scsi_netlink: Remove dead and buggy code

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.

bnx2x: Utilize Link Flap Avoidance

Change various flows in the bnx2x driver which up until now flapped

bnx2x: Link Flap Avoidance

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.

Merge branch 'master' of git://1984.lsi.us.es/nf-next

Pablo Neira Ayuso says:

====================
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.

libertas: set mac control synchronously during init

CMD_MAC_CONTROL is currently sent async to the firmware, and is sent
from the lbs_setup_firmware() path during device init.

This means that device init can complete with commands pending, and
the if_sdio driver will sometimes power down the device (after init)
with this command still pending.

This was causing an occasional spurious command timeout after init,
leading to a device reset.

mwifiex: update adapter->bss_prio_tbl[j].bss_prio_cur correctly

"adapter->bss_prio_tbl[j].bss_prio_head" points to linked list of
interfaces with priority 'j'. "bss_prio_tbl[j].bss_prio_cur" is
supposed to point to next interface every time the routine for
dequeuing the packet is called. This ensures that each interface
gets fair chance.

Currently we have AP and station interfaces with priority '0'.
Therefore "adapter->bss_prio_tbl[0].bss_prio_cur" should
alternately point to AP and station nodes. Since "bss_prio_cur"
is not correctly updated, for each packet picked for AP, two
packets are picked for station interface.

mwifiex: store mwifiex_ds_misc_subsc_evt in mwifiex_private

Since mwifiex_ds_misc_subsc_evt is used in an asynchronous case,
store the structure in the long-lived mwifiex_private instead of
on the calling stack.

This fixes a problem where the response of the asynchronous
operation would corrupt a stack frame potentially in use by
a different thread.
