Commit 5ac6f91d changed the igb driver to expose a zero (empty) mac
address to the VF on reset rather than a random one.
However, that behavioral change also requires igbvf driver changes
which can be hard especially when we want to talk to proprietary
guest OSs.
Looking at the code previous to the commit in Linux that made igbvf
work with empty mac addresses (8d56b6d), we can see that on reset
failure the driver will try to generate a new mac address with both
the old and the new code.
Furthermore, ixgbe does send reset failure when it detects an empty
mac address (35055928c).
So I think it's safe to make igb behave the same. With this patch I
can successfully run a Windows 8.1 guest with an empty mac address
and an assigned igbvf device that has no mac address set by the host.
If anyone is aware of a guest driver that chokes on NACK returns of
VF RESET commands, please speak up.

It also cleans up how we clear the descriptor status bits. Previously they
were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a
64 bit field and 64 bit writes can be a bit more expensive on on 32 bit
systems. Since we are no longer using the header split feature the upper
32 bits of the address no longer need to be cleared. As a result we can
just clear the status bits and leave the length and VLAN fields as-is which
should provide more information in debugging.

Fragmented scan should be applied for all channels, passive and active.
When scanning on passive channels the firmware uses frag_passive_dwell
to define the maximum continuous scan time before returning to the
operating channel. On active channels max_out_time is the parameter
used by the firmware to define the maximum time allowed out of the
operating channel. Since active channels' scan should also be fragmented
set max_out_time equal to frag_passive_dwell.
In addition:
- Set max_out_time and suspend_time if the firmware doesn't support
fragmented scan to avoid unexpected behavior.
- Adjust max_out_time for second level of scan precedence.

* one fix for rfkill while scheduled scan is running.
Linus's system hit this issue. WiFi would be unavailable
after this has happpened because of bad state in cfg80211.
When we have an active scheduled scan, and the RFKILL
interrupt kicks in, the stack will cancel the scheduled
scan as part of the down flow. But cancelling scheduled
scan usually implies sending a command to the firwmare
which has been killed as part of the RFKILL interrupt
handling.
Because of that, we returned an error to mac80211 when
it asked to stop the scheduled scan and didn't notify the
end of the scheduled scan. Besides a fat warning, this led
to a situation in which cfg80211 would refuse any new scan
request.
To disentangle this, fake that the scheduled scan has been
stopped without sending the command to the firwmare, return
0 after having properly let cfg80211 know that the scan
has been cancelled.
This is basically the same as:

Contrary to common expectations for an "int" return, these functions
return only a positive value -- if used correctly they cannot even
return 0 because the message header will necessarily be in the skb.
This makes the very common pattern of
if (genlmsg_end(...) < 0) { ... }
be a whole bunch of dead code. Many places also simply do
return nlmsg_end(...);
and the caller is expected to deal with it.
This also commonly (at least for me) causes errors, because it is very
common to write
if (my_function(...))
/* error condition */
and if my_function() does "return nlmsg_end()" this is of course wrong.
Additionally, there's not a single place in the kernel that actually
needs the message length returned, and if anyone needs it later then
it'll be very easy to just use skb->len there.
Remove this, and make the functions void. This removes a bunch of dead
code as described above. The patch adds lines because I did
- return nlmsg_end(...);
+ nlmsg_end(...);
+ return 0;
I could have preserved all the function's return values by returning
skb->len, but instead I've audited all the places calling the affected
functions and found that none cared. A few places actually compared
the return value with <= 0 in dump functionality, but that could just
be changed to < 0 with no change in behaviour, so I opted for the more
efficient version.
One instance of the error I've made numerous times now is also present
in net/phonet/pn_netlink.c in the route_dumpit() function - it didn't
check for <0 or <=0 and thus broke out of the loop every single time.
I've preserved this since it will (I think) have caused the messages to
userspace to be formatted differently with just a single message for
every SKB returned to userspace. It's possible that this isn't needed
for the tools that actually use this, but I don't even know what they
are so couldn't test that changing this behaviour would be acceptable.

