This patch adds a change sequence counter to each net namespace
which is bumped whenever a netdevice is added or removed from
the list. If such a change occurred while a link dump took place,
the dump will have the NLM_F_DUMP_INTR flag set in the first
message which has been interrupted and in all subsequent messages
of the same dump.

Note that links may still be modified or renamed while a dump is
taking place but we can guarantee for userspace to receive a
complete list of links and not miss any.

Testing:
I have added 500 VLAN netdevices to make sure the dump is split
over multiple messages. Then while continuously dumping links in
one process I also continuously deleted and re-added a dummy
netdevice in another process. Multiple dumps per seconds have
had the NLM_F_DUMP_INTR flag set.

I guess we can wait for Johannes patch to hit net-next via the
wireless tree.  I just wanted to give this some testing right away.

On some skews, the BE card sends pause frames (and not drop pkts) if there are
no more posted buffers available for packet reception.  This behaviour has a
side effect: When an interface is disabled, buffers are no longer posted on the
corresponding RX rings. All broadcast and multicast traffic being received on
the port will quickly fill up the PMEM and cause pause push back. As the PMEM
is shared by both the ports, all traffic being received on the other (enabled)
port also gets stalled.
The fix is to destroy RX rings when the interface is disabled. If there is no
RX ring match in the RXF lookup, the packets are discarded and so don't hog the
PMEM.
The RXQ creation cmd must now use MCC instead of MBOX as they are are called
post MCC queue creation.

External loopback test can be performed by application without any driver
support on normal Ethernet cards.
But on CNA devices, where multiple functions share same physical port.
Here internal loopback test and external loopback test can be initiated by
multiple functions at same time. To co exist all functions, firmware need
to regulate what test can be run by which function. So before performing external
loopback test, command need to send to firmware, which will quiescent other functions.

User may not want to run external loopback test always. As special cable need to be
connected for this test.
So adding explicit flag in ethtool self test, which will specify interface
to perform external loopback test.

enic driver and the underlying hardware use different units for representing the interrupt coalesce timer.
Driver converts the interrupt coalesce timer in usec to hardware cycles while setting the relevant hardware
registers. The conversion factor can be different for each of the adapter hardware types. So it is dynamically
learnt from the adapter firmware using the devcmd CMD_INTR_COAL_CONVERT. This allows the driver to configure
the hardware interrupt coalesce timers in a platform independent way.

When receiving packets from another guest on the same hypervisor, it's
generally possible to receive large packets because no segmentation is
necessary and these packets are handled by LRO.  However, when doing
routing or bridging we must disable LRO and lose this benefit.  In
these cases GRO can still be used and it is very effective because the
packets which are segmented in the hypervisor are received very close
together and can easily be merged.
