This will also improve handling of ipv6 tcp socket request
backlog when syncookies are not enabled. When backlog
becomes very deep, last quarter of backlog is limited to
validated destinations. Previously only ipv4 implemented
this logic, but now ipv6 does too.
Now we are only one step away from enabling timewait
recycling for ipv6, and that step is simply filling in
the implementation of tcp_v6_get_peer() and
tcp_v6_tw_get_peer().

The only thing AF-specific about remembering the timestamp
for a time-wait TCP socket is getting the peer.
Abstract that behind a new timewait_sock_ops vector.
Support for real IPV6 sockets is not filled in yet, but
curiously this makes timewait recycling start to work
for v4-mapped ipv6 sockets.

Allocate qdisc memory according to NUMA properties of cpus included in
xps map.
To be effective, qdisc should be (re)setup after changes
of /sys/class/net/eth<n>/queues/tx-<n>/xps_cpus
I added a numa_node field in struct netdev_queue, containing NUMA node
if all cpus included in xps_cpus share same node, else -1.

NIC partitioning is another flavor of multi function - having few
PCI functions share the same physical port. Unlike the currently
supported mode of multi-function which depends on the switch
configuration and uses outer-VLAN, the NPAR mode is switch independent
and uses the MAC addresses to distribute incoming packets to the different
functions. This patch adds the specific HW setting of the NPAR mode
and some distinctions between switch dependent (SD) and
switch independent (SI) multi-function (MF) modes where the configuration
is not the same.

Then we can make a completely generic tcp_remember_stamp()
that uses ->get_peer() as a helper, minimizing the AF specific

operate using a "struct inet_peer_base *" pointer.

Device initialization of a qeth device contains a STARTLAN step.
This step may fail, if cable is not yet plugged in. The qeth device
stays in state HARDSETUP until cable is plugged in. This prevents
further preparational initialization steps of the qeth device and
its network interface. This patch makes sure initialization of qeth
device continues, even though cable is not yet plugged in.
Once carrier is available, qeth is notified, triggers a recovery
which results in a working network interface.
