In an effort to improve code readability I am splitting the Flow Director
filter configuration out into a separate function like we have done for the
standard xmit path. The general idea is to provide a single block of code
that translates the flow specification into a proper Flow Director
descriptor.

The Tx cleanup flow was incorrectly assuming it could check for the flow
director bits after it had unmapped the buffer. However in this case it
results in us trying to free a raw_buf as though it is an sk_buff.
To fix this I am moving up the flag test for the FD_SB bit so that when
find a non-NULL skb or raw_buf value we then check the flag and use the
appropriate call to free the buffer.

This patch increases minimum number of allocated VSIs, so as to resolve
failure adding VSI for VF when 64-VFs assigned to a PF. The driver
supports up to 128 VFs per device, users can decide to enable up to
64-VFs on a single PF, especially 2 X 40 devices. In that scenario, with
VMDq co-existence, there would be starvation of VSIs - with this patch,
supported features would have enough VSIs for configuration now.

In i40e_fdir_check_and_reenable(), the driver performs some checks to
determine whether it is safe to re-enable FD Sideband and FD ATR
support. The current check will only determine if there is available
space in the flow director table. However, this ignores the fact that
ATR should be disabled when there are TCP/IPv4 sideband rules in effect.
Add the missing check, and update the info message printed when
I40E_DEBUG_FD is enabled.

Some locations that disable ATR accidentally used the "full" disable by
disabling the flag in the standard flags field. This incorrectly forces
ATR off permanently instead of temporarily disabling it. In addition,
some code locations accidentally set the ATR flag enabled when they only
meant to clear the auto_disable_flags. This results in ignoring the
user's ethtool private flag settings.
Additionally, when disabling ATR via ethtool, we did not perform a flush
of the FD table. This results in the previously assigned ATR rules still
functioning which was not expected.
Cleanup all these areas so that automatic disable uses only the
auto_disable_flag. Fix the flush code so that we can trigger a flush
even when we've disabled ATR and SB support, as otherwise the flush
doesn't work. Fix ethtool setting to actually request a flush. Fix
NETIF_F_NTUPLE flag to only clear the auto_disable setting and not
enable the full feature.

There exists a bug in which deleting a mac filter does not actually
occur. The driver reports that the filter has been deleted with no
error. The problem occurs because the wrong cmd_flag is passed to the
firmware when deleting the filter. The firmware reports an error back
to the driver but it is expressly ignored.
This fixes the bug by using the correct flag when deleting a filter.
Without this patch, deleted filters remain in firmware and function as
if they had not been deleted.

40GbE Intel Wired LAN Driver Updates 2016-09-22
This series contains updates to i40e and i40evf only.
Sridhar fixes link state event handling by updating the carrier and
starts/stops the Tx queues based on the link state notification from PF.
Brady fixes an issue where a user defined RSS hash key was not being
set because a user defined indirection table is not supplied when changing
the hash key, so if an indirection table is not supplied now, then a
default one is created and the hash key is correctly set. Also fixed
an issue where when NPAR was enabled, we were still using pf->mac_seid
to perform the dump port query. Instead, go through the VSI to determine
the correct ID to use in either case.
Mitch provides one fix where a conditional return code was reversed, so
he does a "switheroo" to fix the issue.
Carolyn has two fixes, first fixes an issue in the virt channel code,
where a return code was not checked for NULL when applicable. Second,
fixes an issue where we were byte swapping the port parameter, then
byte swapping it again in function execution.
Colin Ian King fixes a potential NULL pointer dereference.
Bimmy changes up i40evf_up_complete() to be void since it always returns
success anyways, which allows cleaning up of code which checked the
return code from this function.
Alex fixed an issue where the driver was incorrectly assuming that we
would always be pulling no more than 1 descriptor from each fragment.
So to correct this, we just need to make certain to test all the way to
the end of the fragments as it is possible for us to span 2 descriptors
in the block before us so we need to guarantee that even the last 6
descriptors have enough data to fill a full frame.
v2: dropped patches 1-3, 10 and 12 from the original series since Or
Gerlitz pointed out several areas of improvement in the implementation
of the VF Port representor netdev. Sridhar is re-working the series
for later submission.

Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
the ability for user-space application to specify it for the VF, as an
option to support 802.1ad.
We adjusted IP Link tool to support this option.
For future use cases, the new UAPI supports multiple vlans. For now we
limit the list size to a single vlan in kernel.
Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
compatibility with older versions of IP Link tool.
Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
We kept 802.1Q as the drivers' default vlan protocol.
Suitable ip link tool command examples:
Set vf vlan protocol 802.1ad:
ip link set eth0 vf 1 vlan 100 proto 802.1ad
Set vf to VST (802.1Q) mode:
ip link set eth0 vf 1 vlan 100 proto 802.1Q
Or by omitting the new parameter
ip link set eth0 vf 1 vlan 100

The i40e driver was incorrectly assuming that we would always be pulling
no more than 1 descriptor from each fragment. It is in fact possible for
us to end up with the case where 2 descriptors worth of data may be pulled
when a frame is larger than one of the pieces generated when aligning the
payload to either 4K or pieces smaller than 16K.
To adjust for this we just need to make certain to test all the way to the
end of the fragments as it is possible for us to span 2 descriptors in the

When using the debugfs to issue the "dump port" command
with NPAR enabled, the firmware reports back with invalid argument.
The issue occurs because the pf->mac_seid was used to perform the query.
This is fine when NPAR is disabled because the switch ID == pf->mac_seid,
however this is not the case when NPAR is enabled. This fix instead
goes through the VSI to determine the correct ID to use in either case.

Previously, when using ethtool to change the RSS hash key, ethtool would
report back saying the old key was still being used and no error was
reported. It was unclear whether it was being reported incorrectly or
being set incorrectly. Debugging revealed 'i40e_set_rxfh()' returned
zero immediately instead of setting the key because a user defined
indirection table is not supplied when changing the hash key.
This fix instead changes it such that if an indirection table is not
supplied, then a default one is created and the hash key is now
correctly set.

If DCB is configured on the link partner switch with an
unsupported traffic class configuration (e.g. non-contiguous TCs),
the driver is flagging DCB as disabled. But, for future DCB
LLDPDUs, the driver was checking if the interface was DCB capable
instead of enabled. This was causing a kernel panic when LLDP
was enabled/disabled on the link partner switch.
This patch corrects the situation by having the LLDP event handler
check the correct flag in the pf structure. It also cleans up the
setting and clearing of the enabled flag for other checks.
