VID 1 is not reserved anymore, so remove the check that prevented the
creation of VLAN devices with this VID over mlxsw ports.

There is no need to abuse VID 1 anymore and we can instead use VID 4095
as the default VLAN, which will be configured on the port throughout its
lifetime.
The OVS join / leave functions are changed to enable VIDs 1-4094
(inclusive) instead of 2-4095. This because VID 4095 is now the default
VLAN instead of 1.

VLAN entries on a port can be associated with either a bridge VLAN or a
router port. Before the VLAN entry is destroyed these associations need
to be cleaned up.
Currently, this is always invoked from the function which destroys the
VLAN entry, but next patch is going to skip the destruction of the
default entry when a port in unlinked from a LAG.
The above does not mean that the associations should not be cleaned up,
so add a helper that will be invoked from both call sites.

Subsequent patches will need to access the default port VLAN. Since this
VLAN will exist throughout the lifetime of the port, simply store it in
the port's struct.

The function allows flushing all the existing VLAN entries on a port. It
is invoked when a port is destroyed and when it is unlinked from a LAG.
In the latter case, when moving to the new default VLAN, there will not
be a need to destroy the default VLAN entry.
Therefore, add an argument that allows to control whether the default
port VLAN should be destroyed or not. Currently it is always set to
'true'.

Currently, the driver does not set the port's PVID when initializing a
new port. This is because the driver is using VID 1 as PVID which is the
firmware default.
Subsequent patches are going to change the PVID the driver is setting
when initializing a new port.
Prepare for that by explicitly setting the port's PVID.

In symmetric routing, the only two members in the VLAN corresponding to
the L3 VNI are the router port and the VXLAN tunnel.
In case the VXLAN device is already enslaved to the bridge and only
later the VLAN interface is configured, the tunnel will not be
offloaded.
The reason for this is that when the router interface (RIF)
corresponding to the VLAN interface is configured, it calls the core
fid_get() API which does not check if NVE should be enabled on the FID.
Instead, call into the bridge code which will check if NVE should be
enabled on the FID.
This effectively means that the same code path is used to retrieve a FID
when either a local port or a router port joins the FID.

Jeff Kirsher says:
====================
Intel Wired LAN Driver Updates 2018-12-20
This series contains updates to e100, igb, ixgbe, i40e and ice drivers.
I replaced spinlocks for mutex locks to reduce the latency on CPU0 for
igb when updating the statistics. This work was based off a patch
provided by Jan Jablonsky, which was against an older version of the igb
driver.
Jesus adjusts the receive packet buffer size from 32K to 30K when
running in QAV mode, to stay within 60K for total packet buffer size for
igb.
Vinicius adds igb kernel documentation regarding the CBS algorithm and
its implementation in the i210 family of NICs.
YueHaibing from Huawei fixed the e100 driver that was potentially
passing a NULL pointer, so use the kernel macro IS_ERR_OR_NULL()
instead.
Konstantin Khorenko fixes i40e where we were not setting up the
neigh_priv_len in our net_device, which caused the driver to read beyond
the neighbor entry allocated memory.
Miroslav Lichvar extends the PTP gettime() to read the system clock by
adding support for PTP_SYS_OFFSET_EXTENDED ioctl in i40e.
Young Xiao fixed the ice driver to only enable NAPI on q_vectors that
actually have transmit and receive rings.
Kai-Heng Feng fixes an igb issue that when placed in suspend mode, the
NIC does not wake up when a cable is plugged in. This was due to the
driver not setting PME during runtime suspend.
Stephen Douthit enables the ixgbe driver allow DSA devices to use the
MII interface to talk to switches.

Add a helper to zero fill fields before copying data to
UVERBS_ATTR_STRUCT.
As UVERBS_ATTR_STRUCT can be used as an extensible struct, we want to make
sure that if the user supplies us with a struct that has new fields that
we are not aware of, we return them zeroed to the user.
This helper should be used when using UVERBS_ATTR_STRUCT for an extendable
data structure and there is a need to make sure that extended members of
the struct, that the kernel doesn't handle, are returned zeroed to the
user. This is needed due to the fact that UVERBS_ATTR_STRUCT allows
non-zero values for members after 'last' member.

