The Tx head write-back registers are not cleared during an FLR or VF reset.
As a result a configuration that had head write-back enabled can leave the
registers set after the driver is unloaded. If the next driver loaded doesn't
use the write-back registers this can lead to a bad configuration where
head write-back is enabled, but the driver didn't request it.
To avoid this situation the PF should be resetting the Tx head write-back
registers when the VF requests a reset.

The bnx2x driver in its pci shutdown() callback releases its pci bars (in the
same manner it does during its pci remove() callback).
During a system reboot while VFs are enabled, its possible for the VF's remove
to be called (as a result of pci_disable_sriov()) after its shutdown callback
has already finished running; This will cause a paging request fault as the VF
tries to access the pci bar which it has previously released, crashing the
system.
This patch further differentiates the shutdown and remove callbacks, preventing the
pci release procedures from being called during shutdown.

The i40e Physical Function (PF) driver will allow the
Virtual Function (VF) driver to configure its own VLAN filters if no port
VLAN filter has been configured. This leads to the possibility of the
administrator setting a port VLAN filter for the VF after the VF has already
configured its own VLAN filters. This leads to a conflict that can only be
resolved by reloading the VF driver. When the conflicting administrative
command is detected in setting the port VLAN then log a message indicating to
the system administrator that he must now reload the VF driver for the new
port VLAN settings to take effect.

We can create a vxlan device with an explicit underlying carrier.
In that case, when the carrier link is being deleted from the
system (e.g. due to module unload) we should also clean up all
created vxlan devices on top of it since otherwise we're in an
inconsistent state in vxlan device. In that case, the user needs
to remove all such devices, while in case of other virtual devs
that sit on top of physical ones, it is usually the case that
these devices do unregister automatically as well and do not
leave the burden on the user.
This work is not necessary when vxlan device was not created with
a real underlying device, as connections can resume in that case
when driver is plugged again. But at least for the other cases,
we should go ahead and do the cleanup on removal.
We don't register the notifier during vxlan_newlink() here since
I consider this event rather rare, and therefore we should not
bloat vxlan's core structure unecessary. Also, we can simply make
use of unregister_netdevice_many() to batch that. fdb is flushed
upon ndo_stop().
E.g. `ip -d link show vxlan13` after carrier removal before
this patch:
5: vxlan13: <BROADCAST,MULTICAST> mtu 1450 qdisc noop state DOWN mode DEFAULT group default
link/ether 1e:47:da:6d:4d:99 brd ff:ff:ff:ff:ff:ff promiscuity 0

Enabling the oscillator consumes slightly more power (100uA)
but allows to make sure that we exit from L1 on time.
Not doing so might lead to a PCIe specification violation
since we might wake up from L1 at the wrong time.
This issue has been identified on 3160 and 7260 only.
On older NICs L1 off is not enabled, on newer NICs (7265),
the issue is fixed.
When the bug occurs the user sees that the NIC has
disappeared from the PCI bridge, any access to the device
returns 0xff.

Global Transmission Timeout interrupts are generated by
the HW when transmission of a frame fails - this is done
based on the threshold programmed in the AR_GTXTO register.
Currently, even though the interrupt is enabled for all chips,
it is not handled in the driver. This patch handles GTT events
for AR9003 and above chips, checking if the MAC/BB has hung
after successive GTT interrupts crosses a threshold (5).
This can be enabled for the older chips in the AR9002 family once
appropriate HW hang checks are implemented for them.

When we disassociate in managed mode, we flush the queues
after mac80211 has already removed the station.
During that time, the pointer to ieee80211_sta to the
fw_id_to_mac_id map is -EINVAL. In that case we should not
set the station as being drained when the last Tx of this
station has exited the shared Tx queue since we are
flushing all the queues anyway.
The draining logic is meant to be used in GO / AP mode only.
In GO / AP mode, we set -EBUSY in the fw_id_to_mac_id map.
This is why testing the ieee80211_sta pointer in the
fw_id_to_mac_id map with IS_ERR isn't enough to set the
station as draining, we need to check that it is -EBUSY.
The only impact of the bug was a print:
Drained sta 1, but it is internal?

