Refactor the TPA logic slightly, so that the code can be more easily
extended to support TPA on the new 57500 chips. In particular, the
logic to get the next aggregation completion is refactored into a
new function bnxt_get_agg() so that this operation is made more
generalized. This operation will be different on the new chip in TPA
mode. The logic to recycle the aggregation buffers has a new start
index parameter added for the same purpose.

Spectrum systems have a configurable limit on how far into the packet they
parse. By default, the limit is 96 bytes.
An IPv6 PTP packet is layered as Ethernet/IPv6/UDP (14+40+8 bytes), and
sequence ID of a PTP event is only available 32 bytes into payload, for a
total of 94 bytes. When an additional 802.1q header is present as
well (such as when ptp4l is running on a VLAN port), the parsing limit is
exceeded. Such packets are not recognized as PTP, and are not timestamped.
Therefore generalize the current VXLAN-specific parsing depth setting to
allow reference-counted requests from other modules as well. Keep it in the
VXLAN module, because the MPRS register also configures UDP destination
port number used for VXLAN, and is thus closely tied to the VXLAN code
anyway.
Then invoke the new interfaces from both VXLAN (in obvious places), as well
as from PTP code, when the (global) timestamping configuration changes from
disabled to enabled or vice versa.

We have an ERPS (Ethernet Ring Protection Switching) setup involving
mv88e6250 switches which we're in the process of switching to a BSP
based on the mainline driver. Breaking any link in the ring works as
expected, with the ring reconfiguring itself quickly and traffic
continuing with almost no noticable drops. However, when plugging back
the cable, we see 5+ second stalls.
This has been tracked down to the userspace application in charge of
the protocol missing a few CCM messages on the good link (the one that
was not unplugged), causing it to broadcast a "signal fail". That
message eventually reaches its link partner, which responds by
blocking the port. Meanwhile, the first node has continued to block
the port with the just plugged-in cable, breaking the network. And the
reason for those missing CCM messages has in turn been tracked down to
the VTU apparently being too busy servicing load/purge operations that
the normal lookups are delayed.
Initial state, the link between C and D is blocked in software.
_____________________
/ \
| |
A ----- B ----- C *---- D
Unplug the cable between C and D.
_____________________
/ \
| |
A ----- B ----- C * * D
Reestablish the link between C and D.
_____________________
/ \
| |
A ----- B ----- C *---- D
Somehow, enough VTU/ATU operations happen inside C that prevents
the application from receving the CCM messages from B in a timely
manner, so a Signal Fail message is sent by C. When B receives
that, it responds by blocking its port.
_____________________
/ \
| |
A ----- B *---* C *---- D
Very shortly after this, the signal fail condition clears on the
BC link (some CCM messages finally make it through), so C
unblocks the port. However, a guard timer inside B prevents it
from removing the blocking before 5 seconds have elapsed.
It is not unlikely that our userspace ERPS implementation could be
smarter and/or is simply buggy. However, this patch fixes the symptoms
we see, and is a small optimization that should not break anything
(knock wood). The idea is simply to avoid doing an VTU load of an
entry identical to the one already present. To do that, we need to
know whether mv88e6xxx_vtu_get() actually found an existing entry, or
has just prepared a struct mv88e6xxx_vtu_entry for us to load. To that
end, let vlan->valid be an output parameter. The other two callers of
mv88e6xxx_vtu_get() are not affected by this patch since they pass
new=false.

There was a previous attempt to use xmit_more, but the change had to be
reverted because under load sometimes a transmit timeout occurred [0].
Maybe this was caused by a missing memory barrier, the new attempt
keeps the memory barrier before the call to netif_stop_queue like it
is used by the driver as of today. The new attempt also changes the
order of some calls as suggested by Eric.

Commit d01f449c008a ("of_net: add NVMEM support to of_get_mac_address")
added support for reading the MAC address from an nvmem-cell. This
required changing the logic to return an error pointer upon failure.
If stmmac is loaded before the nvmem provider driver then
of_get_mac_address() return an error pointer with -EPROBE_DEFER.
Propagate this error so the stmmac driver will be probed again after the
nvmem provider driver is loaded.
Default to a random generated MAC address in case of any other error,
instead of using the error pointer as MAC address.