During testing the command format was changed to close a security
hole. Revise the driver to use the command format that will actually be
supported in GA firmware.
Both the UMEM and UCTX are intended only for use by the kernel and cannot
be executed using a general command.
Since the UMEM and CTX are not part of the general object the caps bits
were moved to be some log_xxx location in the general HCA caps.
The firmware code was adapted as well to match the above.

I210 ethernet card doesn't wakeup when a cable gets plugged. It's
because its PME is not set.
Since commit 42eca2302146 ("PCI: Don't touch card regs after runtime
suspend D3"), if the PCI state is saved, pci_pm_runtime_suspend() stops
calling pci_finish_runtime_suspend(), which enables the PCI PME.
To fix the issue, let's not to save PCI states when it's runtime
suspend, to let the PCI subsystem enables PME.

Section 4.5.9 of the datasheet says that the total size of all packet
buffers combined (TxPB 0 + 1 + 2 + 3 + RxPB + BMC2OS + OS2BMC) must not
exceed 60KB. Today we are configuring a total of 62KB, so reduce the
RxPB from 32KB to 30KB in order to respect that.
The choice of changing RxPBSIZE here is mainly because it seems more
correct to give more priority to the transmit packet buffers over the
receiver ones when running in Qav mode. Also, the BMC2OS and OS2BMC
sizes are already too short.

This change is based off of the work and suggestion of Jan Jablonsky
<jan.jablonsky@thalesgroup.com>.
The Watchdog workqueue in igb driver is scheduled every 2s for each
network interface. That includes updating a statistics protected by
spinlock. Function igb_update_stats in this case will be protected
against preemption. According to number of a statistics registers
(cca 60), processing this function might cause additional cpu load
on CPU0.
In case of statistics spinlock may be replaced with mutex, which
reduce latency on CPU0.

When unregistering fbdev using unregister_framebuffer(), any bound

only framebuffer, resulting in a switch to the dummy console. However if
there is a fb0 and I unregister fb1 having a bound console, I eventually

The problem is in the console rebinding in fbcon_fb_unbind(). It uses the
virtual console index as the new framebuffer index to bind the console(s)
to. The correct way is to use the con2fb_map lookup table to find the
framebuffer index.

Remove dependencies on HAS_DMA where a Kconfig symbol depends on another
symbol that implies HAS_DMA, and, optionally, on "|| COMPILE_TEST".
In most cases this other symbol is an architecture or platform specific
symbol, or PCI.
Generic symbols and drivers without platform dependencies keep their
dependencies on HAS_DMA, to prevent compiling subsystems or drivers that
cannot work anyway.
This simplifies the dependencies, and allows to improve compile-testing.

Blitting an image with "negative" offsets is not working since there
is no clipping. It hopefully just crashes. For the bootup logo, there
is protection so that blitting does not happen as the image is drawn
further and further to the right (ROTATE_UR) or further and further
down (ROTATE_CW). There is however no protection when drawing in the
opposite directions (ROTATE_UD and ROTATE_CCW).
Add back this protection.
The regression is 20-odd years old but the mindless warning-killing
mentality displayed in commit 34bdb666f4b2 ("fbdev: fbmem: remove
positive test on unsigned values") is also to blame, methinks.

In the current kernel, then kzalloc() can't fail for small allocations,
but if it did fail then we would have a NULL dereference in the error
handling. Also in dlfb_usb_disconnect() if "info" were NULL then it
would cause an Oops inside the unregister_framebuffer() function but it
can't be NULL so let's remove that check.

Some dongle doesn't have a valid extended dongle caps,
but we still set the extended dongle caps to be valid.
This causes validation fails for all timing.

don't use extended dongle caps.
