[ Upstream commit a8bf879af7b1999eba36303ce9cc60e0e7dd816c ]
Add the two 1000BaseLX enum values to the X550's check for 1Gbps modules,
allowing the core driver code to establish a link over this SFP type.
This is done by the out-of-tree driver but the fix wasn't in mainline.

[ Upstream commit d14c780c11fbc10f66c43e7b64eefe87ca442bd3 ]
This change makes it so that we are much more explicit about the ordering
of updates to the receive address register (RAR) table. Prior to this patch
I believe we may have been updating the table while entries were still
active, or possibly allowing for reordering of things since we weren't
explicitly flushing writes to either the lower or upper portion of the
register prior to accessing the other half.

commit 0a9a17e3bb4564caf4bfe2a6783ae1287667d188 upstream.
This patch fixes an issue seen on Power systems with ixgbe which results
in skb list corruption and an eventual kernel oops. The following is what
was observed:
CPU 1 CPU2
============================ ============================
1: ixgbe_xmit_frame_ring ixgbe_clean_tx_irq
2: first->skb = skb eop_desc = tx_buffer->next_to_watch
3: ixgbe_tx_map read_barrier_depends()
4: wmb check adapter written status bit
5: first->next_to_watch = tx_desc napi_consume_skb(tx_buffer->skb ..);
6: writel(i, tx_ring->tail);
The read_barrier_depends is insufficient to ensure that tx_buffer->skb does not
get loaded prior to tx_buffer->next_to_watch, which then results in loading
a stale skb pointer. This patch replaces the read_barrier_depends with
smp_rmb to ensure loads are ordered with respect to the load of
tx_buffer->next_to_watch.

A retry count of 10 is likely to run into problems on X550 devices that
have to detect and reset unresponsive CS4227 devices. So, reduce the I2C
retry count to 3 for X550 and above. This should avoid any possible
regressions in existing devices.

[ Upstream commit f7f37e7ff2b9b7eff7fbd035569cab35896869a3 ]
When an interface is part of a namespace it is possible that
ixgbe_close() may be called while __ixgbe_shutdown() is running
which ends up in a double free WARN and/or a BUG in free_msi_irqs().
To handle this situation we extend the rtnl_lock() to protect the
call to netif_device_detach() and ixgbe_clear_interrupt_scheme()
in __ixgbe_shutdown() and check for netif_device_present()
to avoid clearing the interrupts second time in ixgbe_close();
Also extend the rtnl lock in ixgbe_resume() to netif_device_attach().

In the case of IPIP and SIT tunnel frames the outer transport header
offset is actually set to the same offset as the inner transport header.
This results in the lco_csum call not doing any checksum computation over
the inner IPv4/v6 header data.
In order to account for that I am updating the code so that we determine
the location to start the checksum ourselves based on the location of the
IPv4 header and the length.

Jeff Kirsher says:
====================
10GbE Intel Wired LAN Driver Updates 2016-09-23
This series contains updates to ixgbe and ixgbevf.
Emil provides several changes, first simplifies the logic for setting VLAN
filtering by checking the VMDQ flag and the old 82598 MAC, instead of
having to maintain a list of MAC types. Then made two functions static
that are used only within the file, a by-product is sparse is now happy.
Added spinlocks to make sure that the MTU configuration is handled
properly. Fixed an issue where when SR-IOV is enabled while the
ixgbevf driver is loaded would result in all mailbox requests being
rejected by ixgbe, so call ixgbe_sriov_reinit() before pci_enable_sriov()
to ensure mailbox requests are properly handled.
Mark resolves a NULL pointer issue by simply setting the read and write
*_ref_mdi pointers for x550em_a devices. Then clearly indicates within
ethtool that all MACs support pause frames and made sure that the
advertising is set to the requested mode. Fixed an issue where
MDIO_PRTAD_NONE was not being used consistently to indicate no PHY
address.
Alex fixes an issue, where the support for multiple queues when SR-IOV
is enabled was added but the support was not reported. With that, fix
an issue where the hardware redirection table could support more queues
then the PF currently has when SR-IOV is enabled, so use the RSS mask to
trim off the bits that are not used. Lastly, instead of limiting the
VFs if we do not use 4 queues for RSS in the PF, we can instead just limit
the RSS queues used to a power of 2. We can now support use cases where
VFs are using more queues than the PF is currently using and can support
RSS if so desired.

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

Enabling SRIOV while the ixgbevf driver is loaded will result in all
mailbox requests from ixgbevf_open() being rejected by ixgbe because
adapter->clear_to_send is set to false on reset.
Call ixgbe_sriov_reinit() before pci_enable_sriov() to make sure that
mailbox requests are handled from the time ixgbevf is loaded.

Instead of limiting the VFs if we don't use 4 queues for RSS in the PF we
can instead just limit the RSS queues used to a power of 2. By doing this
we can support use cases where VFs are using more queues than the PF is
currently using and can support RSS if so desired.
The only limitation on this is that we cannot support 3 queues of RSS in
the PF or VF. In either of these cases we should fall back to 2 queues in
order to be able to use the power of 2 masking provided by the psrtype
register.

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.

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.

====================
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.

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.

The last check on ret_val is redundant since ret_val has not changed
since the previous check, so remove it as it is extraneous.

The array subscript increments after the execution of the statement.
So there is no issue here. However it helps to read the code better.

I noticed this variable used for register reads wasn't an unsigned
so this patch corrects that. I don't believe this was causing any
issue as is but this is more consistent with the rest of the driver.

The second parameter of these functions is the index to the led we
are interested in affecting. However we were mistakenly passing
the offset in the register. This patch corrects that and adds some
bonds checking which would hopefully make bugs like this more noticeable
in the future.

Currently the function ixgbe_poll() returns 0 when it clean completely
the rx rings, but this foul budget accounting in core code.
Fix this returning the actual work done, capped to weight - 1, since
the core doesn't allow to return the full budget when the driver modifies
the napi status
