rcvbuf_policy is set
For sctp assoc, when rcvbuf_policy is set, it will has it's own
rmem_alloc, when we dump asoc info in sctp_diag, we should use that
value on RMEM_ALLOC as well, just like WMEM_ALLOC.

macvtap_device_event(NETDEV_UNREGISTER) should check vlan->minor to
determine if it is being invoked in the context of a macvtap_newlink
that failed, for example in this code sequence:
macvtap_newlink
macvlan_common_newlink
register_netdevice
call_netdevice_notifiers(NETDEV_REGISTER, dev)
macvtap_device_event(NETDEV_REGISTER)
<fail here, vlan->minor = 0>
rollback_registered(dev);
rollback_registered_many
call_netdevice_notifiers(NETDEV_UNREGISTER, dev);
macvtap_device_event(NETDEV_UNREGISTER)
<nothing to clean up here>

If macvlan_common_newlink fails in register_netdevice after macvlan_init
then it decrements port->count twice, first in macvlan_uninit (from
register_netdevice or rollback_registered) and then again in
macvlan_common_newlink.
A similar problem may exist in the ipvlan driver.
This patch consolidates modifications to port->count into macvlan_init
and macvlan_uninit (thanks to Eric Biederman for suggesting this approach).
v3: remove macvtap specific bits.

The firmware can send a set of asynchronous replies through FW_PORT_CMD
with DCBX information when that's negotiated with the Link Peer. The old
code always assumed that a FW_PORT_CMD reply was always a Get Port
Information message. This change conditionalizes the code to only handle
the Get Port Information messages and throws a warning if we don't
understand what we've been given.
Also refactor t4_handle_fw_rpl() so that core functionality performed by
t4_handle_get_port_info() for a specified port.

There could be race between t4_eth_xmit() and t4_free_sge_resources() while

If the PF driver reports proper support, allow the PF driver to
configure RSS on the behalf of the VF driver. This will allow for RSS
support on future hardware without changes to the VF driver.
Unfortunately, the old RSS code still needs to stay as the driver needs
to be compatible with PF drivers that don't support this interface. But
this change still simplifies the data structures a bunch and makes this
code simpler to read and maintain.

====================
netlink: align attributes when needed (patchset #3)
This is the continuation (series #3) of the work done to align netlink
attributes when these attributes contain some 64-bit fields.
It's the last patchset from what I've seen.
The last user of nla_put_u64() is block/drbd. This module does not use
standard netlink API (see all the stuff in include/linux/genl_magic_struct.h
and include/linux/genl_magic_func.h). I didn't modify it because it's seems
hard to do it whithout testing and fully understanding the context (for
example, why include/linux/drbd_genl.h is not part of uapi?).
Any thoughts?

It was a simple idea -- save IPv6 configured addresses on a link down
so that IPv6 behaves similar to IPv4. As always the devil is in the
details and the IPv6 stack as too many behavioral differences from IPv4
making the simple idea more complicated than it needs to be.
The current implementation for keeping IPv6 addresses can panic or spit
out a warning in one of many paths:
1. IPv6 route gets an IPv4 route as its 'next' which causes a panic in
rt6_fill_node while handling a route dump request.
2. rt->dst.obsolete is set to DST_OBSOLETE_DEAD hitting the WARN_ON in
fib6_del
3. Panic in fib6_purge_rt because rt6i_ref count is not 1.
The root cause of all these is references related to the host route for
an address that is retained.
So, this patch deletes the host route every time the ifdown loop runs.
Since the host route is deleted and will be re-generated an up there is
no longer a need for the l3mdev fix up. On the 'admin up' side move
addrconf_permanent_addr into the NETDEV_UP event handling so that it
runs only once versus on UP and CHANGE events.
All of the current panics and warnings appear to be related to
addresses on the loopback device, but given the catastrophic nature when
a bug is triggered this patch takes the conservative approach and evicts
all host routes rather than trying to determine when it can be re-used
and when it can not. That can be a later optimizaton if desired.

Currently ARM CPUs DT bindings allows different enable-method value for
PSCI based systems. On ARM 64-bit this property is required and must be
"psci" while on ARM 32-bit systems this property is optional and must
be "arm,psci" if present.
However, "arm,psci" has always been the compatible string for the PSCI
node, and was never intended to be the enable-method. So this is a bug
in the binding and not a deliberate attempt at specifying 32-bit
differently.
This is problematic if 32-bit OS is run on 64-bit system which has
"psci" as enable-method rather than the expected "arm,psci".
So let's unify the value into "psci" and remove support for "arm,psci"
before it finds any users.

Under some circumstances the driver remove function may be called before
the driver is fully initialized. So we can't assume that we know where
our towel is at, or that all of the data structures are initialized.
To ensure that we don't panic, check that the vsi_res pointer is valid
before dereferencing it. Then drink beer and eat peanuts.

The feature flags list for i40e and i40evf is beginning to become pretty
massive. I plan to add another 4 or so features to these drivers and
duplicating the flags for each and every flags list is becoming a bit
repetitive.
The primary change here is that we now build our features list around
hw_encap_features. After that we assign that to vlan_features,
hw_features, and finally map that onto features. In addition we end up
throwing features onto hw_encap_features that end up having no effect such
as the Rx offloads and SCTP_CRC. However that should have no impact and
makes things a bit easier for us as hw_encap_features is one of the less
updated features maps available.
For i40evf I went through and sanity checked a few features as well.
Specifically RXCSUM was being set as a read-only feature which didn't make
much sense. I have updated things so we can clear the NETIF_F_RXCSUM flag
since that is really a software feature and not a hardware one anyway so
disabling it is just a matter of ignoring the result from the hardware.

In commit 97f95c93c8ed ("iwlwifi: remove support for fw older than

DVM devices. The code intended to remove the old fw version API,
because all MVM firmwares version 16 and above that we support don't
use it anymore. But DVM devices still use the old FW API.
Fix that by bringing the code back in.
