When NETIF_F_SG is set, each send WQE may have a different size since
each skb can have different number of fragments as of LSO header etc.
This implies that a given WQE may wrap around the send queue, i.e begin
at its end and continue at its start. While it is legal by the device spec,
we preferred a solution that avoids it - when building of current WQE is
done, if the next WQE may wrap around the send queue, fill the send queue
with NOPs WQEs till its end, so that the next WQE will begin at send queue
start.
NOP WQE for itself cannot wrap around the send queue since it is of
minimal size - 64 bytes, and all send WQEs are a multiple of that size.

Ethernet AVB device includes the gPTP timer, so we can implement a PTP clock

calling the PTP driver's [de]initialization and interrupt handler functions.
Unfortunately, the clock seems tightly coupled with the AVB-DMAC, so when that
one leaves the operation mode, we have to unregister the PTP clock... :-(

Ethernet AVB includes an Gigabit Ethernet controller (E-MAC) that is basically
compatible with SuperH Gigabit Ethernet E-MAC. Ethernet AVB has a dedicated
direct memory access controller (AVB-DMAC) that is a new design compared to the
SuperH E-DMAC. The AVB-DMAC is compliant with 3 standards formulated for IEEE
802.1BA: IEEE 802.1AS timing and synchronization protocol, IEEE 802.1Qav real-
time transfer, and the IEEE 802.1Qat stream reservation protocol.
The driver only supports device tree probing, so the binding document is

Intel Wired LAN Driver Updates 2015-06-09
This series contains updates to ixgbe only.
The series adds additional support for x550 support, such as WoL and
auto-negotiation of flow control. Adds new PHY support (external PHY)
for x550, as well as the new methods/functions needed to support the new
PHY's. Fixed a bug found in code inspection, where a check was missed
when clearing counters for x550. Also fixed the init code flow for copper
x550 devices.

As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.
This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.
The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

Reviewing the X550 copper init flow with the Si team resulted in a
new simplified flow. We no longer wait for the PHY FW initialization
complete bit to be set as this bit is only set once by the PHY at power
on and then cleared on the first read. So only the first instance of
running SW (or possibly MAC FW) needs to initialize the PHY.
The PHY initialization has been simplified and now only requires that
the PHY FW be un-stalled
low-power mode or enabled the transceiver

In practice there's no point in having a copy of
chanctx_conf.
Most of the time the channel pointer (and band
along with it) is accessed and this can't change
after a chanctx is created because switching is
done using explicit chanctx swapping via
switch_vif_chanctx().
The only thing that can change within a
chanctx_conf and is used by the driver is
radar_enabled and channel width. These are however
always accessed in adequate mac80211 callback
context which guarantees safe access to the

It seems Broadcom released two devices with conflicting device id. There
are for sure 14e4:4321 PCI devices with BCM4321 (N-PHY) chipset, they
can be found in routers, e.g. Netgear WNR834Bv2. However, according to
Broadcom public sources 0x4321 is also used for 5 GHz BCM4306 (G-PHY).
It's unsure if they meant PCI device id, or "virtual" id (from SPROM).
To distinguish these devices lets check PHY type (G vs. N).

Unfortunately there are also a bit older devices using different way of

Link failures have been observed when using the KSZ9031 with HP 1810-8G
and HP 1910-8G network switches. Center the FLP timing at 16ms to help
avoid intermittent link failures.
>From the KSZ9031RNX and KSZ9031MNX data sheets revision 2.2, section
"Auto-Negotiation Timing":
The KSZ9031[RNX or MNX] Fast Link Pulse (FLP) burst-to-burst
transmit timing for Auto-Negotiation defaults to 8ms. IEEE 802.3
Standard specifies this timing to be 16ms +/-8ms. Some PHY link
partners need to receive the FLP with 16ms centered timing;
otherwise, there can be intermittent link failures and long
link-up times.
The PHY data sheet recommends configuring the FLP burst registers after
power-up/reset and immediately thereafter restarting auto-negotiation, so
we center the FLP timing at 16ms and then restart auto-negotiation in the
config_init for KSZ9031.

The current driver adjust freq formula is:
fe * diff = ppb * pc
Note:
fe: ENET ref clock frequency in Hz
diff = inc_corr - inc: difference between default increment and correction increment
ppb: parts per billion adjustment from base
pc: correction period (in number of fe clock cycles)
The correction increment will be used after N cycles of regular increments,
not every N cycles (with N being the correction period). For example, set ENET_ATCOR=4,
INC=8, INC_CORR=9, there will be 4 increments of 8 (ENET_ATINC[INC]) , followed by 1
increment of 9 (ENET_ATINC[INC_CORR]).
So, the correct formula is:
fe * diff = ppb * (pc + 1)
For ENET_ATCOR, a value 0 disables the correction counter and no corrections occur.
So base on the origin formula, set pc = pc > 1 ? pc - 1 : pc.

