Shlomo Pongratz ad3f428e0f [SCSI] be2iscsi: Fix possible reentrancy issue in be_iopoll
The driver creates "NAPI" context per core which is fine,
however the above routine declares the ret variable as static!
Thus there is only one instance of this variable!
When this routine is called from more than one thread of execution,
than the result is unpredictable.

         static unsigned int ret;
         .....

         ret = beiscsi_process_cq(pbe_eq);
                 <--------Another thread can enter here and change "ret".
         if (ret < budget) {

         }
                 <--------Another thread can enter here and change "ret".
         return ret;

Fix - remove the "static"

protocols as well as by the FCoE encapsulation for Fibre Channel payloads on
the established virtual link. One of the goals of FC-BB-5 was to be as
nonintrusive as possible on initiators and targets, and therefore FIP VLAN
discovery occurs in the native VLAN used by the initiator or target to
exchange Ethernet traffic. The FIP VLAN discovery protocol is the only FIP
protocol running on the native VLAN; all other FIP protocols run on the
discovered FCoE VLANs.

If an administrator has manually configured FCoE VLANs on ENodes and FCFs,
there is no need to use this protocol. FIP and FCoE will run over the
configured VLANs.

An ENode without FCoE VLANs configuration would use this automated discovery
protocol to discover over which VLANs FCoE is running.

The ENode sends a FIP VLAN discovery request to a multicast MAC address called
All-FCF-MACs, which is a multicast MAC address to which all FCFs listen.

All FCFs that can be reached in the native VLAN of the ENode are expected to
respond on the same VLAN with a response that lists one or more FCoE VLANs
that are available for the ENode's VN_Port login. This protocol has the sole
purpose of allowing the ENode to discover all the available FCoE VLANs.

Now the ENode may enable a subset of these VLANs for FCoE Running the FIP
protocol in these VLANs on a per VLAN basis. And FCoE data transactions also
would occur on this VLAN. Hence, Except for FIP VLAN discovery, all other FIP
and FCoE traffic runs on the selected FCoE VLAN.  Its only the FIP VLAN
Discovery protocol that is permitted to run on the Default native VLAN of the
system.

[**** NOTE ****]
We are working on moving this feature definitions and functionality to libfcoe
module. We need this patch to be approved, as Suse is looking forward to merge
this feature in SLES 11 SP3 release.  Once this patch is approved, we will
submit patch which should move vlan discovery feature to libfoce.

Pull networking updates from David Miller:
 "Highlights (1721 non-merge commits, this has to be a record of some
  sort):

   1) Add 'random' mode to team driver, from Jiri Pirko and Eric
      Dumazet.

   2) Make it so that any driver that supports configuration of multiple
      MAC addresses can provide the forwarding database add and del
      calls by providing a default implementation and hooking that up if
      the driver doesn't have an explicit set of handlers.  From Vlad
      Yasevich.

   3) Support GSO segmentation over tunnels and other encapsulating
      devices such as VXLAN, from Pravin B Shelar.

   4) Support L2 GRE tunnels in the flow dissector, from Michael Dalton.

   5) Implement Tail Loss Probe (TLP) detection in TCP, from Nandita
      Dukkipati.

   6) In the PHY layer, allow supporting wake-on-lan in situations where
      the PHY registers have to be written for it to be configured.

      Use it to support wake-on-lan in mv643xx_eth.

      From Michael Stapelberg.

   7) Significantly improve firewire IPV6 support, from YOSHIFUJI
      Hideaki.

   8) Allow multiple packets to be sent in a single transmission using
      network coding in batman-adv, from Martin Hundebøll.

   9) Add support for T5 cxgb4 chips, from Santosh Rastapur.

  10) Generalize the VXLAN forwarding tables so that there is more
      flexibility in configurating various aspects of the endpoints.
      From David Stevens.

  11) Support RSS and TSO in hardware over GRE tunnels in bxn2x driver,
      from Dmitry Kravkov.

  12) Zero copy support in nfnelink_queue, from Eric Dumazet and Pablo
      Neira Ayuso.

  13) Start adding networking selftests.

  14) In situations of overload on the same AF_PACKET fanout socket, or
      per-cpu packet receive queue, minimize drop by distributing the
      load to other cpus/fanouts.  From Willem de Bruijn and Eric
      Dumazet.

  15) Add support for new payload offset BPF instruction, from Daniel
      Borkmann.

  16) Convert several drivers over to mdoule_platform_driver(), from
      Sachin Kamat.

  17) Provide a minimal BPF JIT image disassembler userspace tool, from
      Daniel Borkmann.

  18) Rewrite F-RTO implementation in TCP to match the final
      specification of it in RFC4138 and RFC5682.  From Yuchung Cheng.

  19) Provide netlink socket diag of netlink sockets ("Yo dawg, I hear
      you like netlink, so I implemented netlink dumping of netlink
      sockets.") From Andrey Vagin.

  20) Remove ugly passing of rtnetlink attributes into rtnl_doit
      functions, from Thomas Graf.

      from Jesper Dangaard Brouer.

  25) Get rid of using non-type-safe NLMSG_* macros and use nlmsg_*()
