These pernet_operations allocate and destroy IDA identifier,
and these actions are synchronized by IDA subsystem locks.
Exit method removes mac80211_hwsim_data enteries from the lists,
and this is synchronized by hwsim_radio_lock with the rest
parallel pernet_operations. Also it queues destroy_radio()
work, and these work already may be executed in parallel
with any pernet_operations (as it's a work :). So, we may
mark these pernet_operations as async.

hwsim_netgroup counter is declarated as int, and it is incremented
every time a new net is created. After sizeof(int) net are created,
it will overflow, and different net namespaces will have the same
identifier. This patch fixes the problem by introducing IDA instead
of int counter. IDA guarantees, all the net namespaces have the uniq
identifier.
Note, that after we do ida_simple_remove() in hwsim_exit_net(),
and we destroy the ID, later there may be executed destroy_radio()
from the workqueue. But destroy_radio() does not use the ID, so it's OK.
Out of bounds of this patch, just as a report to wireless subsystem
maintainer, destroy_radio() increaments hwsim_radios_generation
without hwsim_radio_lock, so this may need one more patch to fix.

'default false' should be 'default n', though they happen to have the
same effect here, due to undefined symbols ('false' in this case)
evaluating to n in a tristate sense.
Remove the default instead of changing it. bool and tristate symbols

In the scheduler config command, the meaning of tid == 0xf was intended
to indicate the configuration is for management frames. However,
tid == 0xf was also used for the multicast queue that was meant only
for multicast data frames, which resulted with the FW not encrypting
multicast data frames.
As multicast frames do not have a QoS header, fix this by setting
tid == 0, to indicate that this is a data queue and not management
one.

When the GTK is installed, we install it to HW with the
station ID of the AP.
Mac80211 will try to remove it only after the AP sta is
removed, which will result in a failure to remove key
since we do not have any station for it.
This is a valid situation, but a previous commit removed
the early return and added a return with error value, which
resulted in an error message that is confusing to users.
Remove the error return value.

Trying to collect firmware debug data while firmware
is not loaded causes various errors (e.g. failing NIC access).
This causes even a bigger issue if at that time the
HW radio is off.
In that case, when later turning the radio on, the Driver
fails to read the HW (registers contain garbage values).
(It may be that the CSR_GP_CNTRL_REG_FLAG_RFKILL_WAKE_L1A_EN
bit is cleared on faulty NIC access - since the same behavior
was seen in HW RFKILL toggling before setting that bit.)

We should add the multicast station before adding the
broadcast station.
However, in older FW, the firmware will start beaconing
when we add the multicast station, and since the broadcast
station is not added at this point so the transmission
of the beacon will fail on assert 0x2b00.
This is fixed in later firmware, so make the order
of addition depend on the TLV.

While entering to D3 mode there is a gap between the time the
driver handles the D3_CONFIG_CMD response to the time the host is going
to sleep.
In between there might be cases which MARKER_CMD can tailgate.
Also during resume flow the MARKER_CMD might get sent while D0I3_CMD
is being handled in the FW.
Cancel MARKER_CMD timer and set it again properly during suspend
resume flows to prevent this command from being sent accidentlly.

As a part of working on MII time stamping infrastructure, I was trying
to figure out how netdev->phydev gets assigned, and I stumbled across
this. Ever since the new phylink code came in, the field is assigned
twice.
The function, phylink_connect_phy(), calls
phy_attach_direct()
phylink_bringup_phy()
and phy_attach_direct() sets
dev->phydev = phydev;
but phylink_bringup_phy() then sets the same field again:
pl->netdev->phydev = phy;
Similarly, the function, phylink_of_phy_connect(), calls
of_phy_attach()
phy_attach_direct()
phylink_bringup_phy()
The removal code is also duplicated:
phylink_disconnect_phy()
pl->netdev->phydev = NULL;
phy_disconnect()
phy_detach()
phydev->attached_dev->phydev = NULL;
This patch removes the redundant assignments, restricting manipulation
of the netdev.phydev field to phy_attach_direct() and phy_detach().

