the ipvlan device driver defines and uses 2 bits inside the priv_flags
net_device field. Such bits and the related helper are used only
inside the ipvlan device driver, and the core networking does not
need to be aware of them.
This change moves netif_is_ipvlan* helper in the ipvlan driver and
re-implement them looking for ipvlan specific symbols instead of
using priv_flags.
Overall this frees two bits inside priv_flags - and move the following
ones to avoid gaps - without any intended functional change.

net: phy: remove phy_error from phy_disable_interrupts
All callers of phy_disable_interrupts() call phy_error() in the error
case. Therefore we don't need to do this within the function too.
This change also allows us to use phy_disable_interrupts() in code
holding phydev->lock (because phy_error() takes this lock).

There are two compatibility strings for mv88e6xxx, but it isn't clear
from the documentation why only those two exist when the mv88e6xxx driver
supports more than the 6085 and 6190. Briefly describe how the compatible
property is used, and provide guidance on which to use.
The model list comes from looking at port_base_addr values (0x0 vs 0x10)
in drivers/net/dsa/mv88e6xxx/chip.c.

The patch adds SLAB_ACCOUNT to flags of net_cachep cache,
which enables accounting of struct net memory to memcg kmem.
Since number of net_namespaces may be significant, user
want to know, how much there were consumed, and control.
Note, that we do not account net_generic to the same memcg,
where net was accounted, moreover, we don't do this at all (*).
We do not want the situation, when single memcg memory deficit
prevents us to register new pernet_operations.
(*)Even despite there is !current process accounting already
available in linux-next. See kmalloc_memcg() there for the details.

This patch adds the support for jumbo frames in the Marvell PPv2 driver.
A third buffer pool is added with 10KB buffers, which is used if the MTU
is higher than 1518B for packets larger than 1518B. Please note only the
port 0 supports hardware checksum offload due to the Tx FIFO size
limitation.

This patch sets the Tx FIFO data size on port 0 to 10kB. This prepares

'HWTSTAMP_TX_ON' should be handled as a value, not as a bit mask.
The modified code should behave the same, because HWTSTAMP_TX_ON is 1

When the driver notices that PCIe link is gone by reading 0xffffffff
from a register it clears hw->hw_addr and then calls netif_device_detach().
This happens when the PCIe device is physically unplugged for example
the user disconnected the Thunderbolt cable.
However, netif_device_detach() prevents netif_unregister() from bringing
the device down properly including tearing down MSI-X vectors. This
triggers following crash during the driver removal:

To prevent the crash do not call netif_device_detach() in igb_rd32().
This should be fine because hw->hw_addr is set to NULL preventing future
hardware access of the now missing device.

These pernet_operations initialize and destroy
net_generic(net, ip_set_net_id)-related data.
Since ip_set is under CONFIG_IP_SET, it's easy
to watch drivers, which depend on this config.
All of them are in net/netfilter/ipset directory,
except of net/netfilter/xt_set.c. There are no
more drivers, which use ip_set, and all of
the above don't register another pernet_operations.
Also, there are is no indirect users, as header
file include/linux/netfilter/ipset/ip_set.h does
not define indirect users by something like this:
#ifdef CONFIG_IP_SET
extern func(void);
#else
static inline func(void);
#endif
So, there are no more pernet operations, dereferencing
net_generic(net, ip_set_net_id).
ip_set_net_ops are OK to be executed in parallel
for several net, so we mark them as async.

The rest of net_generic(net, fou_net_id) accesses

So, these pernet_operations are safe to be marked

These pernet_operations looks similar to dccp_v4_ops,
and they are also safe to be marked as async.

These pernet_operations create and destroy net::dccp::v4_ctl_sk.
It looks like another pernet_operations don't want to send
dccp packets to dying or creating net. Batch method similar
to ipv4/ipv6 sockets and it has to be safe to be executed
in parallel with anything else. So, we mark them as async.
