commit fba875591 ("disable TX in be_close()") disabled TX in be_close()
to protect be_xmit() from touching freed up queues in the AER recovery
flow. But, TX must be disabled *before* cleaning up TX completions in
the close() path, not after. This allows be_tx_compl_clean() to free up
all TX-req skbs that were notified to the HW.

Regarding the iwlwifi bits, Johannes says:
"We revert an rfkill bugfix that unfortunately caused more bugs, shuffle
some code to avoid touching the PCIe device before it's enabled and
disconnect if firmware fails to do our bidding. I also have Stanislaw's
fix to not crash in some channel switch scenarios."
As for the mac80211 bits, Johannes says:
"This time, I have one fix from Dan Carpenter for users of
nl80211hdr_put(), and one fix from myself fixing a regression with the
libertas driver."
Along with the above...
Dan Carpenter fixes some incorrectly placed "address of" operators
in hostap that caused copying of junk data.
Jussi Kivilinna corrects zd1201 to use an allocated buffer rather

There are possible HW configurations in which PFs will have SR-IOV capability
but will have Max VFs set to 0 - this happens when there are Multi-Function
devices where the VFs are allocated to only some of the PFs.
DMAE is configured to support VFs only if the configuring PF has supported VFs.
In case the first PF to be loaded will be one without supported VFs, it will
not configure DMAE to the VF-supporting mode. When VFs of other PFs will be
loaded later on, they will not be able to communicate with their PF.
This changes the requirement for configuring DMAE for VF-supporting mode;
If the device has SR-IOV capabilities there must be some PF that has
max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

vxlan: add necessary locking on device removal
The problem is that vxlan_dellink(), which is called with RTNL lock
held, tries to flush the workqueue synchronously, but apparently
igmp_join and igmp_leave work need to hold RTNL lock too, therefore we
have a soft lockup!
As suggested by Stephen, probably the flush_workqueue can just be
removed and let the normal refcounting work. The workqueue has a
reference to device and socket, therefore the cleanups should work
correctly.
