a3d772a392 i40e: fix write-back-on-itr to work with legacy itr
We were not doing write-back on interrupt throttle for Legacy case in X722.
This patch fixes that, so we do WB_ON_ITR for Legacy as well. Plus the issue
that we should still be setting NO_ITR if we are touching the DYN_CTLN register
since we do not want to change ITR setting here.

6e35c04cf6 i40e/i40evf: Fix RSS rx-flow-hash configuration through ethtool
This patch fixes the Hash PCTYPE enable for X722 since it supports
a broader selection of PCTYPES for TCP and UDP.

This patch also fixes a bug in XL710, X710, X722 support for RSS,
as of now we cannot reduce the (4)tuple for RSS for TCP/IPv4/IPV6 or
UDP/IPv4/IPv6 packets since this requires a product feature change
that comes in a later release.

A VF should never be allowed to change the tuples for RSS for any
PCTYPE since that's a global setting for the device in case of i40e
devices.

857942fd1a i40e: Fix Rx hash reported to the stack by our driver
If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded

on our device.

This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

b499ffb0a2 i40e: Look up MAC address in Open Firmware or IDPROM
This is the i40e equivalent of commit c762dff24c ("ixgbe: Look up MAC
address in Open Firmware or IDPROM").

As with that fix, attempt to look up the MAC address in Open Firmware
on systems that support it, and use IDPROM on SPARC if no OF address
is found.

In the case of the i40e there is an assumption that the default mac
address has already been set up as the primary mac filter on probe,
so if this filter is obtained from the Open Firmware or IDPROM, an
explicit write is needed via i40e_aq_mac_address_write() and
i40e_aq_add_macvlan() invocation.

The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure
tracks whether a platform-specific mac address was found, in which
case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan()
will be triggered.

a188222b6e net: Rename NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK
The name NETIF_F_ALL_CSUM is a misnomer. This does not correspond to the
set of features for offloading all checksums. This is a mask of the
checksum offload related features bits. It is incorrect to set both
NETIF_F_HW_CSUM and NETIF_F_IP_CSUM or NETIF_F_IPV6 at the same time for
features of a device.

This patch:
  - Changes instances of NETIF_F_ALL_CSUM to NETIF_F_CSUM_MASK (where
    NETIF_F_ALL_CSUM is being used as a mask).
  - Changes bonding, sfc/efx, ipvlan, macvlan, vlan, and team drivers to

f11999987b i40e: clean whole mac filter list
Clean the whole mac filter list when resetting after an intermediate
add or delete push to the firmware.  The code had evolved from using
a list from the stack to a heap allocation, but the memset() didn't
follow the change correctly.  This now cleans the whole list rather
that just part of the first element.

b9eacec3e6 i40e/i40evf: Add a new offload for RSS PCTYPE V2 for X722
X722 supports Expanded version of TCP, UDP PCTYPES for RSS.
Add a Virtchnl offload to support this.

Without this patch with X722 devices, driver will set wrong PCTYPES
for VF and UDP flows will not fan out.

75eb73c127 i40e: hush little warnings
These messages seem big and scary, but they're really not. The driver
can fully recover from any of these. The overflow error in particular
can happen when enabling a bunch of VFs and the VF driver is not
blacklisted.

Since these messages are really for debugging purposes, reclassify
them as such.

00ada50d89 i40e: Opcode and structures required by OEM Post Update AQ command and add new NVM arq message
This is a part of implementation which contains data structures and
opcode for new AQ command. There's a new ARQ message that gets sent
near the end of the NVM update process that the driver should recognize
and ignore, rather than printing an Unknown Event error.

b7b713a8ea i40e: don't add zero MAC filter
When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.

Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.

b36e9ab59b i40e: properly delete VF MAC filters
The virtual channel interface was using incorrect semantics to remove
MAC addresses, which would leave incorrect filters active when using
VLANs. To correct this, add a new function that unconditionally removes
MAC addresses from all VLANs, and call this function when the VF
requests a MAC filter removal.

This reverts commit 8fe269991a.
The case where VXLAN is a module and i40e driver is inbuilt
will not be handled properly with this change since i40e
will have an undefined symbol vxlan_get_rx_port in it.

8ddb332689 i40e/i40evf: avoid mutex re-init
If the driver were to happen to have a mutex held while
the i40e_init_adminq call was called, the init_adminq might
inadvertently call mutex_init on a lock that was held
which is a violation of the calling semantics.

Fix this by avoiding adminq.c code allocating/freeing this memory, and
then do the same work only once in probe/remove.

Testing Hints (Required if no HSD): for VF, load i40evf in bare metal
and echo 32 > sriov_numvfs; echo 0 > sriov_numvfs in a loop.  Yes this
is a horrible thing to do.

f4f7981ed3 Merge branch '40GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says:

====================
40GbE Intel Wired LAN Driver Updates 2015-12-03

This series contains updates to i40e and i40evf only.

Mitch updates the i40evf driver by increasing the maximum number of queues,
since future devices will allow for more queue pairs.  Cleans up a
duplicate printing of the driver info string done in init, since it is
already done in probe.  Cleaned up the several allocations which did
not need to be at atomic level, where GFP_KERNEL would work just fine.
Then makes i40e_sync_vsi_filters() a more mature function, make having
a common exit point so it will properly release the busy lock on the VSI
and propagate errors to the callers.  Then does some whitespace
housekeeping in i40evf.

Kiran moves and updates the detection/recovery of transmit queue hang code
to service_task from tx_timeout function.  Also fixed memory leak when
users program flow-director filter using ethtool (sideband filter
programming), the cause being the check of 'tx_buffer->skb' was preventing
'raw_buf' from being freed as part of the cleanup.

Jesse enabled the ability to turn off/on packet split using ethtool priv
flags.  Then does some housekeeping for both the i40e and i40evf drivers
which includes: remove unused/useless code, correct whitespace, remove
duplicate #include, fix incorrect comment, etc...

Neerav cleans up functions to gather Flow Control Rx XOFF stats, since
the recent change in the driver logic for checking transmit hang has been
moved, so these functions do not do anything meaningful any longer.

3b195843f5 i40e: Fix i40e_print_features() VEB mode output
Commit 7fd89545f3 ("i40e: remove BUG_ON from feature string building")
added defective output when I40E_FLAG_VEB_MODE_ENABLED was set in
function i40e_print_features.

Fix it.

Miscellanea:

- Remove unnecessary string variable
- Add space before not after fixed strings
- Use kmalloc not kzalloc
- Don't initialize i to 0, use result of first snprintf
