netlink: strict attribute checking follow-up

Three follow-up patches for recent strict netlink validation series.

Patch 1 fixes dump handling for genetlink families which validate and parse
messages themselves (e.g. because they need different policies for diferent
commands).

Patch 2 sets bad_attr in extack in one place where this was omitted.

Patch 3 adds new NL_VALIDATE_NESTED flags for strict validation to enable
checking that NLA_F_NESTED value in received messages matches expectations
and includes this flag in NL_VALIDATE_STRICT. This would change userspace
visible behavior but the previous switching to NL_VALIDATE_STRICT for new
code is still only in net-next at the moment.

Unlike do requests, dump genetlink requests now perform strict validation
by default even if the genetlink family does not set policy and maxtype
because it does validation and parsing on its own (e.g. because it wants to
allow different message format for different commands). While the null
policy will be ignored, maxtype (which would be zero) is still checked so
that any attribute will fail validation.

The solution is to only call __nla_validate() from genl_family_rcv_msg()
if family->maxtype is set.

mlxsw: Firmware version update

This patchset updates mlxsw to use a new firmware version and adds
support for split into two ports on Spectrum-2 based systems.

Patch #1 updates the firmware version to 13.2000.1122

Patch #2 queries new resources from the firmware.

Patch #3 makes use of these resources in order to support split into two
ports on Spectrum-2 based systems. The need for these resources is
explained by Shalom:

When splitting a port, different local ports need to be mapped on different
systems. For example:

SN3700 (local_ports_in_2x=2):
  * Without split:
      front panel 1   --> local port 1
      front panel 2   --> local port 5
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 3
      front panel 2   --> local port 5

SN3800 (local_ports_in_2x=1):
  * Without split:
      front panel 1 --> local port 1
      front panel 2 --> local port 3
  * Split to 2:
      front panel 1s0 --> local port 1
      front panel 1s1 --> local port 2
      front panel 2   --> local port 3

The local_ports_in_{1x, 2x} resources provide the offsets from the base
local ports according to which the new local ports can be calculated.

TIPC link can temporarily fall into "half-establish" that only one of
the link endpoints is ESTABLISHED and starts to send traffic, PROTOCOL
messages, whereas the other link endpoint is not up (e.g. immediately
when the endpoint receives ACTIVATE_MSG, the network interface goes
down...).

This is a normal situation and will be settled because the link
endpoint will be eventually brought down after the link tolerance time.

However, the situation will become worse when the second link is
established before the first link endpoint goes down,
For example:

   1. Both links <1A-2A>, <1B-2B> down
   2. Link endpoint 2A up, but 1A still down (e.g. due to network
      disturbance, wrong session, etc.)
   3. Link <1B-2B> up
   4. Link endpoint 2A down (e.g. due to link tolerance timeout)
   5. Node B starts failover onto link <1B-2B>

   ==> Node A does never start link failover.

When the "half-failover" situation happens, two consequences have been
observed:

a) Peer link/node gets stuck in FAILINGOVER state;
b) Traffic or user messages that peer node is trying to failover onto
the second link can be partially or completely dropped by this node.

The consequence a) was actually solved by commit c140eb16 ("tipc:
fix failover problem"), but that commit didn't cover the b). It's due
to the fact that the tunnel link endpoint has never been prepared for a
failover, so the 'l->drop_point' (and the other data...) is not set
correctly. When a TUNNEL_MSG from peer node arrives on the link,
depending on the inner message's seqno and the current 'l->drop_point'
value, the message can be dropped (- treated as a duplicate message) or
processed.
At this early stage, the traffic messages from peer are likely to be
NAME_DISTRIBUTORs, this means some name table entries will be missed on
the node forever!

The commit resolves the issue by starting the FAILOVER process on this
node as well. Another benefit from this solution is that we ensure the
link will not be re-established until the failover ends.

