1f27e2516c netfilter: xt_hashlimit: use _ALL macro to reject unknown flag bits
David Miller says:
     The canonical way to validate if the set bits are in a valid
     range is to have a "_ALL" macro, and test:
     if (val & ~XT_HASHLIMIT_ALL)
         goto err;"

make it so.

6d8823db42 qeth: recognize vlan devices in layer3 mode
The qeth layer3 driver is notified about IP address changes.
Changes concerning qeth driven network interfaces have to be
forwarded to the OSA-card. This includes IP addresses of VLAN
interfaces with a qeth device as base device. Function
qeth_l3_verify_vlan_dev() determines if the net_device of the
IP event belongs to a vlan device belonging to a qeth device
as real device. This function is broken starting with commit
7ff0bcf676 , which means IP
addresses of VLAN devices are no longer set at the base qeth
device. The patch repairs function qeth_l3_verify_vlan_dev().

865ec5523d fq_codel: should use qdisc backlog as threshold
codel_should_drop() logic allows a packet being not dropped if queue
size is under max packet size.

In fq_codel, we have two possible backlogs : The qdisc global one, and
the flow local one.

The meaningful one for codel_should_drop() should be the global backlog,
not the per flow one, so that thin flows can have a non zero drop/mark
probability.

0afd7ad9de mac802154: basic ieee802.15.4 device structures
The IEEE 802.15.4 Working Group focuses on the standardization of the
bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC.
The MAC layer provides access control to a shared channel and reliable
data delivery. The main functions performed by the MAC sublayer are:
association and disassociation, security control, optional star
network topology functions, such as beacon generation and Guaranteed
Time Slots (GTSs) management, generation of ACK frames (if used), and,
finally, application support for the two possible network topologies
described in the standard.

This is an initial commit which describes main data structures needed
for ieee802.15.4 compatible devices representation in the MAC layer.

b8924951f6 net/mlx4_core: Fix potential kernel Oops in res tracker during Dom0 driver unload
Currently the slave and master resources are deleted after master freed
all bitmaps. If any resources were not properly cleaned up during the
shutdown process, an Oops would result.

Fix so that delete slave (only) resources during cleanup. Master resources
are cleaned up during unload process, and need not separately be cleaned.

Note that during cleanup, we need to split the resource-tracker freeing
functionality.

Before removing all the bitmaps, we free any leftover slave resources.
However, we can only remove the resource tracker linked list after
all bitmap frees, since some of the freeing functions (e.g.,
mlx4_cleanup_eq_table) use paravirtualized FW commands which expect
the resource tracker linked list to be present.

681372a7a3 net/mlx4_core: Do not reset module-parameter num_vfs when fail to enable sriov
Consider the following scenario: 2 HCAs, where only one of which can run SRIOV.

If we reset the module parameter, all the VFs of the SRIOV HCA will be
claimed by the PPF host (-- the code relies on num_vfs being non-zero
to avoid this claiming, and num_vfs was reset when pci_enable_sriov failed
for the non-SRIOV HCA).

The solution is not to touch the num_vfs parameter.

Also, eliminate the unneeded check of num_vfs when disabling sriov
(the dev flag bit is sufficient).

8bac9ede68 net/mlx4_core: Fix init_port mask state for slaves
In function mlx4_INIT_PORT_wrapper, the port state mask for the
slave is only set if we are invoking the INIT_PORT fw command.

However, the reference count for the (initialized) port is
incremented anyway.

This creates a problem in that when we have multiple slaves,
then the CLOSE_PORT command will never be invoked. The
reason is that in the CLOSE_PORT wrapper, if the port-state
mask is zero for the slave (which it is), the wrapper returns
without doing anything. The only slave which will not return
immediately in the CLOSE_PORT wrapper is that slave for which
INIT_PORT was invoked.

The fix is to not have the port-state mask setting depend
on the logic for calling the INIT_PORT fw command.

3a3bfb61e6 net: Add net_ratelimited_function and net_<level>_ratelimited macros
__ratelimit() can be considered an inverted bool test because
it returns true when not ratelimited.  Several tests in the
kernel tree use this __ratelimit() function incorrectly.

No net_ratelimit uses are incorrect currently though.

Most uses of net_ratelimit are to log something via printk or
pr_<level>.

In order to minimize the uses of net_ratelimit, and to start
standardizing the code style used for __ratelimit() and net_ratelimit(),
add a net_ratelimited_function() macro and net_<level>_ratelimited()
logging macros similar to pr_<level>_ratelimited that use the global
net_ratelimit instead of a static per call site "struct ratelimit_state".
