The PF was not correctly registering any of its VLANs.  As a result any
VLAN tagged traffic from the VF would not be delivered to the PF because
the VLAN was never assigned to the PF pool.

In addition the VF was not allowed to receive traffic from VLAN 0 if it was
allowed to receive untagged frames.  This change corrects that so that it
will correctly receive traffic from VLAN 0.

The scsi netlink code confuses the netlink port id with a process id,
going so far as to read NETLINK_CREDS(skb)->pid instead of the correct
NETLINK_CB(skb).pid.  Fortunately it does not matter because nothing
registers to respond to scsi netlink requests.

The only interesting use of the scsi_netlink interface is
fc_host_post_vendor_event which sends a netlink multicast message.

Since nothing registers to handle scsi netlink messages kill all of the
registration logic, while retaining the same error handling behavior
preserving the userspace visible behavior and removing all of the
confused code that thought a netlink port id was a process id.

This was tested with a kernel allyesconfig build which had no problems.

Various flows in the bnx2x driver cause a link-flap - if the link
is up, it would be toggled down (after a mac/phy reset) and then
taken back up.

In many of these cases, there is no need to do cause such a flap,
as the associated flows should not actually affect the link.

This patch adds the 'Link Flap Avoidance' mechanism, which allows
the driver to better determine if a given flow requires a link change,
and thus minimize the number of link flaps caused by the driver.

====================
The following patchset contains four Netfilter updates, mostly targeting
to fix issues added with IPv6 NAT, and one little IPVS update for net-next:

* Remove unneeded conditional free of skb in nfnetlink_queue, from
  Wei Yongjun.

* One semantic path from coccinelle detected the use of list_del +
  INIT_LIST_HEAD, instead of list_del_init, again from Wei Yongjun.

* Fix out-of-bound memory access in the NAT address selection, from
  Florian Westphal. This was introduced with the IPv6 NAT patches.

* Two fixes for crashes that were introduced in the recently merged
  IPv6 NAT support, from myself.

When a policy expiration is triggered from user space the request
travels through km_policy_expired and ultimately into
xfrm_exp_policy_notify which calls build_polexpire.  build_polexpire
uses the netlink port passed to km_policy_expired as the source port for
the netlink message it builds.

When a state expiration is triggered from user space the request travles
through km_state_expired and ultimately into xfrm_exp_state_notify which
calls build_expire.  build_expire uses the netlink port passed to
km_state_expired as the source port for the netlink message it builds.

Pass nlh->nlmsg_pid from the user generated netlink message that
requested the expiration to km_policy_expired and km_state_expired
instead of current->pid which is not a netlink port number.

QMI requests exceeding 1500 bytes are possible and
device firmware does not handle fragmented messages
very well.  It is therefore necessary to increase
the maximum message size from the current 512 bytes.

The protocol message size limit is not documented
in any publicly known source, but the out of tree
driver from CodeAurora use 4 kB.  This is therefore
chosen as the new arbitrary default until the real
limit is known.

This should allow any QMI message to be transmitted
without fragmentation, fixing known issues with GPS
