37a622c193 i40evf: Rename i40e_ptype_lookup i40evf_ptype_lookup
When compiling the i40e and the i40evf driver into the same kernel I get:
LD      drivers/net/ethernet/intel/built-in.o
drivers/net/ethernet/intel/i40evf/built-in.o:(.data+0x300): multiple definition of `i40e_ptype_lookup'
drivers/net/ethernet/intel/i40e/built-in.o:(.data+0x780): first defined here

make[2]: *** [drivers/net/ethernet/intel] Error 2
make[1]: *** [drivers/net/ethernet/] Error 2
make: *** [sub-make] Error 2

Fix this by renaming the i40evf version of this structure from
i40e_ptype_lookup to i40evf_ptype_lookup.

This build failure was introduced in:

We need a hard irq safe variant to deal with netpoll transmitting

the places using the bh safe variant.

Except on 32bit uni-processor the code is exactly the same so don't
bother with a bh variant, just have a hard irq safe variant that
everyone can use.

The PF has always reported the correct number of MSI-X vectors, so we

Checking it like if it was a bitmask of values would also cause
PACKET_OTHERHOST, PACKET_LOOPBACK and PACKET_FASTROUTE to be matched by
this check since their lower 2 bits are also set, although that does not
fix a real bug, it is still potentially confusing.

96dee024ca e1000e: Fix SHRA register access for 82579
Previous commit c3a0dce35a fixed an overrun for the RAR on i218 devices.
This commit also attempted to homogenize the RAR/SHRA access for all parts
accessed by the e1000e driver.  This change introduced an error for
assigning MAC addresses to guest OS's for 82579 devices.

Only RAR[0] is accessible to the driver for 82579 parts, and additional
addresses must be placed into the SHRA[L|H] registers.  The rar_entry_count
was changed in the previous commit to an inaccurate value that accounted
for all RAR and SHRA registers, not just the ones usable by the driver.

This patch fixes the count to the correct value and adjusts the
e1000_rar_set_pch2lan() function to user the correct index.

5bb7317608 e1000e: Fix not generating an error on invalid load parameter
Valid values for InterruptThrottleRate are 10-100000, or one of
0, 1, 3, 4.  '2' is not valid.  This is a legacy from the branching
from the e1000 driver code that e1000e was based from.

Prior to this patch, if the e1000e driver  was loaded with a forced
invalid InterruptThrottleRate of '2', then no throttle rate would be
set and no error message generated.

Now, a message will be generated that an invalid value was used and the
value for InterruptThrottleRate will be set to the default value.

74f350ee08 e1000e: Feature Enable PHY Ultra Low Power Mode (ULP)
ULP is a power saving feature that reduces the power consumption of the
PHY when a cable is not connected.

ULP is gated on the following conditions:
1) The hardware must support ULP.  Currently this is only I218
   devices from Intel
2) ULP is initiated by the driver, so, no driver results in no ULP.
3) ULP's implementation utilizes Runtime Power Management to toggle its
   execution.  ULP is enabled/disabled based on the state of Runtime PM.
4) ULP is not active when wake-on-unicast, multicast or broadcast is active
   as these features are mutually-exclusive.

Since the PHY is in an unavailable state while ULP is active, any access
of the PHY registers will fail.  This is resolved by utilizing kernel
calls that cause the device to exit Runtime PM (e.g. pm_runtime_get_sync)
and then, after PHY access is complete,  allow the device to resume
Runtime PM (e.g. pm_runtime_put_sync).

Under certain conditions, toggling the LANPHYPC is necessary to disable
ULP mode.  Break out existing code to toggle LANPHYPC to a new function
to avoid code duplication.

2800209994 e1000e: Refactor PM flows
Refactor the system power management flows to prevent the suspend path from
being executed twice when hibernating since both the freeze and
poweroff callbacks were set to e1000_suspend() via SET_SYSTEM_SLEEP_PM_OPS.
There are HW workarounds that are performed during this flow and calling
them twice was causing erroneous behavior.

Re-arrange the code to take advantage of common code paths and explicitly
set the individual dev_pm_ops callbacks for suspend, resume, freeze,
thaw, poweroff and restore.

