07eea570ac ixgbe: Add PF support for VF promiscuous mode
This patch extends the xcast mailbox message to include support for
unicast promiscuous mode.  To allow a VF to enter this mode the PF
must be in promiscuous mode.

A later patch will add the support needed in the VF driver (ixgbevf)

3efa9ed260 ixgbe: Fix issues with EEPROM access
There are two problems with EEPROM access. One is that it needs to
hold the semaphore until the entire response is read or else the
response can be corrupted by other firmware accesses. The second
problem is that acquiring and releasing the semaphore is slow, so
it should be taken and released once when multiple EEPROM accesses
will be done.

Both of these issues can be solved by adding a new function,
ixgbe_hic_unlocked, to issue firmware commands that will assume
that the caller has acquired the needed semaphore.

aeb4c73100 ixgbe: Fix incorrect bitwise operations of PTP Rx timestamp flags
Rx timestamp does not work on 82599 and X540 because bitwise operation
of RX_HWTSTAMP flags is incorrect and ixgbe_ptp_rx_hwtstamp() is never

126db13fa0 ixgbe: fix AER error handling
Make sure that we free the IRQs in ixgbe_io_error_detected() when
responding to an PCIe AER error and also restore them when the
interface recovers from it.

Previously it was possible to trigger BUG_ON() check in free_msix_irqs()
in the case where we call ixgbe_remove() after a failed recovery from
AER error because the interrupts were not freed.

a9d2d53a78 ixgbe: test for trust in macvlan adjustments for VF
There are two methods for setting mac addresses in a Macvlan, that
differentiate themselves in the function macvlan_set_mac_Address.
If the macvlan mode is passthru, then we use the dev_set_mac_address
method, otherwise we use the dev_uc api via macvlan_sync_addresses.
The latter method (which would stem from using any non-passthru mode,
like bridge, or vepa), calls down into the driver in a path that terminates
in ixgbevf_set_uc_addr_vf, which sends a IXGBE_VF_SET_MACVLAN message,
which causes the pf to spawn the noted error message.  This occurs because
it appears that the guest is trying to delete the mac address of the macvlan
before adding another.

The other path in macvlan_set_mac_address uses dev_set_mac_address, which
calls into ixgbevf_set_mac which uses the IXGBE_VF_SET_MAC_ADDR to the
pf to set the macvlan mac address.

The discrepancy here is in the handlers.  The handler function for
IXGBE_VF_SET_MAC_ADDR (ixgbe_set_vf_mac_addr) has a check for
the vfinfo[].trusted bit to allow the operation if the vf is trusted.
In comparison, the IXGBE_VF_SET_MACVLAN message handler
(ixgbe_set_vf_macvlan_msg) has no such check of the trusted bit.

f7f37e7ff2 ixgbe: handle close/suspend race with netif_device_detach/present
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().

2745529ac7 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Couple conflicts resolved here:

1) In the MACB driver, a bug fix to properly initialize the
   RX tail pointer properly overlapped with some changes
   to support variable sized rings.

2) In XGBE we had a "CONFIG_PM" --> "CONFIG_PM_SLEEP" fix
   overlapping with a reorganization of the driver to support
   ACPI, OF, as well as PCI variants of the chip.

3) In 'net' we had several probe error path bug fixes to the
   stmmac driver, meanwhile a lot of this code was cleaned up
   and reorganized in 'net-next'.

4) The cls_flower classifier obtained a helper function in
   'net-next' called __fl_delete() and this overlapped with
   Daniel Borkamann's bug fix to use RCU for object destruction
   in 'net'.  It also overlapped with Jiri's change to guard
   the rhashtable_remove_fast() call with a check against
   tc_skip_sw().

5) In mlx4, a revert bug fix in 'net' overlapped with some
   unrelated changes in 'net-next'.

