Different hashes have the same class key because they get
initialised with the same one. For this reason lockdep can create

The current timeout is set to one hour. However a client connected to the mesh
network will always generate traffic. In the worst case it will send ARP
requests every 4 or 5 minutes. On the other hand having a long timeout means
storing dead entries for one hour and it leads to very big trans-tables
containing useless clients.
This patch reduces the timeout to 10 minutes

net: provide a default dev->ethtool_ops
wireless core does not correctly assign ethtool_ops.
After alloc_netdev*() call, some cfg80211 drivers provide they own
ethtool_ops, but some do not. For them, wireless core provide generic
cfg80211_ethtool_ops, which is assigned in NETDEV_REGISTER notify call:
if (!dev->ethtool_ops)
dev->ethtool_ops = &cfg80211_ethtool_ops;
But after Eric's commit, dev->ethtool_ops is no longer NULL (on cfg80211
drivers without custom ethtool_ops), but points to &default_ethtool_ops.
In order to fix the problem, provide function which will overwrite
default_ethtool_ops and use it by wireless core.

This change is meant to address several issues I found within the
netif_set_xps_queues function.
If the allocation of one of the maps to be assigned to new_dev_maps failed
we could end up with the device map in an inconsistent state since we had
already worked through a number of CPUs and removed or added the queue. To
address that I split the process into several steps. The first of which is
just the allocation of updated maps for CPUs that will need larger maps to
store the queue. By doing this we can fail gracefully without actually
altering the contents of the current device map.
The second issue I found was the fact that we were always allocating a new
device map even if we were not adding any queues. I have updated the code
so that we only allocate a new device map if we are adding queues,
otherwise if we are not adding any queues to CPUs we just skip to the
removal process.
The last change I made was to reuse the code from remove_xps_queue to remove
the queue from the CPU. By making this change we can be consistent in how
we go about adding and removing the queues from the CPUs.

This patch does a minor refactor on netif_reset_xps_queue to address a few
items I noticed.
First is the fact that we are doing removal of queues in both
netif_reset_xps_queue and netif_set_xps_queue. Since there is no need to
have the code in two places I am pushing it out into a separate function
and will come back in another patch and reuse the code in
netif_set_xps_queue.
The second item this change addresses is the fact that the Tx queues were
not getting their numa_node value cleared as a part of the XPS queue reset.
This patch resolves that by resetting the numa_node value if the dev_maps
value is set.