Add a boolean parameter (reset) to the e1000e_down function to allow
for cases when the HW should not be reset when downed during a PM event.

Now that all suspend/shutdown paths result in a call to __e1000_shutdown()
that checks Wake on Lan status, removing redundant check for WoL in
e1000_power_down_phy().

f7235ef669 e1000e: Resolve issues with Management Engine (ME) briefly blocking PHY resets
On a ME enabled system with the cable out, the driver init flow would
generate an erroneous message indicating that resets were being blocked
by an active ME session.  Cause was ME clearing the semaphore bit to
block further PHY resets for up to 50 msec during power-on/cycle.  After
this interval, ME would re-set the bit and allow PHY resets.

To resolve this, change the flow of e1000e_phy_hw_reset_generic() to
utilize a delay and retry method.  Poll the FWSM register to minimize
any extra time added to the flow.  If the delay times out at 100ms
(checked in 10msec increments), then return the value E1000_BLK_PHY_RESET,
as this is the accurate state of the PHY.  Attempting to alter just the
call to e1000e_phy_hw_reset_generic() in e1000_init_phy_workarounds_pchlan()
just caused the problem to move further down the flow.

d773ce2de1 ixgbe: modify behavior on receiving a HW ECC error.
Currently when we noticed a HW ECC error we would request the use reload
the driver to force a reset of the part.  This was done due to the mistaken
believe that a normal reset would not be sufficient.  Well it turns out it
would be so now we just schedule a reset upon seeing the ECC.

99932d4fc0 netdevice: add queue selection fallback handler for ndo_select_queue
Add a new argument for ndo_select_queue() callback that passes a
fallback handler. This gets invoked through netdev_pick_tx();
fallback handler is currently __netdev_pick_tx() as most drivers
invoke this function within their customized implementation in
case for skbs that don't need any special handling. This fallback
handler can then be replaced on other call-sites with different
queue selection methods (e.g. in packet sockets, pktgen etc).

This also has the nice side-effect that __netdev_pick_tx() is
then only invoked from netdev_pick_tx() and export of that
function to modules can be undone.

ef8693eb90 i40evf: refactor reset handling
Respond better to a VF reset event. When a reset is signaled by the
PF, or detected by the watchdog task, prevent the watchdog from
processing admin queue requests, and schedule the reset task.

In the reset task, wait first for the reset to start, then for it to
complete, then reinit the driver.

If the reset never appears to complete after a long, long time (>10
seconds is possible depending on what's going on with the PF driver),
then set a flag to indicate that PF communications have failed.

If this flag is set, check for the reset to complete in the watchdog,
and  attempt to do a full reinitialization of the driver from scratch.

With these changes the VF driver correctly handles a PF reset event
while running on bare metal, or in a VM.

Also update copyrights.

as u32 (since we don't need any more than about a dozen flags right
now), and remove the volatile qualifier, since it's unnecessary and
just makes checkpatch cry.

In addition this patch makes tx_flags part of the ixgbevf_tx_buffer struct.
This allows us to use the flags directly from the stucture and as result
removes the tx_flags parameter from some functions. Also as a cleanup
mapped_as_page is folded into tx_flags and some unused flags were removed.

4e3b35b044 i40e: add DCB and DCBNL support
This patch adds capability to configure DCB on i40e network
interfaces using Intel XL710 adapter firmware APIs.

By default all VSIs are only enabled for the default traffic
class enabled by firmware for any given PF. The driver would
query the firmware for the traffic classes that are enabled for
the port and reconfigure the LAN VSI to match to the port traffic
class settings. All other VSIs are only enabled for the default
traffic class settings for now.

The driver registers and listens to firmware events that may
require change in the DCB settings. It may reconfigure the VSI
settings based on these events.

This patch exposes IEEE DCBNL interfaces for the i40e driver to
allow any application to query the DCB settings on the adapter.

afb3ff0da4 i40e: implement DCB support infastructure
Intel XL710 series of adapters support QoS as per the
IEEE 802.1 DCB (Data Center Bridging) standard.
This is supported in conjuction with:
- Enhanced Transmission Selection (ETS) - IEEE 802.1Qaz
- Priority Flow Control (PFC) - IEEE 802.1Qbb
- DCB eXchange Protocol (DCBX) - IEEE 802.1Qaz

On Intel XL710 adapters DCBX is performed by the adapter
firmware. The firmware runs DCBX in willing mode and configures
the port as per the DCB settings recommended by it's link
partner.

