All Marvell switches supported by mv88e6xxx have to set their device
number in the Global Control 2 register. Extract this in a read then
write function, called from the device mapping setup code.

Only the 88E6185 family has bits 15:12 Cascade Port bits in the Global
Control 2 register. Hence inconsistent values are actually written in
this register for other families.

Add a .set_cascade_port operation to isolate the 88E6185 case, and call
it from the device mapping setup function.

mlx4_core misc for 4.18

This patchset contains misc enhancements from the team
to the mlx4 Core driver.

Patch 1 by Eran adds driver version report in FW.
Patch 2 by Yishai implements suspend/resume PCI callbacks.
Patch 3 extends the range of an existing module param from boolean to numerical.

Extend the boolean interpretation of msi_x module parameter
to numerical, as follows:

0   - Don't use MSI-X.
1   - Use MSI-X, driver decides the num of MSI-X irqs.
>=2 - Use MSI-X, limit number of MSI-X irqs to msi_x.
      In SRIOV, this limits the number of MSI-X irqs per VF.

Commit 161d82de ("net: bridge: Notify about !added_by_user FDB
entries") causes the below oops when bringing up a slave interface,
because dsa_port_fdb_add is still scheduled, but with a NULL address.

To fix this, keep the dsa_slave_switchdev_event function agnostic of the
notified info structure and handle the added_by_user flag in the
specific dsa_slave_switchdev_event_work function.

In commit be47e41d ("tipc: fix use-after-free in tipc_nametbl_stop")
we fixed a problem caused by premature release of service range items.

That fix is correct, and solved the problem. However, it doesn't address
the root of the problem, which is that we don't lookup the tipc_service
 -> service_range -> publication items in the correct hierarchical
order.

In this commit we try to make this right, and as a side effect obtain

This adds support for U32 filter by using an HW only feature called
Flexible RX Parser. This allow us to match any given packet field with a
pattern and accept/reject or even route the packet to a specific DMA
channel.

Right now we only support acception or rejection of frame and we only
support simple rules. Though, the Parser has the flexibility of jumping to
specific rules as an if condition so complex rules can be established.

This is only supported in GMAC5.10+.

The following commands can be used to test this code:

	1) Setup an ingress qdisk:
	# tc qdisc add dev eth0 handle ffff: ingress

	2) Setup a filter (e.g. filter by IP):
	# tc filter add dev eth0 parent ffff: protocol ip u32 match ip \
		src 192.168.0.3 skip_sw action drop

In every tests performed we always used the "skip_sw" flag to make sure
only the RX Parser was involved.

UDP GSO Segmentation clean-ups

This patch set addresses a number of issues I found while sorting out
enabling UDP GSO Segmentation support for ixgbe/ixgbevf. Specifically there
were a number of issues related to the checksum and such that seemed to
cause either minor irregularities or kernel panics in the case of the
offload request being allowed to traverse between name spaces.

With this set applied I am was able to get UDP GSO traffic to pass over
vxlan tunnels in both offloaded modes and non-offloaded modes for ixgbe and
ixgbevf.

I submitted the driver specific patches earlier as an RFC:

This patch makes it so that if a destructor is not present we avoid trying
to update the skb socket or any reference counting that would be associated
with the NULL socket and/or descriptor. By doing this we can support
traffic coming from another namespace without any issues.

This patch adds support for a software provided checksum and GSO_PARTIAL
segmentation support. With this we can offload UDP segmentation on devices
that only have partial support for tunnels.

Since we are no longer needing the hardware checksum we can drop the checks
in the segmentation code that were verifying if it was present.

This patch allows us to take care of unrolling the first segment and the
last segment of the loop for processing the segmented skb. Part of the
motivation for this is that it makes it easier to process the fact that the
first fame and all of the frames in between should be mostly identical
in terms of header data, and the last frame has differences in the length
and partial checksum.

In addition I am dropping the header length calculation since we don't
really need it for anything but the last frame and it can be easily
obtained by just pulling the data_len and offset of tail from the transport
header.

This patch is meant to allow us to avoid having to recompute the checksum
from scratch and have it passed as a parameter.