mfc_cache and mfc6_cache are almost identical - the main difference is
in the origin/group addresses and comparison-key. Make a common
structure encapsulating most of the multicast routing logic - mr_mfc
and convert both ipmr and ip6mr into using it.
For easy conversion [casting, in this case] mr_mfc has to be the first

A toolstack may delete the vif frontend and backend xenstore entries
while xen-netfront is in the removal code path. In that case, the
checks for xenbus_read_driver_state would return XenbusStateUnknown, and

One of the basic construct in the device is a port-VLAN pair, which can
be bound to a FID or a RIF in order to direct packets to the bridge or
the router, respectively.
Since not all the netdevs are configured with a VLAN (e.g., sw1p1 vs.
sw1p1.10), VID 1 is used to represent these and thus this VID can be
used by both upper devices of mlxsw ports and by the driver itself.
However, this VID is not reference counted and therefore might be freed
prematurely, which can result in various WARNINGs. For example:
$ ip link add name br0 type bridge vlan_filtering 1
$ teamd -t team0 -d -c '{"runner": {"name": "lacp"}}'
$ ip link set dev team0 master br0
$ ip link set dev enp1s0np1 master team0
$ ip address add 192.0.2.1/24 dev enp1s0np1
The enslavement to team0 will fail because team0 already has an upper
and thus vlan_vids_del_by_dev() will be executed as part of team's error
path which will delete VID 1 from enp1s0np1 (added by br0 as PVID). The
WARNING will be generated when the driver will realize it can't find VID
1 on the port and bind it to a RIF.
Fix this by adding a reference count to the VLAN entries on the port, in
a similar fashion to the reference counting used by the corresponding
'vlan_vid_info' structure in the 8021q driver.

When multicast snooping is enabled, the Linux bridge resorts to flooding
unregistered multicast packets to all ports only in case it did not
detect a querier in the network.
The above condition is not reflected to underlying drivers, which is
especially problematic in IPv6 environments, as multicast snooping is
enabled by default and since neighbour solicitation packets might be
treated as unregistered multicast packets in case there is no
corresponding MDB entry.
Until the Linux bridge reflects its querier state to underlying drivers,
simply treat unregistered multicast packets as broadcast and allow them
to reach their destination.

This changeset moves ipvlan address under RCU protection, using
a per ipvlan device spinlock to protect list mutation and RCU
read access to protect list traversal.
Also explicitly use RCU read lock to traverse the per port
ipvlans list, so that we can now perform a full address lookup
without asserting the RTNL lock.
Overall this allows the ipvlan driver to check fully for duplicate
addresses - before this commit ipv6 addresses assigned by autoconf
via prefix delegation where accepted without any check - and avoid
the following rntl assertion failure still in the same code path:

When the parent changes its configuration, the child might need to clean

Add the option to set a qdisc per tclass. Match the qdisc to the tclass by
parent ID. Supported currently for sch_red only.
It allows offloading sch_prio as root qdisc and sch_red as its child.
(However, doing so might corrupt the stats for both parent and child.)

Marvell PPv2 controller allows for generic packet filtering. This commit
adds entries to implement VLAN filtering. The approach taken is :
- Filter entries that would match on the presence of the VLAN tag
(existing VLAN detection, DSA / EDSA detection) will set the next
lookup ID to be for the VID.
- For each VLAN existing on a given port, we add an entry that matches
this specific VID. If the incoming packet matches the VID entry, it is
set for the next lookup in the chain (LU_L2).
- A Guard entry is added for each port, that will match if the incoming
packet didn't match any of the above VID entries. This entry tags the
packet to be dropped.
Due to this design, and the fact that the total 256 filter entries are
also used for other purposes, we have a limit of 10 VLANs per port. To
accommodate the case where we would need more VLANS on one port, this
patch implements the ndo_set_features to allow for disabling of VLAN
filtering using ethtool.
The default config has VLAN filtering disabled.

The MACH_IS_MAC test is redundant here because the platform device
won't get registered unless MACH_IS_MAC.
Adopt module_platform_driver() convention.

Don't log the unexpanded "eth%d" format string.
Log the chip revision in the probe message (consistent with mace.c).
Drop redundant debug messages for FIFO events recorded in the
interface statistics (also consistent with mace.c).