Hardware supports 0.5K, 1K, 2K, 4K RX buffer size, the

is less the 8192, and dev_alloc_pages has already been used

Align setting PME with the vendor driver. PMEnable is writable on
RTL8169 only, on later chip versions it's read-only. PME_SIGNAL is
used on chip versions from RTL8168evl with the exception of the
RTL8168f family.

ConnectX-3 Pro can offload transmission of VLAN packets with VXLAN inside:
enable tunnel offloads in dev->vlan_features, like it's done with other
NIC drivers (e.g. be2net and ixgbe).
It's no more necessary to change dev->hw_enc_features when VXLAN are added
or removed, since .ndo_features_check() already checks for VXLAN packet
where the UDP destination port matches the configured value. Just set
dev->hw_enc_features when the NIC is initialized, so that overlying VLAN
can correctly inherit the tunnel offload capabilities.
Changes since v1:
- avoid flipping hw_enc_features, instead of calling netdev notifiers,
thanks to Saeed Mahameed
- squash two patches into a single one

The stmmaceth clock is specified by the slave_bus and apb_pclk clocks in
the device tree bindings for snps,dwc-qos-ethernet-4.10 compatible nodes
of this IP.
The subdrivers for these bindings will be requesting the stmmac clock
correctly at a later point, so there is no need to request it here and
cause an error message to be printed to the kernel log.

The Tegra EQOS driver already resets the MDIO bus at probe time via the
reset GPIO specified in the phy-reset-gpios device tree property. There
is no need to reset the bus again later on.
This avoids the need to query the device tree for the snps,reset GPIO,
which is not part of the Tegra EQOS device tree bindings. This quiesces
an error message from the generic bus reset code if it doesn't find the
snps,reset related delays.

Pull Wimplicit-fallthrough enablement from Gustavo A. R. Silva:
"This marks switch cases where we are expecting to fall through, and
globally enables the -Wimplicit-fallthrough option in the main
Makefile.
Finally, some missing-break fixes that have been tagged for -stable:
- drm/amdkfd: Fix missing break in switch statement
- drm/amdgpu/gfx10: Fix missing break in switch statement
With these changes, we completely get rid of all the fall-through
warnings in the kernel"

Mellanox, mlx5 fixes 2019-07-25
This series introduces some fixes to mlx5 driver.
1) Ariel is addressing an issue with enacp flow counter race condition
2) Aya fixes ethtool speed handling
3) Edward fixes modify_cq hw bits alignment
4) Maor fixes RDMA_RX capabilities handling
5) Mark reverses unregister devices order to address an issue with LAG
6) From Tariq,
- wrong max num channels indication regression
- TLS counters naming and documentation as suggested by Jakub
- kTLS, Call WARN_ONCE on netdev mismatch
There is one patch in this series that touches nfp driver to align
TLS statistics names with latest documentation, Jakub is CC'ed.
Please pull and let me know if there is any problem.
For -stable v4.9:
('net/mlx5: Use reversed order when unregister devices')
For -stable v4.20
('net/mlx5e: Prevent encap flow counter update async to user query')
('net/mlx5: Fix modify_cq_in alignment')
For -stable v5.1
('net/mlx5e: Fix matching of speed to PRM link modes')
For -stable v5.2
('net/mlx5: Add missing RDMA_RX capabilities')

The udp_ip4_ind bit is set only for IPv4 UDP non-fragmented packets
so that the hardware can flip the checksum to 0xFFFF if the computed
checksum is 0 per RFC768.
However, this bit had to be set for IPv6 UDP non fragmented packets
as well per hardware requirements. Otherwise, IPv6 UDP packets
with computed checksum as 0 were transmitted by hardware and were
dropped in the network.
In addition to setting this bit for IPv6 UDP, the field is also
appropriately renamed to udp_ind as part of this change.
