since llvm commit "Do not expand UNDEF SDNode during insn selection lowering"
llvm will generate code that uses uninitialized registers for cases
where C code is actually uses uninitialized data.
So this sockex2 example is technically broken.
Fix it by initializing on the stack variable fully.
Also increase verifier buffer limit, since verifier output
may not fit in 64k for this sockex2 code depending on llvm version.

Goal is to reorganize this critical structure to increase performance.

ndo_start_xmit() should only dirty one cache line, and access as few
cache lines as possible.

Add sp_ (Slow Path) prefix to fields that are not used in fast path,
to make clear what is going on.

After this patch pahole reports something much better, as all
ndo_start_xmit() needed fields are packed into two cache lines instead
of seven or eight

PHY drivers should be able to rely on the caller of {get,set}_tunable to
have acquired the PHY device mutex, in order to both serialize against
concurrent calls of these functions, but also against PHY state machine
changes. All ethtool PHY-level functions do this, except
{get,set}_tunable, so we make them consistent here as well.

We need to update the Microsemi PHY driver in the same commit to avoid
introducing either deadlocks, or lack of proper locking.

Mellanox 100G mlx5 SRIOV switchdev update

This series from Roi and Or further enhances the new SRIOV switchdev mode.

Roi's patches deal with allowing users to configure though devlink
the level of inline headers that the VF should be setting in order for
the eswitch HW to do proper matching. We also enforce that the matching
required for offloaded TC rules is aligned with that level on the PF driver.

Or's patches deals with allowing the user to control on the VF operational
link state through admin directives on the mlx5 VF rep link. Also in this series
is implementation of HW and SW counters for the mlx5 VF rep which is aligned
with the design set by commit a5ea31f5 'Merge branch net-offloaded-stats'.

v1 --> v2:
* constified the net-device param of get offloaded stats ndo in mlxsw
  (pointed by 0-day screaming on us...)
* added Or's Review-by tags for Roi's patches

In commit 2331ccc5 ("tcp: enhance tcp collapsing"),
we made a first step allowing copying right skb to left skb head.

Since all skbs in socket write queue are headless (but possibly the very
first one), this strategy often does not work.

This patch extends tcp_collapse_retrans() to perform frag shifting,
thanks to skb_shift() helper.

This helper needs to not BUG on non headless skbs, as callers are ok
with that.

The VMware VMCI transport supports loopback inside virtual machines.
This patch implements loopback for virtio-vsock.

Flow control is handled by the virtio-vsock protocol as usual.  The
sending process stops transmitting on a connection when the peer's
receive buffer space is exhausted.

Cathy Avery <cavery@redhat.com> noticed this difference between VMCI and
virtio-vsock when a test case using loopback failed.  Although loopback
isn't the main point of AF_VSOCK, it is useful for testing and
virtio-vsock must match VMCI semantics so that userspace programs run
regardless of the underlying transport.

My understanding is that loopback is not supported on the host side with
VMCI.  Follow that by implementing it only in the guest driver, not the
vhost host driver.

All conflicts were simple overlapping changes except perhaps
for the Thunder driver.

That driver has a change_mtu method explicitly for sending
a message to the hardware.  If that fails it returns an
error.

Normally a driver doesn't need an ndo_change_mtu method becuase those
are usually just range changes, which are now handled generically.
But since this extra operation is needed in the Thunder driver, it has
to stay.

However, if the message send fails we have to restore the original
MTU before the change because the entire call chain expects that if
an error is thrown by ndo_change_mtu then the MTU did not change.
Therefore code is added to nicvf_change_mtu to remember the original
MTU, and to restore it upon nicvf_update_hw_max_frs() failue.

Both of these drivers won't work on 64-bit architectures unless they
are redesigned, since they store a virtual address pointer in a 32-bit
field of the descriptors:

drivers/net/ethernet/marvell/mvneta_bm.c: In function 'mvneta_bm_construct':
drivers/net/ethernet/marvell/mvneta_bm.c:103:16: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]
drivers/net/ethernet/marvell/mvpp2.c: In function 'mvpp2_prs_vlan_init':
drivers/net/ethernet/marvell/mvpp2.c:2563:32: error: large integer implicitly truncated to unsigned type [-Werror=overflow]

This limits the COMPILE_TEST option for the two drivers again to
only build them on 32-bit. This seems nicer than shutting up the
warnings, in case we ever actually want to use them on 64-bit,
as the warnings indicate which parts of the driver are currently
broken there.

Start adding support for mv88e6390

This is the first patchset implementing support for the mv88e6390
family.  This is a new generation of switch devices and has numerous
incompatible changes to the registers. These patches allow the switch
to the detected during probe, and makes the statistics unit work.

These patches are insufficient to make the mv88e6390 functional. More
patches will follow.

The mv88e6390 uses a different bit to select between bank0 and bank1

selector bit to the generic stats read function. Also, the histogram
selection has moved for the mv88e6390, so abstract its selection as
well.
