qlcnic: SR-IOV and FW-dump enhancements

This patch series contain following enhancements.

* SR-IOV enhancements:
 - Allow SR-IOV VF's to probe in hypervisor. SR-IOV VF can be
   uplinked to bridge/macvtap device with this change.
 - Commands from VF are processed in process context
   as it may sleep during PF-VF communication. Earlier
   we use to process qlcnic_sriov_vf_set_multi function in
   process context but now we process individual commands.
 - As SR-IOV VF's can be uplinked to bridge/macvtap device
   support mac-learning to allow communication through
   embedded switch.

* FW-dump enhancement:
 - Support to collect RDMEM section of firmware dump using
   PEX DMA method for 82xx series adapter.

* Changes in v2:
 - Removed unnecessary cast from void pointer to something
   else and verified this issue in entire patch series as
   per David Miller's suggestion.

Please apply this series to net-next.

tipc: overhaul node action flags

We currently have two problems with the node flags field:
 - The naming of the individual action flags is unclear and confusing
 - The flags are often not cleared individually,  making it hard to follow
   where this happens.

So the series aims to solve above two problems.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Each node action flag should be set or cleared separately, instead
we now set the whole flags variable in one shot, and it's turned
out to be hard to see which other flags are affected. Therefore,
for instance, we explicitly clear TIPC_WAIT_OWN_LINKS_DOWN bit in
node_lost_contact().

net: Checksum offload changes - Part II

I am working on overhauling RX checksum offload. Goals of this effort
are:

- Specify what exactly it means when driver returns CHECKSUM_UNNECESSARY
- Preserve CHECKSUM_COMPLETE through encapsulation layers
- Don't do skb_checksum more than once per packet
- Unify GRO and non-GRO csum verification as much as possible
- Unify the checksum functions (checksum_init)
- Simply code

What is in this second patch set:

- Call common inet checksum validation functions in ICMP{4,6},
  GRE{4,6}, and IGMP.
- In UDP, verify checksum before handing off to encap_rcv.
- Remove custom UDP checksum validation code in L2TP.

Please review carefully and test if possible, mucking with basic
checksum functions is always a little precarious :-)
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Validating the UDP checksum is now done in UDP before handing
packets to the encapsulation layer. Note that this also eliminates
the "feature" where L2TP can ignore a non-zero UDP checksum (doing
this was contrary to RFC 1122).

Commit 1f0f467b "qlcnic: Add hwmon interface to export board

when the hwmon framework is built as a module and the qlcnic
driver itself is built-in:

drivers/built-in.o: In function `qlcnic_register_hwmon_dev':
drivers/net/ethernet/qlogic/qlcnic/qlcnic_sysfs.c:1301:

commit 8f0ea0fe (snmp: reduce percpu needs by 50%)
reduced snmp array size to 1, so technically it doesn't have to be
an array any more. What's more, after the following commit:

	commit 933393f5
	Date:   Thu Dec 22 11:58:51 2011 -0600

	    percpu: Remove irqsafe_cpu_xxx variants

	    We simply say that regular this_cpu use must be safe regardless of
	    preemption and interrupt state.  That has no material change for x86
	    and s390 implementations of this_cpu operations.  However, arches that
	    do not provide their own implementation for this_cpu operations will
	    now get code generated that disables interrupts instead of preemption.

probably no arch wants to have SNMP_ARRAY_SZ == 2. At least after
almost 3 years, no one complains.

So, just convert the array to a single pointer and remove snmp_mib_init()
and snmp_mib_free() as well.

tipc: purge signal handler infrastructure

When we delay some actions to be executed in asynchronous contexts,
these usually add unnecessary code complexities, and make their
behaviours unpredictable and indeterministic. Moreover, as the signal
handler infrastructure is first stopped when tipc module is removed,
this may cause some potential risks for us. For instance, although
signal handler is already stopped, some tipc components still submit
signal requests to signal handler infrastructure, which may lead to
some resources not to be released or freed correctly.

So the series aims to convert all actions being performed in tasklet
context asynchronously with interface provided by signal handler
infrastructure to be executed synchronously, thereby deleting the
whole infrastructure of signal handler.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

In the previous commits of this series, we removed all asynchronous
actions which were based on the tasklet handler - "tipc_k_signal()".

So the moment has now come when we can completely remove the tasklet
handler infrastructure. That is done with this commit.
