c10ac75aee ixgbe: Do not clear RAR entry when clearing VMDq for SAN MAC
The RAR entry for the SAN MAC address was being cleared when we were
clearing the VMDq pool bits.  In order to prevent this we need to add
an extra check to protect the SAN MAC from being cleared.

22dc13c837 net_sched: convert tcf_exts from list to pointer array
As pointed out by Jamal, an action could be shared by
multiple filters, so we can't use list to chain them
any more after we get rid of the original tc_action.
Instead, we could just save pointers to these actions
in tcf_exts, since they are refcount'ed, so convert
the list to an array of pointers.

The "ugly" part is the action API still accepts list
as a parameter, I just introduce a helper function to
convert the array of pointers to a list, instead of
relying on the C99 feature to iterate the array.

3d951822be ixgbe: Re-enable ability to toggle VLAN filtering
Back when I submitted the GSO code I messed up and dropped the support for
disabling the VLAN tag filtering via the feature bit.  This patch
re-enables the use of the NETIF_F_HW_VLAN_CTAG_FILTER to enable/disable the
VLAN filtering independent of toggling promiscuous mode.

f60439bc21 ixgbe: Force VLNCTRL.VFE to be set in all VMDq paths
When I was adding the code for enabling VLAN promiscuous mode with SR-IOV
enabled I had inadvertently left the VLNCTRL.VFE bit unchanged as I has
assumed there was code in another path that was setting it when we enabled
SR-IOV.  This wasn't the case and as a result we were just disabling VLAN
filtering for all the VFs apparently.

Also the previous patches were always clearing CFIEN which was always set
to 0 by the hardware anyway so I am dropping the redundant bit clearing.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-07-22

This series contains updates to ixgbe and ixgbevf only.

Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where
the index is not equal to zero.  Fixes an issue where mac->ops.setup_fc
can be NULL for backplanes which can cause the driver to crash on load.

Don fixes the second parameter of the LED functions, which is the index to
the LED we are interested in affecting.  Fixed variable to store register
reads to unsigned integer.  Adds support for the new x553 hardware into
ixgbevf.  Fixed a missing rtnl lock around ixgbevf_reinit_locked().
Fixed an issue where in ixgbevf_reset_subtask() was not verifying that
the port has been removed.  Cleans up the initial crosstalk fix, since
the SFP that indicates the presence of a SFP+ module changes between
hardware types.

Babu Moger fixes typo in freeing IRQ, since the array subscript increments
after the execution of the statement.

Wei Yongjun adds the missing destroy_workqueue() before returning from
ixgbe_init_module() in the error handling case.

Tony adds range checking for setting the MTU from the VF, where the PF can
return a NACK but this was not passed on to the VF, so propagate the
results from the PF to the VF so errors can be reported.  Consolidates
mailbox read and write functions, since the recent changes to
ixgbevf_write_msg_read_ack(), other functions are performing the same
operations done here.

Colin Ian King removes a redundant check on ret_val, since ret_val has
not changed since the previous check.

aac9e053f1 ixgbe: cleanup crosstalk fix
This patch address a few issues with the initial crosstalk fix.  Most
important of which is the SDP that indicates the presents of a SFP+
module changes between HW types.  With this change that is taken in
to consideration

It also moves the check closer to the base code that checks link.  This
makes it so we only need to do the check in one spot.

For u32 classifier filters, avoid overwriting existing filter
in a hardware location without removing it first, to clean up
inconsistencies due to duplicate values for filter location.

Create child hash tables:
	handle 1: u32 divisor 1
	handle 2: u32 divisor 1

Link to the child hash table from parent hash table:
	handle 800:0:11 u32 ht 800: link 1: \

b3a49557d5 ixgbe: Replace ndo_add/del_vxlan_port with ndo_add/del_udp_enc_port
This change replaces the network device operations for adding or removing a
VXLAN port with operations that are more generically defined to be used for
any UDP offload port but provide a type.  As such by just adding a line to
verify that the offload type is VXLAN we can maintain the same
functionality.

