Pull networking fixes from David Miller:
1) Fix handling of initial STATE message in TIPC, from Jon Paul Maloy.
2) Fix stats handling in bcm_sysport_get_stats(), from Florian
Fainelli.
3) Reject 16777215 VNI value in geneve_validate(), from Girish
Moodalbail.
4) Fix initial IGMP sysctl setting regression, from Nikolay Borisov.
5) Once a UFO fragmented frame is treated as UFO, we should continue
doing so. Likewise once a frame has been segmented, we should
continue doing that and not try to convert it to a UFO frame. From
Willem de Bruijn.
6) Test the AF_PACKET RX/TX ring pg_vec state under the socket lock to
prevent races. From Willem de Bruijn.

This patch is in preparation for adding HW flow and QoS offloading. For
those features to work, the driver needs to bring up the first QDMA RX
ring. This ring is used by the PPE offloading HW.

Geneve's Virtual Network Identifier (VNI) is 24 bit long, so the range
of values for it would be from 0 to 16777215 (2^24 -1). However, one
cannot create a geneve device with VNI set to 16777215. This patch fixes
this issue.

With SYSTEMPORT Lite we have holes in our statistics layout that make us
skip over the hardware MIB counters, bcm_sysport_get_stats() was not
taking that into account resulting in reporting 0 for all SW-maintained

Using mpgroup to define multiple paths for a virtual disk causes multiple
virtual-device-port ports to be created for that virtual device.
Each virtual-device-port port then gets a vdisk created for it by the Linux
sunvdc driver. As mpgroup is not supported by the Linux sunvdc driver it
cannot handle multiple ports for a single vdisk, leading to a kernel panic
at startup.
This fix prevents more than one vdisk per virtual-device-port being created
until full virtual disk multipathing (mpgroup) support is implemented.

Jeff Kirsher says:
====================
1GbE Intel Wired LAN Driver Updates 2017-08-08
This series contains updates to e1000e and igb/igbvf.
Gangfeng Huang fixes an issue with receive network flow classification,
where igb_nfc_filter_exit() was not being called in igb_down() which
would cause the filter tables to "fill up" if a user where to change
the adapter settings (such as speed) which requires a reset of the
adapter.
Cliff Spradlin fixes a timestamping issue, where igb was allowing requests
for hardware timestamping even if it was not configured for hardware
transmit timestamping.
Corinna Vinschen removes the error message that there was an "unexpected
SYS WRAP", when it is actually expected. So remove the message to not
confuse users.
Greg Edwards provides several patches for the mailbox interface between
the PF and VF drivers. Added a mailbox unlock method to be used to unlock
the PF/VF mailbox by the PF. Added a lock around the VF mailbox ops to
prevent the VF from sending another message while the PF is still
processing the previous message. Fixed a "scheduling while atomic" issue
by changing msleep() to mdelay().
Sasha adds support for the next LOM generations i219 (v8 & v9) which
will be available in the next Intel client platform IceLake.
John Linville adds support for a Broadcom PHY to the igb driver, since
there are designs out in the world which use the igb MAC and a third
party PHY. This allows the driver to load and function as expected on
these designs.

The UDP offload conflict is dealt with by simply taking what is
in net-next where we have removed all of the UFO handling code
entirely.
The TCP conflict was a case of local variables in a function
being removed from both net and net-next.
In netvsc we had an assignment right next to where a missing
set of u64 stats sync object inits were added.

Commit e5dadc65f9e0 ("ppp: Fix false xmit recursion detect with two ppp
devices") dropped the xmit_recursion counter incrementation in
ppp_channel_push() and relied on ppp_xmit_process() for this task.
But __ppp_channel_push() can also send packets directly (using the
.start_xmit() channel callback), in which case the xmit_recursion
counter isn't incremented anymore. If such packets get routed back to
the parent ppp unit, ppp_xmit_process() won't notice the recursion and
will call ppp_channel_push() on the same channel, effectively creating
the deadlock situation that the xmit_recursion mechanism was supposed
to prevent.
This patch re-introduces the xmit_recursion counter incrementation in
ppp_channel_push(). Since the xmit_recursion variable is now part of
the parent ppp unit, incrementation is skipped if the channel doesn't
have any. This is fine because only packets routed through the parent
unit may enter the channel recursively.
Finally, we have to ensure that pch->ppp is not going to be modified
while executing ppp_channel_push(). Instead of taking this lock only
while calling ppp_xmit_process(), we now have to hold it for the full
ppp_channel_push() execution. This respects the ppp locks ordering
which requires locking ->upl before ->downl.

No need for calling the NOTIFY_PEERS notifier since that is only for

Two of the VF mailbox commands were not waiting for a reply from the PF,
which can result in a VF mailbox timeout in the VM for the next command.

Manually adjust the port settings of user ports once PHY polling has
completed. This patch extends the adjust_link callback to configure the
per port PMCR register, applying the proper values polled from the PHY.
Without this patch flow control was not always getting setup properly.

if the NIC fails to validate the checksum on TCP/UDP, and validation of IP
checksum is successful, the driver subtracts the pseudo-header checksum
from the value obtained by the hardware and sets CHECKSUM_COMPLETE. Don't
do that if protocol is IPPROTO_SCTP, otherwise CRC32c validation fails.

The PF driver assumes the VF will not send another mailbox message until
the PF has written its reply to the previous message. If the VF does,
that message will be silently dropped by the PF before it writes its
reply to the mailbox. This results in a VF mailbox timeout for posted
messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Add a lock around the VF mailbox ops to prevent the VF from sending
another message while the PF is still processing the previous one.

When the PF receives a mailbox message from the VF, it grabs the mailbox
lock, reads the VF message from the mailbox, ACKs the message and drops
the lock.
While the PF is performing the action for the VF message, nothing
prevents another VF message from being posted to the mailbox. The
current code handles this condition by just dropping any new VF messages
without processing them. This results in a mailbox timeout in the VM
for posted messages waiting for an ACK, and the VF is reset by the
igbvf_watchdog_task in the VM.
Given the right sequence of VF messages and mailbox timeouts, this
condition can go on ad infinitum.
Modify the PF mailbox read method to take an 'unlock' argument that
optionally leaves the mailbox locked by the PF after reading the VF
message. This ensures another VF message is not posted to the mailbox
until after the PF has completed processing the VF message and written
its reply.

Unifies adjusted and unadjusted register value types (e.g. FRAME_POINTER is
now just a PTR_TO_STACK with zero offset).
Tracks value alignment by means of tracking known & unknown bits. This
also replaces the 'reg->imm' (leading zero bits) calculations for (what
were) UNKNOWN_VALUEs.
If pointer leaks are allowed, and adjust_ptr_min_max_vals returns -EACCES,
treat the pointer as an unknown scalar and try again, because we might be
able to conclude something about the result (e.g. pointer & 0x40 is either
0 or 0x40).
Verifier hooks in the netronome/nfp driver were changed to match the new
data structures.