By default in absence of any DCBX; firmware would configure the
port with a single traffic class and all of the port bandwith
will be allocated to that traffic class.

This patch adds functions and calls to support querying and
configuring DCB using firmware APIs.

dcc23e3ab6 ixgbe: define IXGBE_MAX_VFS_DRV_LIMIT macro and cleanup const 63
Because ixgbe driver limit the max number of VF
 functions could be enabled to 63, so define one macro IXGBE_MAX_VFS_DRV_LIMIT
 and cleanup the const 63 in code.

v3: revised for net-next tree.

so as to be easier to read and not abusing the types and unions.

38a529b5d4 e1000e: Fix compilation warning when !CONFIG_PM_SLEEP
Commit 7509963c70 (e1000e: Fix a compile flag mis-match for
suspend/resume) moved suspend and resume hooks to be available when
CONFIG_PM is set. However, it can be set even if CONFIG_PM_SLEEP is not set
causing following warnings to be emitted:

drivers/net/ethernet/intel/e1000e/netdev.c:6178:12: warning:
  	‘e1000_suspend’ defined but not used [-Wunused-function]

drivers/net/ethernet/intel/e1000e/netdev.c:6185:12: warning:
	‘e1000_resume’ defined but not used [-Wunused-function]

To fix this make the hooks to be available only when CONFIG_PM_SLEEP is set
and remove CONFIG_PM wrapping from driver ops because this is already
handled by SET_SYSTEM_SLEEP_PM_OPS() and SET_RUNTIME_PM_OPS().

de02decb33 ixgbevf: create function for all of ring init
This patch creates new functions for ring initialization,
ixgbevf_configure_tx_ring() and ixgbevf_configure_rx_ring(). The work done
in these function previously was spread between several other functions and
this change should hopefully lead to greater readability and make the code
more like ixgbe.  This patch also moves the placement of some older functions
to avoid having to write prototypes.  It also promotes a couple of debug
messages to errors.

87e70ab908 ixgbevf: Convert ring storage form pointer to an array to array of pointers
This will change how we store rings arrays in the adapter sturct.
We use to have a pointer to an array now we will be using an array
of pointers.  This will allow us to support multiple queues on
muliple nodes at some point we would be able to reallocate the rings
so that each is on a local node if needed.

e689e72823 ixgbevf: set the disable state when ixgbevf_qv_disable is called
The ixgbevf_qv_disable function used by CONFIG_NET_RX_BUSY_POLL is broken,
because it does not properly set the IXGBEVF_QV_STATE_DISABLED bit, indicating
that the q_vector should be disabled (and preventing future locks from
obtaining the vector). This patch corrects the issue by setting the disable
state.

8f4c5c9fb8 ixgbe: reinit_locked() should be called with rtnl_lock
ixgbe_service_task() is calling ixgbe_reinit_locked() without
the rtnl_lock being held. This is because it is being called
from a worker thread and not a rtnl netlink or dcbnl path.

Add rtnl_{un}lock() semantics. I found this during code review.

a81ab36bf5 drivers/net: delete non-required instances of include <linux/init.h>
None of these files are actually using any __init type directives
and hence don't need to include <linux/init.h>.   Most are just a
left over from __devinit and __cpuinit removal, or simply due to
code getting copied from one driver to the next.

This covers everything under drivers/net except for wireless, which
has been submitted separately.

dbf231af81 ixgbe: Clear head write-back registers on VF reset
The Tx head write-back registers are not cleared during an FLR or VF reset.
As a result a configuration that had head write-back enabled can leave the
registers set after the driver is unloaded.  If the next driver loaded doesn't
use the write-back registers this can lead to a bad configuration where
head write-back is enabled, but the driver didn't request it.

To avoid this situation the PF should be resetting the Tx head write-back
registers when the VF requests a reset.
