TSAUXC.DisableSystime is never set, so SYSTIM runs into a SYS WRAP
every 1100 secs on 80580/i350/i354 (40 bit SYSTIM) and every 35000
secs on 80576 (45 bit SYSTIM).
This wrap event sets the TSICR.SysWrap bit unconditionally.
However, checking TSIM at interrupt time shows that this event does not
actually cause the interrupt. Rather, it's just bycatch while the
actual interrupt is caused by, for instance, TSICR.TXTS.
The conclusion is that the SYS WRAP is actually expected, so the
"unexpected SYS WRAP" message is entirely bogus and just helps to
confuse users. Drop it.

HW timestamping can only be requested for a packet if the NIC is first
setup via ioctl(SIOCSHWTSTAMP). If this step was skipped, then the igb
driver still allowed TX packets to request HW timestamping. In this
situation, the _IGB_PTP_TX_IN_PROGRESS flag was set and would never
clear. This prevented any future HW timestamping requests to succeed.
Fix this by checking that the NIC is configured for HW TX timestamping
before accepting a HW TX timestamping request.

After add an ethertype filter, if user change the adapter speed several
times, the error "ethtool -N: etype filters are all used" is reported by
igb driver.
In older patch, function igb_nfc_filter_exit() and igb_nfc_filter_restore()
is not paried. igb_nfc_filter_restore() exist in igb_up(), but function
igb_nfc_filter_exit() is exist in __igb_close(). In the process of speed
changing, only igb_nfc_filter_restore() is called, it will take a position
of ethertype bitmap.
Reproduce steps:
Step 1: Add a etype filter by ethtool
$ethtool -N eth0 flow-type ether proto 0x88F8 action 1
Step 2: Change the adapter speed to 100M/full duplex
$ethtool -s eth0 speed 100 duplex full
Step 3: Change the adapter speed to 1000M/full duplex
ethtool -s eth0 speed 1000 duplex full
Repeat step2 and step3, then dmesg the system log, you can find the error
message, add new ethtype filter is also failed.
This fixing is move igb_nfc_filter_exit() from __igb_close() to igb_down()
to make igb_nfc_filter_restore()/igb_nfc_filter_exit() is paired.

====================
40GbE Intel Wired LAN Driver Updates 2017-07-25
This series contains updates to i40e and i40evf only.
Gustavo Silva fixes a variable assignment, where the incorrect variable
was being used to store the error parameter.
Carolyn provides a fix for a problem found in systems when entering S4
state, by ensuring that the misc vector's IRQ is disabled as well.
Jake removes the single-threaded restriction on the module workqueue,
which was causing issues with events such as CORER. Does some future
proofing, by changing how the driver displays the UDP tunnel type.
Paul adds a retry in releasing resources if the admin queue times out
during the first attempt to release the resources.
Jesse fixes up references to 32bit timspec, since there are a small set
of errors on 32 bit, so we need to be using the right calls for dealing
with timespec64 variables. Cleaned up code indentation and corrected
an "if" conditional check, as well as making the code flow more clear.
Cast or changed the types to remove warnings for comparing signed and
unsigned types. Adds missing includes in i40evf, which were being used
but were not being directly included.
Daniel Borkmann fixes i40e to fill the XDP prog_id with the id just like
other XDP enabled drivers, so that on dump we can retrieve the attached
program based on the id and dump BPF insns, opcodes, etc back to user
space.
Tushar Dave adds le32_to_cpu while evaluating the hardware descriptor
fields, since they are in little-endian format. Also removed
unnecessary "__packed" to a couple of i40evf structures.
Stefan Assmann fixes an issue when an administratively set MAC was set
and should now be switched back to 00:00:00:00:00:00, the pf_set_mac
flag is not being toggled back to false.

The i40e driver attempts to display the UDP tunnel name by doing a check
against the type, where for non-zero types we use "vxlan" and for zero
type we use "geneve". This is not future proof, because if new tunnel
types get added, we'll incorrectly label them. It also depends on the
value of UDP_TUNNEL_TYPE_GENEVE == 0, which is brittle.
Instead, replace this with a function that can return a constant string
depending on the type. For now we'll use "unknown" for types we don't
know about, and we can expand this in the future if new types get added.

During certain events such as a CORER, multiple devices will run a work
task to handle some cleanup. This can cause issues due to
a single-threaded workqueue which can mean that a device doesn't cleanup
in time. Prevent this by removing the single-threaded restriction on the
module workqueue. This avoids the need to add more complex yielding
logic in our service task routine. This is also similar to what other
drivers such as fm10k do.

Fix incorrect variable assignment.
Based on line 1511: aq_ret = I40_ERR_PARAM; the correct variable to be
used in this instance is aq_ret instead of ret. Also, variable ret is
updated at line 1602 just before return, so assigning a value to this
variable in this code block is useless.

We recently refactored i40e_do_reset() and its friends to be able to
hold the RTNL lock only for the portions that actually need to be
protected. However, a separate refactoring added several new callers of
these functions during the PCIe error recovery and suspend/resume
cycles.
When merging the changes together, it was not noticed that we could
reduce the RTNL scope by letting the reset function handle the lock
itself, as previously it was not possible.
Fix this by replacing these call sites to indicate that the reset
function should handle its own lock. This enables multiple PFs to reset
or resume simultaneously without serializing the resets via the RTNL
lock. The end result is that on systems with lots of PFs and VFs the
resets don't stall waiting for each other to finish.
It is probable that we can also do the same for i40e_do_reset_safe, but
this author did not research that change carefully enough to be
confident.

We should also be checking for the error against the PFINT_ICR0 register,

There exists a bug in which the driver does not correctly exit overflow
promiscuous mode. This can occur if "too many" mac filters are added,
putting the driver into overflow promiscuous mode, and the filters are
then removed. When the failed filters are removed, the driver reports
exiting overflow promiscuous mode which is correct, however traffic
continues to be received as if in promiscuous mode still.
The bug occurs because the conditional for toggling promiscuous mode was
set to only execute when promiscuous mode was enabled and not when it
was disabled as well. This patch fixes the conditional to correctly
execute when promiscuous mode is toggled and not just enabled. Without
this patch, the driver is unable to correctly exit overflow promiscuous
mode.

Partition bandwidth control is not in just one form of MFP (multi-function
partitioning), so make the code more generic and be sure to nudge the Tx
scheduler for all MFP.

Changes parsing of FW 4.33 AQ command Get CEE DCBX OPER CFG (0x0A07).
Change is required because FW now creates the oper_prio_tc
nibbles reversed from those in the CEE Priority Group sub-TLV.
This change will only apply to FW 4.33 as future FW versions will use a
different function to parse the CEE data.

This is a fix for the static code analysis issue where dcbcfg->numapps
could be greater than size of array (i.e dcbcfg->app[I40E_DCBX_MAX_APPS]).
The fix makes sure that the array is not accessed past the size of
of the array (i.e. I40E_DCBX_MAX_APPS).

The firmware expects the port number passed when setting up
the UDP tunnel configuration to be in Little Endian format.
The i40e_aq_add_udp_tunnel command byte swaps the value from
host order to Little Endian.
Since commit fe0b0cd97b4f ("i40e: send correct port number to
AdminQ when enabling UDP tunnels") we've correctly
sent the value in host order.
Let's also add a comment to the function explaining that it must
be in host order, as the port numbers are commonly stored as Big
Endian values.

When searching for the vf_capability client routine, dev_info() was
used, instead of the normal dev_dbg(). This causes the message to be
displayed at standard log levels which can cause administrators to
worry. Avoid this by using dev_dbg instead.