The patch fixes a bug in the default configuration which
prevented a software bridge loaded on the PF interface from
working correctly because broadcast packets are incorrectly
looped back.
Fix the general case, by loading the driver in VEPA mode Until a
VF or VMDq VSI is added. This way loopback on the Main VSI is
turned off until needed and can resolve the issue of unnecessary
reflection for users that do not have VF or VMDq VSIs setup.
The driver must now coordinate the loopback setting for the Flow
Director (FDIR) VSI to make sure it is in sync with the current
VEB or VEPA mode setting.
The user can still switch bridge modes from the bridge commands and
choose to be in VEPA mode with VF VSIs. Because of hardware
requirements, the call to switch to VEB mode when no VF/VMDqs are
present will be rejected.
NOTE: This patch uses BIT_ULL as that is preferred going forward,
a followup patch in the lower priority queue to net-next will fix
up the remaining 1 << usages.

Ethernet functionality is only available when working in ISSI > 0 mode.
Previously, the IB driver wasn't ready to work on that mode, and hence
building both the IB driver and the Ethernet functionality in the core
driver were disallowed by Kconfigs.
Now, once we have all the pre-steps in place, we can remove this limitation.
The last steps in the IB driver for getting that setup to work are:
create dummy SRQ for the driver's use (until now we could use XRC_SRQ
as SRQ and XRC_SRQ, after moving to ISSI > 0, we separate XRC SRQs from
basic SRQs) and adapt the create QP function to be compatible with ISSI > 0.

The condition under which the flush should occur was reversed. The fix
should be applied before any HW reset (unless followed by bus reset)
and before any power state transition from D0.
If E1000_FEXTNVM7_NEED_DESCRING_FLUSH bit is set in FEXTNVM7 and TDLEN > 0
the Tx ring should be flushed. (fixes ~95% of the hang states).
If the E1000_FEXTNVM7_NEED_DESCRING_FLUSH did not clear, we should also
flush the RX ring. Bug was caught by Alexander Duyck during a code review

Currently, loading the firmware fails when it has higher API or CAPA
bits than the driver supports. That's an issue with integration.
At the same time, actually using api[0] and capa[0] will become
confusing when we also have api[1] and capa[1], and it's almost
certain that we'll mix up the bits and use the bits for api[1] with
api[0] by accident.
Avoid all this by translating the API/CAPA bits to the regular kernel
test_bit() format, and also providing wrapper functions. Also use the
__bitwise__ facility of sparse to check that we're testing the right
one.

As a preperation for multiple RX queues change the RBD
allocation model.
The new model includes a background allocator. The allocator is
called by the interrupt handler when there are two released
buffers by the queue, and the allocator starts allocating eight
pages per request.
When the queue has released 8 pages it tries claiming the
request. If the pages are not ready - it keeps claiming.
This new model should make sure that RBDs are always available
across the multiple queues.
The RBDs are transferred between the allocator and the queue.
The queue moves the free RBDs upon freeing them to the allocator.
The allocator moves them back to the queue's possession when the
request is claimed.
The allocator has an initial pool to make sure there are always RBDs
available for the request completion.
Release of the buffers at exit is done per pools - the allocator
frees its own initial pool and the queue frees its own pool.
Existing code refactor -
-Queue's initial pool is the size of the queue only as the allocation
of the new buffers no longer uses this pool.
-Removal of replenish background work, and replenish calls in the
interrupt handler and restock().
-The replenish() and the rxq used_list are used only during
initialization.
-Moved page allocation to a new function for code reuse.
New code -
Allocator code - new structure and functions.
Interrupt handler uses the allocator functions for replenishing buffers.
Reuse of the restock() method.

If any VF is assigned as the PF is unloaded, do not attempt to
remove its vport or the vswitch. These will be removed if the
driver binds to the PF again, as an entity reset occurs during
probe.
A 'force' flag is added to efx_ef10_pci_sriov_disable() to
distinguish between disabling SR-IOV and driver unload.
SR-IOV cannot be disabled if VFs are assigned to guests.
If the PF driver is unloaded while VFs are assigned, the driver
may try to bind to the VF again at a later point if the driver
has been reloaded and the VF returns to the same domain as the PF.
In this case, the PF will not have a VF data structure, so the VF
can check this and drop out of probe early.
In this case, efx->vf_count will be zero but VFs will be present.
The user is advised to remove the VF and re-create it. The check
at the beginning of efx_ef10_pci_sriov_disable() that
efx->vf_count is non-zero is removed to allow SR-IOV to be
disabled in this case. Also, if the PF driver is unloaded, it
will disable SR-IOV to remove these unknown VFs.
By not disabling bus-mastering if VFs are still assigned, the VF
will continue to pass traffic after the PF has been removed.
When using the max_vfs module parameter, if VFs are already
present do not try to initialise any more.

When the driver unloads, force the unbind and removal of any
VFs in the host with the PF. The PF cannot remove vports and
vswitches if they are still being used by a VF driver, and when
unloading the sfc driver the removal order is not guaranteed,
so the instruction from the PF to the VF to unbind enforces a
suitable ordering so that vswitches and vports can be removed.
As a result of this, manually unbinding the driver from a single
PF will result in all of its VFs in the host also being removed.

The ifenslave command to set up a bond runs in an atomic

This patch also fixes 64bit mask which should have been ULL by
reworking the node calculation.
