6dd4859b28 sfc: suppress ENOENT error messages from MC_CMD_MAC_STATS
MC_CMD_MAC_STATS can be called on a function before a
vadaptor has been created, as the kernel can call into this
through ndo_get_stats/ndo_get_stats64.

If MC_CMD_MAC_STATS is called before the DMA queues have been
setup, so that a vadaptor has not been created yet, firmware
will return ENOENT. This is expected, so suppress the MCDI
error message in this case.

0fc95fca5a sfc: update netdevice statistics to use vadaptor stats
The netdevice statistics (in /proc/net/dev) are per-function
stats so they must use the vadaptor stats. Change the use of
MAC stats to vadaptor stats, and remove any statistics that
can only be measured per-port.  All stats that are removed
will be shown as zeroes when these statistics are displayed.

d778819609 sfc: DMA the VF stats only when requested
Firmware does not support a periodic DMA of vadaptor-stats
on VFs, so only update the stats buffer when stats are
requested (when running "ethtool -S" or an ip/ifconfig
command that reports stats).

3c36a2aded sfc: display vadaptor statistics for all interfaces
All interfaces will display vadaptor statistics, so set all the
relevant bits in the stats bitmask. Only functions with the
LINKCTRL flag will see other stats, including (per-port) MAC stats.

The vadaptor stats are from rx_unicast to tx_overflow.

e80ca01399 sfc: add "port_" prefix to MAC stats
The MAC stats are per-port and will only be displayed on the PF
with control of the link (one per physical port). Vadapter stats
will also be displayed for this PF, so distinguish the MAC stats
by adding a prefix of "port_".

161f873b89 vfs: read file_handle only once in handle_to_path
We used to read file_handle twice.  Once to get the amount of extra
bytes, and once to fetch the entire structure.

This may be problematic since we do size verifications only after the
first read, so if the number of extra bytes changes in userspace between
the first and second calls, we'll have an incoherent view of
file_handle.

Instead, read the constant size once, and copy that over to the final
structure without having to re-read it again.

425be5679f x86/asm/irq: Stop relying on magic JMP behavior for early_idt_handlers
The early_idt_handlers asm code generates an array of entry
points spaced nine bytes apart.  It's not really clear from that
code or from the places that reference it what's going on, and
the code only works in the first place because GAS never
generates two-byte JMP instructions when jumping to global
labels.

Clean up the code to generate the correct array stride (member size)
explicitly. This should be considerably more robust against
screw-ups, as GAS will warn if a .fill directive has a negative
count.  Using '. =' to advance would have been even more robust
(it would generate an actual error if it tried to move
backwards), but it would pad with nulls, confusing anyone who
tries to disassemble the code.  The new scheme should be much
clearer to future readers.

While we're at it, improve the comments and rename the array and
common code.

Binutils may start relaxing jumps to non-weak labels.  If so,
this change will fix our build, and we may need to backport this
change.

2d0ec7a19b Revert "iommu/amd: Don't allocate with __GFP_ZERO in alloc_coherent"
This reverts commit 5fc872c732.

The DMA-API does not strictly require that the memory
returned by dma_alloc_coherent is zeroed out. For that
another function (dma_zalloc_coherent) should be used. But
all other x86 DMA-API implementation I checked zero out the
memory, so that some drivers rely on it and break when it is
not.

It seems the (driver-)world is not yet ready for this
change, so revert it.

Scott Feldman says:

====================
rocker: enable by default untagged VLAN support

This patch set is a followup to Simon Horman's RFC patch:

   [PATCH/RFC net-next] rocker: by default accept untagged packets

Now, on port probe, we install untagged VLAN (vid=0) support for each port
as the default.  This is equivalent to the command:

   bridge vlan add vid 0 dev DEV self

Accepting untagged VLAN pkts is a reasonable default, but the user could
override this with:

   bridge vlan del vid 0 dev DEV self

With this, we no longer need 8021q module to install vid=0 when port interface
opens.  In fact, we don't need support for legacy VLAN ndo ops at all since
they're superseded by bridge_setlink/dellink.  So remove legacy VLAN ndo ops
support in driver.  (The legacy VLAN ndo ops are supported by bonding/team
drivers, but don't fit into the transaction model offered by switchdev, so
switching all VLAN functions to bridge_setlink/dellink switchdev support gets
us stacked driver + transaction model support).

2aa2ed0864 rocker: remove support for legacy VLAN ndo ops
Remove support for legacy ndo ops
.ndo_vlan_rx_add_vid/.ndo_vlan_rx_kill_vid.  Rocker will use
bridge_setlink/dellink exclusively for VLAN add/del operations.

The legacy ops are needed if using 8021q driver module to setup VLANs on
the port.  But an alternative exists in using bridge_setlink/delink to
setup VLANs, which doesn't depend on 8021q module.  So rocker will switch
to the newer setlink/dellink ops.  VLANs can added/delete from the port,
regardless if port is bridged or not, using the bridge commands:

	bridge vlan [add|del] vid VID dev DEV self

(Yes, I agree it's confusing to use the "bridge" command to set a VLAN on a
non-bridged port).

Using setlink/dellink over legacy ops let's us handle the stacked driver
case automatically.  It's built-in.  setlink also pass additional flags
(PVID, egress untagged) that aren't available with the legacy ops.

027e00dc0b rocker: install/remove router MAC for untagged VLAN when joining/leaving bridge
When the port joins a bridge, the port's internal VLAN ID needs to change
to the bridge's internal VLAN ID.  Likewise, when leaving the bridge, the
internal VLAN ID reverts back the port's original internal VLAN ID.  (The
internal VLAN ID is used by device to internally mark untagged pkts with
some VLAN, which will eventually be removed on egress...think PVID).  When
the internal VLAN ID changes, we need to update the VLAN table entries and
the router MAC entries for IP/IPv6 to reflect the new internal VLAN ID.

This patch makes use of the common rocker_port_vlan_add/del functions to
make sure the tables are updated for the current internal VLAN ID.

27b808cbc2 rocker: zero allocate ports array
When allocating the array of rocker port pointers, zero the array values so
we can test for !NULL to see if port is allocated/registered.  We'll need
this later when installing untagged VLAN support for each port, during port
probe.  It's a long story, but to install a VLAN (vid=0 for untagged, in
this case) on a port, we'll need to scan other ports to see if the VLAN
group for that VLAN has been setup.  To scan the other ports, we need to
walk the port array.

This patch adds GRO support for non-hardware-accelerated vlan and
improves receive performance of them.