I got an interesting report [0] that after resuming from hibernation
the link has 100Mbps instead of 1Gbps. Reason is that another OS has
been used whilst Linux was hibernated. And this OS speeds down the link
due to WoL. Therefore, when resuming, we shouldn't expect that what
the PHY advertises is what it did when hibernating.
Easiest way to do this is removing state PHY_RESUMING. Instead always
go via PHY_UP that configures PHY advertisement.

When probing the phy device we set sym and asym pause in the "supported"
bitmap (unless the PHY tells us otherwise). However we don't know yet
whether the MAC supports pause. Simply copying phy->supported to
phy->advertising will trigger advertising pause, and that's not
what we want. Therefore add phy_advertise_supported() that copies all
modes but doesn't touch the pause bits.

In phy_support_(a)sym_pause we shouldn't set any bits in the supported
bitmap because we may set a bit the PHY intentionally disabled.
Effective pause support should be the AND-combined PHY and MAC pause
capabilities. If the MAC supports everything, then it's only relevant
what the PHY supports. If MAC supports sym pause only, then we have to
clear the asym bit in phydev->supported.
Copy the pause flags only and don't touch the modes, because a driver
may have intentionally removed a mode from phydev->advertising.

100GbE Intel Wired LAN Driver Updates 2019-05-02

This series contains updates to the ice driver only.

Anirudh introduces the framework to store queue specific information in
the VSI queue contexts.  This will allow future changes to update the
structure to hold queue specific information.

Akeem adds additional check so that if there is no queue to disable when
attempting to disable a queue, return a configuration error without
acquiring the lock.  Fixed an issue with non-trusted VFs being able to
add more than the permitted number of VLANs.

Bruce removes unreachable code and updated the function to return void
since it would never return anything but success.

Brett provides most of the changes in the series, starting with reducing
the scope of the error variable used and improved the debug message if
we fail to configure the receive queue.  Updates the driver to use a
macro instead of using the same 'for' loop throughout the driver which
helps with readability.  Fixed an issue where users were led to believe
they could set rx-usecs-high value, yet the changes to this value would
not stick because it was not yet implemented to allow changes to this
value, so implement the missing code to change the value.  Found we had
unnecessary wait when disabling queues, so remove it.  I,proved a
wasteful addition operation in our hot path by adding a member to the
ice_q_vector structure and the necessary changes to use the member which
stores the calculated vector hardware index.  Refactored the link event
flow to make it cleaner and more clear.

Maciej updates the array index when stopping transmit rings, so that
process every ring the VSI, not just the rings in a given transmit
class.

Paul adds support for setting 52 byte RSS hash keys.

Md Fahad cleaned up a runtime change to the PFINT_OICR_ENA register,
since the interrupt handlers will handle resetting the bit, if
necessary.

Tony adds a missing PHY type, which was causing warning message about an

approach, it is required for the driver to have support for
"transition firmware", that is used for migrating from structured
to flat firmware image. In this new, very basic mode, i40e driver
must be able to handle particular IOCTL calls from the NVM Update
Tool and run a small set of AQ commands.

These additional AQ commands are part of the interface used by
the NVMUpdate tool.  The NVMUpdate tool contains all of the
necessary logic to reference these new AQ commands.  The end user
experience remains the same, they are using the NVMUpdate tool to
update the NVM contents.

The function i40e_validate_cloud_filter checks that the destination and
source port numbers are valid by attempting to ensure that the number is
non-zero and no larger than 0xFFFF. However, the types for the dst_port
and src_port variable are __be16 which by definition cannot be larger
than 0xFFFF

Since these values cannot be larger than 2 bytes, the check to see if
they exceed 0xFFFF is meaningless.

One might consider these checks as some sort of defensive coding, in
case the type was later changed. However, these checks also byte-swap
the value before comparison using be16_to_cpu, which will truncate the
values to 16bits anyways. Additionally, changing the type would require
updating the opcodes to support new data layout of these virtchnl
commands.