Instead of taking that approach we can take advantage of the fact that the
length that was used to compute the existing checksum is included in the
UDP header.

Finally to avoid the need to invert the result we can just call csum16_add
and csum16_sub directly. By doing this we can avoid a number of
instructions in the loop that is handling segmentation.

There is no point in passing MSS as a parameter for for the GSO
segmentation call as it is already available via the shared info for the
skb itself.

We need to record the number of segments that will be generated when this
frame is segmented. The expectation is that if gso_size is set then
gso_segs is set as well. Without this some drivers such as ixgbe get
confused if they attempt to offload this as they record 0 segments for the
entire packet instead of the correct value.

When computing the bitrate using values read from an SFP module EEPROM,
we use the nominal BR plus BR,min and BR,max to determine the
boundaries. But in some cases BR,min and BR,max aren't provided, which
led the SFP code to end up having the nominal value for both the minimum
and maximum bitrate values. When using a passive cable, the nominal
value should be used as the maximum one, and there is no minimum one
so we should use 0.

bnxt_en: Fixes for net-next.

This series includes a bug fix for a regression in firmware message polling
introduced recently on net-next.  There are 3 additional minor fixes for
unsupported link speed checking, VF MAC address handling, and setting
PHY eeprom length.

The current code already forwards the VF MAC address to the PF, except
in one case.  If the VF driver gets a valid MAC address from the firmware
during probe time, it will not forward the MAC address to the PF,
incorrectly assuming that the PF already knows the MAC address.  This
causes "ip link show" to show zero VF MAC addresses for this case.

This assumption is not correct.  Newer firmware remembers the VF MAC
address last used by the VF and provides it to the VF driver during
probe.  So we need to always forward the VF MAC address to the PF.

The forwarded MAC address may now be the PF assigned MAC address and so we
need to make sure we approve it for this case.

For SFP+ modules, 0xA2 page is available only when Diagnostic Monitoring
Type [Address A0h, Byte 92] is implemented. Extend bnxt_get_module_info(),
to read optical diagnostics support at offset 92(0x5c) and set eeprom_len
length to ETH_MODULE_SFF_8436_LEN (to exclude A2 page), if dianostics is
not supported.

Also in bnxt_get_module_info(), module id is read from offset 0x5e which
is not correct. It was working by accident, as offset was not effective
without setting enables flag in the firmware request. SFP module id is
present at location 0. Fix this by removing the offset and read it
from location 0.

Only non-NPAR PFs need to actively check and manage unsupported link
speeds.  NPAR functions and VFs do not control the link speed and
should skip the unsupported speed detection logic, to avoid warning
messages from firmware rejecting the unsupported firmware calls.

A recent change to reduce delay granularity waiting for firmware
reponse has caused a regression.  With a tighter delay loop,
the driver may see the beginning part of the response faster.
The original 5 usec delay to wait for the rest of the message
is not long enough and some messages are detected as invalid.

Increase the maximum wait time from 5 usec to 20 usec.  Also, fix
the debug message that shows the total delay time for the response
when the message times out.  With the new logic, the delay time
is not fixed per iteration of the loop, so we define a macro to
show the total delay time.

When the core networking needs to detect the transport offset in a given
packet and parse it explicitly, a full-blown flow_keys struct is used for
storage.
This patch introduces a smaller keys store, rework the basic flow dissect
helper to use it, and apply this new helper where possible - namely in
skb_probe_transport_header(). The used flow dissector data structures
are renamed to match more closely the new role.

The above gives ~50% performance improvement in micro benchmarking around
skb_probe_transport_header() and ~30% around eth_get_headlen(), mostly due
to the smaller memset. Small, but measurable improvement is measured also
in macro benchmarking.

v1 -> v2: use the new helper in eth_get_headlen() and skb_get_poff(),
  as per DaveM suggestion

net/ipv6 misc

This patchset contains two patches for net/ipv6.

Patch 1 is a trivial typo fix in documentation.
Patch 2 by Eran is a re-spin. It adds GRO support for IPv6 GRE tunnel,
this significantly improves performance in case GRO in native interface
is disabled.
