of the AQ registers to be sure that AQ was configured correctly.
Without this check we get into an endless loop while trying to send
GetVersion AQ cmd.