If we can't switch to a column because no rates are supported
in that column this led to a state where the search cycle
got stuck and never ended. This in turn also led to aggregation
not being turned on. Fix this by marking a column as

====================
Intel Wired LAN Driver Updates
This series contains updates to i40e and now i40evf.
Most notable is Jacob's patch to add PTP support to i40e.
Mitch cleans up additional memcpy's and use struct assignment instead.
Then fixes long lines to appease checkpatch.pl. Mitch then provides
a fix to keep us from spamming the log with confusing errors. If you
use ip to change the MAC address of a VF while the VF driver is loaded,
closing the VF interface or unloading the VF driver will cause the VF
driver to remove the MAC filter for its original (now invalid) MAC
address.
Jesse cleans up macros which are no longer needed or used.
I (Jeff) cleanup function header comments to ensure Doxygen/kdoc works
correctly to generate documentation without warnings.
Anjali fixes a bug where ethtool set-channels would return failure when
configuring only one Rx queue. Then fixes a bug where the driver was
erroneously exiting the driver unload path if one part of the unload
failed.
Shannon fixes if the IPV6EXADD but is set in the Rx descriptor status,
there was an optional extension header with an alternate IP address
detected and the hardware checksum was not handling the alternate IP
address correctly. Then adjusts the ITR max and min values to match
the hardware max value and recommended min value. Shannon makes sure
to clear the PXE mode after the adminq is initialized.
v2:
- fix patch 14 "i40e: enable PTP" to address Richard Cochran's spelling
catch and Ben Hutchings Kconfig, SIOCGHWTSTAMP and sizeof() suggestions
- added Paul Gortmaker's i40evf fix patch
v3:
- fix patch 14 "i40e: enable PTP" to address Ben Hutchings concerns about
a race with PTP init and cleanup and i40e_get_ts_info().

If the IPV6EXADD bit is set in the Rx descriptor status, there
was an optional extension header with an alternate IP address

IP address correctly so likely comes up with the wrong answer.

If you use ip to change the MAC address of a VF while the VF
driver is loaded, closing the VF interface or unloading the VF
driver will cause the VF driver to remove the MAC filter for its

driver to kick an error message to the log, and back to the VF

Since the VF driver has not really done anything naughty, let's
not punish it. Don't check for MAC address overrides on the
delete operation, just make sure it's a valid address. This keeps
us from spamming the log with confusing errors.

Currently, the tx queue were selected implicitly in ndo_dfwd_start_xmit(). The
will cause several issues:
- NETIF_F_LLTX were removed for macvlan, so txq lock were done for macvlan
instead of lower device which misses the necessary txq synchronization for
lower device such as txq stopping or frozen required by dev watchdog or
control path.
- dev_hard_start_xmit() was called with NULL txq which bypasses the net device
watchdog.
- dev_hard_start_xmit() does not check txq everywhere which will lead a crash
when tso is disabled for lower device.
Fix this by explicitly introducing a new param for .ndo_select_queue() for just
selecting queues in the case of l2 forwarding offload. netdev_pick_tx() was also
extended to accept this parameter and dev_queue_xmit_accel() was used to do l2
forwarding transmission.
With this fixes, NETIF_F_LLTX could be preserved for macvlan and there's no need
to check txq against NULL in dev_hard_start_xmit(). Also there's no need to keep
a dedicated ndo_dfwd_start_xmit() and we can just reuse the code of
dev_queue_xmit() to do the transmission.
In the future, it was also required for macvtap l2 forwarding support since it
provides a necessary synchronization method.

The recent patch to improve guest receive side flow control (ca2f09f2) had a
slight flaw in the wait condition for the vif thread in that any remaining
skbs in the guest receive side netback internal queue would prevent the
thread from sleeping. An unresponsive frontend can lead to a permanently
non-empty internal queue and thus the thread will spin. In this case the
thread should really sleep until the frontend becomes responsive again.
This patch adds an extra flag to the vif which is set if the shared ring
is full and cleared when skbs are drained into the shared ring. Thus,
if the thread runs, finds the shared ring full and can make no progress the
flag remains set. If the flag remains set then the thread will sleep,
regardless of a non-empty queue, until the next event from the frontend.

Starting with commit 80c33dd "net: add might_sleep() call to napi_disable"
bnx2x fails the might_sleep tests causing a stack trace to appear whenever
the driver is unloaded, as local_bh_disable() is being called before
napi_disable().
This changes the locking schematics related to CONFIG_NET_RX_BUSY_POLL,
preventing the need for calling local_bh_disable() and thus eliminating
the issue.

Accessing the current channel definition in mac80211
when processing RX packets is problematic because it
could have been updated when a scan is issued. Since a
channel change involves flushing the existing packets
in the RX queue before a chip-reset is done, they would
be processed using the wrong band/channel information.
To avoid this, use the current channel information
maintained in the driver.

With a dissasociated card I often encoutered very long scan delays.
My guess is that it has something to do with the cards DTIM handling and
another firmware bug mentioned in the TI WLAN driver, which is described as
the card may never end scanning if the channel is overloaded because it
can't send probe requests. I think the firmware somehow also tries to
receive DTIM messages when the BSSID is not set. Therefore most of the time
it waits for DTIM messages and can't do scanning work.
Anyway we can workaround this misbehaviour by setting the HIGH_PRIORITY
bit for scans in disassociated state.