In addition I updated the socket address family check so that instead of
excluding IPv6 we instead abort of type is not IPv4.  This makes much more
sense as we should only be supporting IPv4 outer addresses on this
hardware.

The last change is that I pulled the rtnl_lock/unlock into the conditional
statement for IXGBE_FLAG2_VXLAN_REREG_NEEDED.  The motivation behind this
is to avoid unneeded bouncing of the mutex which will just slow down the
handling of this call anyway.

vlan_features being setup incorrectly.

This patch corrects that by placing the update of netdev->features to

netdev->features into netdev->vlan_features.

Jeff Kirsher says:

====================
10GbE Intel Wired LAN Driver Updates 2016-05-04

This series contains updates to ixgbe, ixgbevf and traffic class helpers.

Sridhar adds helper functions to the tc_mirred header to access tcf_mirred
information and then implements them for ixgbe to enable redirection to
a SRIOV VF or an offloaded MACVLAN device queue via tc 'mirred' action.

Amritha adds support to set filters with multiple header fields (L3,L4)
to match on.

KY Srinivasan from Microsoft add Hyper-V support into ixgbevf.

Emil adds 82599 sub-device IDs that were missing from the list of parts
that support WoL.  Then simplified the logic we use to determine WoL
support by reading the EEPROM bits for MACs X540 and newer.

Preethi cleaned up duplicate and unused device IDs.  Fixed our ethtool
stat reporting where we were ignoring higher 32 bits of stats registers,
so fill out 64 bit stat values into two 32 bit words.

Babu Moger from Oracle improves VF performance issues on SPARC.

Alex Duyck cleans up some of the Hyper-V implementation from KY so that
we can just use function pointers instead of having to identify if a
given VF is running on a Linux or Windows PF.

Usha makes sure that DCB and FCoE is disabled for X550EM_x/a MACs and
cleans up the DCB initialization in the process.

Tony cleans up the API for ixgbevf_update_xcast_mode() so we do not
have to pass in the netdev parameter, since it was never used in the
function.

4d0e965732 drivers: replace dev->trans_start accesses with dev_trans_start
a trans_start struct member exists twice:
- in struct net_device (legacy)
- in struct netdev_queue

Instead of open-coding dev->trans_start usage to obtain the current
trans_start value, use dev_trans_start() instead.

This is not exactly the same, as dev_trans_start also considers
the trans_start values of the netdev queues owned by the device
and provides the most recent one.

For legacy devices this doesn't matter as dev_trans_start can cope
with netdev trans_start values of 0 (they are ignored).

This is a prerequisite to eventual removal of dev->trans_start.

With this fix, ethtool will report the right queue index even for VFs.
	Action: Direct to queue 4294967296

Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more  user friendly and matches with the 'action' value that
is passed when adding the rule.

4695886c64 ixgbe: fix default mac->ops.setup_link for X550EM
X550EM_a/x did not have a default value for mac->ops.setup_link which
was causing link issues for backplane devices.

This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for
X550EM_a/x which is also default for X550. This will result in
mac->ops.setup_link calling the link setup function for the respective
PHY type in case we do not need a special function to deal with it.

d3dec7c7c0 ixgbe: set VLAN spoof checking unconditionally
Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.

This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.

Also default_vf_vlan_id and vlans_enabled were removed from the
vf_data_storage structure since they are not being used in the driver.

77f192af72 ixgbe: consolidate the configuration of spoof checking
Consolidate the logic behind configuring spoof checking:

Move the setting of the MAC, VLAN and Ethertype spoof checking into
ixgbe_ndo_set_vf_spoofchk().

Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar
to the VLAN and Ethertype functions - this allows us to call the helper
functions in ixgbe_ndo_set_vf_spoofchk() for all spoof check types and
only disable MAC spoof checking when creating MACVLAN.