Intel Wired LAN Driver Updates 2015-01-16
This series contains updates to i40e and i40evf.
This series is a little bit larger than normal because two of the patches are
version bumps.
Shannon provides tweaks to i40e and i40evf to keep the firmware, software
and silicon validation in line together by removing unused and
deprecated code, adding define for iSCSI and fix queue mask size. Fix
i40e so we do not give up in the reset/rebuild process if DCB setup
fails, just handle it the same as in the probe setup. Cleans up PTP
log messages by removing the use of __func__ as we are not using that
any longer and removes the netdev name, since that can change and can
be misleading. Adds struct size checks to indirect and command
structs that were left out previously. Added admin queue API updates
(LLDP control, OEM OCSD and OCBB commands).
Kevin increases ASQ timeout for scenarios with multi-function devices.
Carolyn fixes a problem where the interrupts descriptions from the MSIx
configuration were truncating the needed bus info, which makes it hard
to distinguish configurations from port to port. Increased the string
buffer size in order to allow the full data to be displayed.
Sravanthi cleans up the dump stats string from debugfs.
Jacob updates i40e to only enable the PTP interrupt in PFs which have PTP
enabled, instead of blindly enabling the PTP interrupt flags for all PFs.
Also updated i40e so that we do not do Tx or Rx timestamps if we do not
have PTP enabled. Added the same check against pf->ptp_rx as we have
in Rx timestamp code path because it is possible that the user can
configure only Tx hardware timestamping so we do not want to check for
Rx timestamp hang since the software won't be handling them.
Neerav updates the driver to disable firmware LLDP agent for NICs with
a firmware version lower than v4.3 and added a message when this happens.
Adds parsing and reporting of iSCSI capability for a given device or
function, as well as adding support for iSCSI partition type with DCB
in NPAR mode.
v2:
- Dropped patch 10 "i40e: clean up PTP log messages" based on feedback
from David Laight and David Miller
- Split up the original patch 13 "i40e: AQ API updates for new commands"
into 2 patches (now #12 & #13) based on feedback from Or Gerlitz

Add parsing and reporting of iSCSI capability for a given device or
function.
Also add support for iSCSI partition type with DCB in NPAR mode.
In this mode it is expected that software would configure both the LAN
and iSCSI traffic classes for the iSCSI partition; whereas all the NIC
type partitions will use LAN TC (TC0) only.
Hence, the patch enables querying of DCB configuration in MFP mode and
configures TCs for iSCSI partition type.
Though NIC type partitions may not have more than 1 TC enabled for them
the port may have multiple TCs enabled and hence I40E_FLAG_DCB_ENABLED
will be set/reset on all the partitions based on number of TCs on the
port. This is required as in DCB environment it is expected that all
traffic will be priority tagged.

Instead of leaving the Rx timestamps in the same mode as before if we
disable the Rx logic, we can set it into a mode that has the fewest
possible timestamps generated. To do this, select only V1 mode, but do
not enable UDP packet recognition. This should eliminate all (or at
least almost all) Rx timestamps, since V1 packets are always over UDP.

It's possible that the user configured only Tx hardware timestamping,
and thus we might be receiving PTP traffic which we timestamp but which
software never reads. In this case we don't want to check for Rx
timestamp hang, because we already know that software won't be handling
them. Thus, we add the same check against pf->ptp_rx as we have in the
Rx timestamp code path.

Commit 3ba9738134 ("net: ethernet: davinci_emac: add pm_runtime support")
added support for runtime PM, but it causes issues on omap3 related devices
that actually gate the clocks:

Let's fix it by moving the pm_runtime_get() call earlier, and also add it to
the emac_dev_getnetstats(). Also note that we want to use pm_runtime_get_sync()
as we don't want to have deferred_resume happen. And let's also check the
return value for pm_runtime_get_sync() as noted by Felipe Balbi <balbi@ti.com>.

On davinci_emac, we have pulse interrupts. This means that we need to
clear the EOI bits when disabling interrupts as otherwise the interrupts
keep happening. And we also need to not clear the EOI bits again when
enabling the interrupts as otherwise we will get tons of:
unexpected IRQ trap at vector 00
These errors almost certainly mean that the omap-intc.c is signaling
a spurious interrupt with the reserved irq 127 as we've seen earlier
on omap3.
Let's fix the issue by clearing the EOI bits when disabling the
interrupts. Let's also keep the comment for "Rx Threshold and Misc
interrupts are not enabled" for both enable and disable so people
are aware of this when potentially adding more support.
Note that eventually we should handle the RX and TX interrupts
separately like cpsw is now doing. However, so far I have not seen
any issues with this based on my testing, so it seems to behave a
little different compared to the cpsw that had a similar issue.

pull-request: can 2015-01-15
this is a pull request of 8 patches.
Ahmed S. Darwish contributes 4 fixes for the kvaser_usb driver. The two patches
by Oliver Hartkopp mark the m_can driver as non-ISO, as the CANFD standard was
updated. Roger Quadros's patch for the c_can driver fixes the register access
during RAMINIT. And one patch by my, which updates the MAINTAINERS file, as we
