We currently need two checks of the peripheral version in MACB_MID register.
One of them got out of sync after modification by 8a013a9c71b2 (net: macb:
Include multi queue support for xilinx ZynqMP ethernet version).
Fix this in macb_configure_caps() so that xilinx ZynqMP will be considered
as a GEM flavor.

User i/o register EMAC_USRIO or GMAC_UR can be found on both macb and gem
flavors of the peripheral. By using the proper accessor, we can add it to the
register dump feature of ethtool.
Increment the version of this API so it can be noticed from user space.

As accessing the peripheral registers need the clocks to be set, we have to
enable them as soon as possible. Their configuration depend on the type of
device used and determined by the DT compatible string. That lead to add
another initialization function in the DT configuration structure.
As the device private structure length depend on an information read in the
registers, we have to store the clock pointers in temporary variables before
feeding the structure fields.

Capabilities configuration by macb_configure_caps() was moved far too late by
421d9df0628b (net/macb: merge at91_ether driver into macb driver) which would
lead to badly configured hardware.
So, move this function to early probe and modify its prototype to re-gain its
original behavior.
DT data retrieval is also moved to simplify the probe code flow.

When merging at91_ether and macb driver during 421d9df0628b (net/macb: merge
at91_ether driver into macb driver) the probe function has been split. The code
dealing with initialization of queues is now moved in macb_init() which needs
information computed in the parent macb_probe() function.
So, add the queue_mask information to the private structure and use it when
needed in macb_init().

The driver uses a bitmask to indicate which statistics should be
displayed to the user in ethtool. The bitmask is u64, therefore we are
limited for a selective view of up to 64 statistics. Extend the bitmap
in order to show more than 64 statistics.
In addition, add packet statistics to the ethtool display for PF.

Return module reference before invoking the respective vport
->destroy() function. This is needed as ovs_vport_del() is not
invoked inside an RCU read side critical section so the kfree
can occur immediately before returning to ovs_vport_del().
Returning the module reference before ->destroy() is safe because
the module unregistration is blocked on ovs_lock which we hold
while destroying the datapath.

We currently have a problem that SELinux policy is being enforced when
creating debugfs files. If a debugfs file is created as a side effect of
doing some syscall, then that creation can fail if the SELinux policy
for that process prevents it.
This seems wrong. We don't do that for files under /proc, for instance,
so Bruce has proposed a patch to fix that.
While discussing that patch however, Greg K.H. stated:
"No kernel code should care / fail if a debugfs function fails, so
please fix up the sunrpc code first."
This patch converts all of the sunrpc debugfs setup code to be void
return functins, and the callers to not look for errors from those
functions.
This should allow rpc_clnt and rpc_xprt creation to work, even if the
kernel fails to create debugfs files for some reason.
Symptoms were failing krb5 mounts on systems using gss-proxy and
selinux.
Fixes: 388f0c776781 "sunrpc: add a debugfs rpc_xprt directory..."

The network protocol used to communicate with the host is the remote ndis (rndis)
protocol. We need to decorate each outgoing packet with a rndis header and
additional rndis state (rndis per-packet state). To manage this state, we
currently allocate memory in the transmit path. Eliminate this allocation by
requesting additional head room in the skb.

This is especially important in cases where the kernel allocs a new
structure and expects a field to be set from a netlink attribute. If such
attribute is shorter than expected, the rest of the field is left containing
previous data. When such field is read back by the user space, kernel memory

Before commit 3900f29021f0bc7fe9815aa32f1a993b7dfdd402 ("bonding: slight
optimizztion for bond_slave_override()") the override logic was to send packets
with non-zero queue_id through the slave with corresponding queue_id, under two
conditions only - if the slave can transmit and it's up.
The above mentioned commit changed this logic by introducing an additional
condition - whether the bond is active (indirectly, using the slave_can_tx and
later - bond_is_active_slave), that prevents the user from implementing more
complex policies according to the Documentation/networking/bonding.txt.

When ipvlan interface with IP addresses attached is brought down and then
deleted, the assigned addresses are deleted twice from the address hash
list, first on the interface down and second on the link deletion.
Similarly, when an address is added while the interface is down, it is added
second time once the interface is brought up.
When the interface is down, the addresses should be kept off the hash list
for performance reasons. Ensure this is true, which also fixes the double add
problem. To fix the double free, check whether the address is hashed before
removing it.
