43a3d9ba34 i40evf: Allow PF driver to configure RSS
If the PF driver reports proper support, allow the PF driver to
configure RSS on the behalf of the VF driver. This will allow for RSS
support on future hardware without changes to the VF driver.

Unfortunately, the old RSS code still needs to stay as the driver needs
to be compatible with PF drivers that don't support this interface. But
this change still simplifies the data structures a bunch and makes this
code simpler to read and maintain.

c0913c2e43 i40evf: Don't Panic
Under some circumstances the driver remove function may be called before
the driver is fully initialized. So we can't assume that we know where
our towel is at, or that all of the data structures are initialized.

To ensure that we don't panic, check that the vsi_res pointer is valid
before dereferencing it. Then drink beer and eat peanuts.

577389a5db i40e/i40evf: Add support for IPIP and SIT offloads
Looking over the documentation it turns out enabling IPIP and SIT offloads

b0fe330643 i40e/i40evf: Clean up feature flags
The feature flags list for i40e and i40evf is beginning to become pretty
massive.  I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.

The primary change here is that we now build our features list around
hw_encap_features.  After that we assign that to vlan_features,
hw_features, and finally map that onto features.  In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC.  However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.

For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense.  I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so
disabling it is just a matter of ignoring the result from the hardware.

d4f90d9dca ixgbe: use msleep for long delays
The newly added x550em_a support causes a link failure on ARM because of
an overly long time passed into udelay():

ERROR: "__bad_udelay" [drivers/net/ethernet/intel/ixgbe/ixgbe.ko] undefined!

There are multiple variants of the ixgbe_acquire_swfw_sync_*() function,
and the other ones all use msleep(), so we can safely assume that all
callers are allowed to sleep, which makes msleep() a better replacement
than mdelay().

so we can avoid changes in one breaking something in the other.

b4f47a4830 ixgbe: use BIT() macro
Several areas of ixgbe were written before widespread usage of the
BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.

Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

2a9ed5d1fc ixgbe: make 'action' field in struct ixgbe_fdir_filter a u64 value
This field is used to record the RX queue index for a redirect action
passed via ring_cookie field in struct ethtool_rx_flow_spec which is
a u64 value.

For ex: after adding a filter rule to redirect to a VF using ethtool
  # echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
  # ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000

querying for the rule shows the Action as 'Direct to queue 0'

  # ethtool -n p4p1
  4 RX rings available
  Total 1 rules

  Filter: 2045
 	Rule Type: Raw IPv4
	Src IP addr: 192.168.0.1 mask: 0.0.0.0
	Dest IP addr: 0.0.0.0 mask: 255.255.255.255
	TOS: 0x0 mask: 0xff
	Protocol: 0 mask: 0xff
	L4 bytes: 0x0 mask: 0xffffffff
	VLAN EtherType: 0x0 mask: 0xffff
	VLAN: 0x0 mask: 0xffff
	User-defined: 0x0 mask: 0xffffffffffffffff
	Action: Direct to queue 0

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.

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.

3417415c3a fm10k: do not disable PCI device in fm10k_io_error_detected
fm10k_io_error_detected() does not need to call pci_disable_device(). In
the cases where the reset needs to occur, the stack flow will result in
calling fm10k_remove() which already disables the PCI device. If we
leave the pci_disable_device(), we result in a warning about disabling
an already disabled device.

Many PCI drivers do call pci_disable_device() in their .error_detected()
routines, but it does not appear to be required. In addition, these
drivers have a check "is_pci_enabled()" call in their remove routines,
which is how they chose to handle the duplicate device disable.

This seems incorrect, since the PCI device structure is reference
counted. It is very possible that the reference count for the PCI device
could be greater than 1. In this case, you would remove the PCI device
within the error_detected routine, reducing count to 1, then remove it
again in the remove function, reducing it to zero. This would result in
yet another disable somewhere else failing. Thus, we shouldn't be using
is_pci_enabled() to check for this issue. Instead, just remove the
extraneous pci_device_disable() found within the error_detected routine.

a7a7783ada fm10k: correctly handle LPORT_MAP error
Currently, any error responses from the switch manager after an
LPORT_MAP request are silently ignored. At most the mailbox message will
be reported as an error. This can result in unexpected behavior when the
switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.

