Suresh Reddy 0b0ef1d027 be2net: do not use frag index in the RX-compl entry
Instead, use the tail of the RXQ to pick the associated RXQ entry

This fix is required in preparation for supporting RXQ lengths greater than 1K.
For such queues, the frag index in the RX-compl entry is not valid as it is only a 10 bit entry not capable of addressing RXQs longer than 1K.

Suresh Reddy 02308d749f be2net: fix incorrect setting of cmd_privileges for VFs
An earlier commit (f25b119c "Fix error messages while driver load for VFs")
incorrectly set the adapter->cmd_privileges value for VFs (in a
multi-channel config) to MAX_PRIVILEGES. This causes FW cmd failures
and avoidable error logs when certian cmds are issued by a VF.
Also, move the multi-channel hack to be_cmds.c inside
be_cmd_get_fn_privileges() routine.

Fixes: f25b119c "Fix error messages while driver load for VFs"

Vasundhara Volam ff32f8abbe be2net: ignore mac-addr set call for an already programmed mac-addr
An ndo_set_mac_addr() call may be issued for a mac-addr that is already
active on an interface. If so, silently ignore the request. Sending such
a request to the FW, causes a "mac collision" error. The error is harmless
but is avoidable noise in the kernel log.

Vasundhara Volam baaa08d148 be2net: do not call be_set/get_fw_log_level() on Skyhawk-R
Skyhawk-R FW does not support SET/GET_EXT_FAT_CAPABILITIES cmds via which
FW logging level can be controlled. Also, the hack used in BE3 to control
FW logging level via the ethtool interface is not needed in Skyhawk-R.

This patch also cleans up this code by moving be_set/get_fw_log_level()
routines to be_cmds.c where they belong.

Greg Rose 99a4973c40 i40e: Warn admin to reload VF driver on port VLAN configuration
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.

Daniel Borkmann 8425783c0f net: vxlan: properly cleanup devs on module unload
We should use vxlan_dellink() handler in vxlan_exit_net(), since
i) we're not in fast-path and we should be consistent in dismantle
just as we would remove a device through rtnl ops, and more
importantly, ii) in case future code will kfree() memory in
vxlan_dellink(), we would leak it right here unnoticed. Therefore,
do not only half of the cleanup work, but make it properly.

Daniel Borkmann acaf4e7099 net: vxlan: when lower dev unregisters remove vxlan dev as well
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
    vxlan id 13 group 239.0.0.10 dev 2 port 32768 61000 ageing 300

Currently, the implementation is meaningless - once again, we take the

However, it's still safe to do this cause we didn't need the
rcu_read_lock() initially - all of the __get_first_agg() callers are either
holding RCU read lock or the RTNL lock, so that we can't sync while in it.

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

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.

Sujith Manoharan 071aa9a8b2 ath9k: Process GTT interrupts
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.

Larry Finger 09164043f6 b43: Fix lockdep splat
In https://bugzilla.kernel.org/show_bug.cgi?id=67561, a locking dependency is reported
when b43 is used with hostapd, and rfkill is used to kill the radio output.

The lockdep splat (in part) is as follows:

======================================================
[ INFO: possible circular locking dependency detected ]
3.12.0 #1 Not tainted
-------------------------------------------------------
rfkill/10040 is trying to acquire lock:
 (rtnl_mutex){+.+.+.}, at: [<ffffffff8146f282>] rtnl_lock+0x12/0x20

but task is already holding lock:
 (rfkill_global_mutex){+.+.+.}, at: [<ffffffffa04832ca>] rfkill_fop_write+0x6a/0x170 [rfkill]

--snip--

Chain exists of:
  rtnl_mutex --> misc_mtx --> rfkill_global_mutex

The fix is to move the initialization of the hardware random number generator
outside the code range covered by the rtnl_mutex.

Luis R. Rodriguez 4f7b91404c cfg80211: make regulatory_hint() remove REGULATORY_CUSTOM_REG
The REGULATORY_CUSTOM_REG can be used during early init with
the goal of overriding the wiphy's default regulatory settings
in case the alpha2 of the device is not known. In the case that
the alpha2 becomes known lets avoid having drivers having to
clear the REGULATORY_CUSTOM_REG flag by doing it for them
when regulatory_hint() is used.

Luis R. Rodriguez 8fc685803a ath: fix warning on usage of REGULATORY_CUSTOM_REG
ath wants to first apply the custom regd and only later
will it revert to not using it if an alpha2 regulatory
domain is found. Since the wireless core now enforces
usage of the REGULATORY_CUSTOM_REG strictly when
wiphy_apply_custom_regulatory() is used this makes
ath adhere to the expected behaviour but also updates
the wiphy after its done with the custom usage.

This fixes this warning:

Emmanuel Grumbach 2775613f4f iwlwifi: mvm: don't set the drain bit when we flush the AP station
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?

====================
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().

In the latest firmware the clear_pxe_mode function will use the
AdminQ request, so call this after AdminQ is set up rather than
relying on i40e_pf_reset() to clear the PXE mode.

Shannon Nelson 8ee75a8ed0 i40e: check for possible incorrect ipv6 checksum
If the IPV6EXADD bit is set in the Rx descriptor status, there
was an optional extension header with an alternate IP address
detected.  The HW checksum offload doesn't handle the alternate
IP address correctly so likely comes up with the wrong answer.
Thus, if the bit is set we ignore the checksum offload value.

Mitch Williams 700bbf6c1f i40e: allow VF to remove any MAC filter
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. This would cause the PF
driver to kick an error message to the log, and back to the VF
driver.

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.

Johannes Berg bc79109896 mac80211_hwsim: allow creating/destroying radios on the fly
Add new commands to the hwsim generic netlink family to allow
creating and destroying radios on the fly. The number of channels
a radio supports can be specified when it's created, if it isn't
the module parameter will be used as default.

This should be extended in the future to allow other parameters
to be specified, e.g.
 * list of channels
 * interface combinations, particularly P2P_DEVICE support
 * regtest
 * and pretty much all other hardware capabilities
