We special case port == 0 to mean all ports, and it's the default,
so if a user passes in 0, they likely meant 1 instead. Throw an
error because they probably didn't mean to specify the default
behavior of scan all ports. Path of least surprise and all that.

that know it is being done, but it can also lead to hard to
diagnose problems if you add a new application into the mix
and it is unaware of this hammer being used and unable to
handle the situation.

That table only tells the NIC to listen to specific multicast

the SM to subscribe the port to the multicast groups it needs
subscribed too. In both cases
won't know to look there when working
specifically on an extension.

This patch resolves Red Hat bugzilla #1072645.
The above referenced commit was added during the 3.11 release cycle, so
this fix is suitable for any stable kernels from that point on.

The ib_srpt module has a metric ton of printks for debugging and
warnings and such. And it never prefaces a single one of them with
information to allow an admin to know what errant module is spewing
garbage all through their dmesg output. Fix that.

GID change events need a refresh just like LID change events and several
others. Handle this the same as the others.

As mcast_leave calls ib_sa_multicast_leave, and as member in
core/multicast.c is ref counted, we run into an unbalanced refcount
issue. To avoid stomping on each others removes, take the rtnl lock
specifically when we are deleting the entries from the remove list.

Various places in the IPoIB code had a deadlock related to flushing the
ipoib workqueue. Now that we have per device workqueues and a specific
flush workqueue, there is no longer a deadlock issue with flushing the
device specific workqueues and we can do so unilaterally.

always flush the device specific work queues without having deadlock

In this way, mcast_dev_flush always sees consistent state in regards to
mcast-mc membership at the time that the wait_for_completion() returns.

taken the fact that it is queued on a
single thread workqueue with all of the ipoib_mcast_join_task's and
therefore has no need to stop the join task while it runs, we can do
away with the flush parameter and unilaterally flush always.

mlx4_ib0
up is in fact racing with both ups and downs of mlx4_ib0.8002. The same
is true for the mlx4_ib1 interface and its child. With my patch set in
place, these loops are currently running without a problem and have passed
15,000 up/down cycles per interface.

Setting the mtu can safely be moved to the carrier_on_task, which keeps
us from needing to take the rtnl lock in the join_finish section.
