Extend log message if packets are ignored to include the TCP state, ie.
replace:

by:

[ 3968.070196] nf_ct_tcp: invalid packet ignored in state ESTABLISHED IN= OUT= SRC=...

This information is useful to know in what state we were while ignoring the

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
7ff0bcf6 , 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().

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.

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.

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.

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).