If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.

The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

8998763a7b fm10k: Fix multicast mode sync issues
Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.

Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

f808c5dbcd fm10k: fix multi-bit VLAN update requests from VF
The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refector broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set.

We can't simply remove the check of the upper 16 bits and the call to
fm10k_iov_select vid, because this would remove the checks for default
VID and for ensuring no other VLANs can be enabled except pf_vid when it
has been set. To resolve that issue, this revision uses the
iov_select_vid when we have a single-bit update, and denies any
multi-bit update when the VLAN was administratively set by the PF. This
should be ok since the PF properly updates VLAN_TABLE when it assigns
the PF vid. This ensures that requests to add or remove the PF vid work
as expected, but a rogue VF could not use the multi-bit update as
a loophole to attempt receiving traffic on other VLANs.

3f3f7cb875 i40e/i40evf: Limit TSO to 7 descriptors for payload instead of 8 per packet
This patch addresses a bug introduced based on my interpretation of the
XL710 datasheet.  Specifically section 8.4.1 states that "A single transmit
packet may span up to 8 buffers (up to 8 data descriptors per packet
including both the header and payload buffers)."  It then later goes on to
say that each segment for a TSO obeys the previous rule, however it then
refers to TSO header and the segment payload buffers.

I believe the actual limit for fragments with TSO and a skbuff that has
payload data in the header portion of the buffer is actually only 7
fragments as the skb->data portion counts as 2 buffers, one for the TSO
header, and one for a segment payload buffer.

1GbE Intel Wired LAN Driver Updates 2016-04-06

This series contains updates to e1000, e1000e, igb and Kconfig.

Alex fixes igb where we were casting the MAC address as __beXX and then
passing it into le32_to_cpu, when we could simply cast as __lexx to
maintain consistency since it is already little endian.  Then enabled
bulk free in transmit cleanup for igb.

John Holland enables igb to pickup the MAC address from a device tree
blob when CONFIG_OF has been enabled.

Doron Shikmoni fixes a bug in the output of "ethtool -m ethX" where
the data byte appeared duplicated.

Stefan fixes up e1000 and e1000e ethtool offline tests which were calling
dev_close() which causes IFF_UP to be cleared which removes teh interface
routes and some addresses, so use ndo_stop() instead.

Jiri Benc cleans up some old links in the Kconfig for Intel drivers where
we referred to a URL which is no longer valid.  I am so glad Jiri has the
time in his day to spend clicking on and testing all the URL links in the
the kernel.

As it turns out, calling into other files from hot path hurts
performance a lot.  In this case the majority of the time we
call "check FCoE" and the packet is *not* FCoE, but this call
was taking 5% of our total cycles spent on receive.

1f2f83f838 e1000: call ndo_stop() instead of dev_close() when running offline selftest
Calling dev_close() causes IFF_UP to be cleared which will remove the
interfaces routes and some addresses. That's probably not what the user
intended when running the offline selftest. Besides this does not happen
if the interface is brought down before the test, so the current
behaviour is inconsistent.
Instead call the net_device_ops ndo_stop function directly and avoid
touching IFF_UP at all.

efea95d45e igb: Garbled output for "ethtool -m"
Garbled output for "ethtool -m ethX", in igb-driven NICs with module /
plugin EEPROM (i.e. SFP information). Each output data byte appears
duplicated.

In igb_ethtool.c, igb_get_module_eeprom() is reading the EEPROM via i2c;
the eeprom offset for each word that's read via igb_read_phy_reg_i2c()
was passed in #words, whereas it needs to be a byte offset.
This patches fixes the bug.

because the device expects the MAC address to be in network order even
though the register set is little endian.  Instead of casting it as __beXX
we can just cast it as __leXX in order to maintain consistency since the

concerned.