6) In geneve, a stale header pointer after pskb_expand_head()
   bug fix in 'net' overlapped with a large reorganization of
   the same code in 'net-next'.  Since the 'net-next' code no
   longer had the bug in question, there was nothing to do
   other than to simply take the 'net-next' hunks.

c54cdc316d ixgbe/ixgbevf: Don't use lco_csum to compute IPv4 checksum
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.

9f3c7504fa ixgbe: ixgbe_atr() compute l4_proto only if non-paged data has network/transport headers
For some Tx paths (e.g., tpacket_snd()), ixgbe_atr may be
passed down an sk_buff that has the network and transport
header in the paged data, so it needs to make sure these
headers are available in the headlen bytes to calculate the
l4_proto.

This patch expect that network and transport headers are
already available in the non-paged header dat.  The assumption
is that the caller has set this up if l4_proto based Tx
steering is desired.

b71f6c40bb ixgbe: use link instead of I2C combined abstraction

	read_i2c_combined_unlocked	=> read_link_unlocked
	write_i2c_combined		=> write_link
	write_i2c_combined_unlocked	=> write_link_unlocked

This will allow X550EM_a to override these methods for MDIO access
while X550EM_x provides methods to use I2C combined access. This
also adds a new structure, ixgbe_link_info, to hold information
about the link. Initially this is just method pointers and a bus
address.

The functions involved in combined I2C accesses were moved from
ixgbe_phy.c to ixgbe_x550.c. The underlying functions that carry
out the combined I2C accesses were left in ixgbe_phy.c because
they share some functions with other I2C methods.

91c527a556 ethernet/intel: use core min/max MTU checking
e100: min_mtu 68, max_mtu 1500
- remove e100_change_mtu entirely, is identical to old eth_change_mtu,
  and no longer serves a purpose. No need to set min_mtu or max_mtu
  explicitly, as ether_setup() will already set them to 68 and 1500.

e1000: min_mtu 46, max_mtu 16110

e1000e: min_mtu 68, max_mtu varies based on adapter

fm10k: min_mtu 68, max_mtu 15342
- remove fm10k_change_mtu entirely, does nothing now

i40e: min_mtu 68, max_mtu 9706

i40evf: min_mtu 68, max_mtu 9706

igb: min_mtu 68, max_mtu 9216
- There are two different "max" frame sizes claimed and both checked in
  the driver, the larger value wasn't relevant though, so I've set max_mtu
  to the smaller of the two values here to retain identical behavior.

igbvf: min_mtu 68, max_mtu 9216
- Same issue as igb duplicated

ixgb: min_mtu 68, max_mtu 16114
- Also remove pointless old == new check, as that's done in dev_set_mtu

ixgbe: min_mtu 68, max_mtu 9710

ixgbevf: min_mtu 68, max_mtu dependent on hardware/firmware
- Some hw can only handle up to max_mtu 1504 on a vf, others 9710

5724b8b569 net/sched: tc_mirred: Rename public predicates 'is_tcf_mirred_redirect' and 'is_tcf_mirred_mirror'
These accessors are used in various drivers that support tc offloading,
to detect properties of a given 'tc_action'.

'is_tcf_mirred_redirect' tests that the action is TCA_EGRESS_REDIR.
'is_tcf_mirred_mirror' tests that the action is TCA_EGRESS_MIRROR.

As a prep towards supporting INGRESS redir/mirror, rename these
predicates to reflect their true meaning:
  s/is_tcf_mirred_redirect/is_tcf_mirred_egress_redirect/
  s/is_tcf_mirred_mirror/is_tcf_mirred_egress_mirror/

3eb193e0b2 Merge branch '10GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
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.

79aab093a0 net: Update API for VF vlan protocol 802.1ad support
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

0c339bf9ac ixgbe: reset before SRIOV init to avoid mailbox issues
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.

e24fcf2895 ixgbe: Support 4 queue RSS on VFs with 1 or 2 queue RSS on PF
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.
