Bluetooth: Support static address when BR/EDR has been disabled
Every BR/EDR/LE dual-mode controller requires to have a public address
and so far that has become the identity address and own address. The
only way to change that behavior was with a force_static_address
debugfs option.
However the host can actually disable the BR/EDR part of a dual-mode
controller and turn into a single mode LE controller. In that case
it makes perfect sense for a host to use a chosen static address
instead of the public address.
So if the host disables BR/EDR and configures a static address, then
that static address is used as identity address and own address. If
the host does not configure a static address, then the public address
is used as before.

xen-netback: support frontends without feature-rx-notify again
Commit
bc96f648df1bbc2729abbb84513cf4f64273a1f1 (xen-netback: make
feature-rx-notify mandatory) incorrectly assumed that there were no
frontends in use that did not support this feature. But the frontend
driver in MiniOS does not and since this is used by (qemu) stubdoms,
these stopped working.
Netback sort of works as-is in this mode except:
- If there are no Rx requests and the internal Rx queue fills, only
the drain timeout will wake the thread. The default drain timeout
of 10 s would give unacceptable pauses.
- If an Rx stall was detected and the internal Rx queue is drained,
then the Rx thread would never wake.
Handle these two cases (when feature-rx-notify is disabled) by:
- Reducing the drain timeout to 30 ms.
- Disabling Rx stall detection.

geneve: Fix races between socket add and release.
Currently, searching for a socket to add a reference to is not
synchronized with deletion of sockets. This can result in use
after free if there is another operation that is removing a
socket at the same time. Solving this requires both holding the
appropriate lock and checking the refcount to ensure that it

Bluetooth: Fix bug with filter in service discovery optimization
The optimization for filtering out extended inquiry results, advertising
reports or scan response data based on provided UUID list has a logic
bug. In case no match is found in the advertising data, the scan
response is ignored and not checked against the filter. This will lead
to events being filtered wrongly.
Change the code to actually only drop the events when the scan response
data is not present. If it is present, it needs to be checked against
the provided filter.
The patch is a bit more complex than it needs to be. That is because
it also fixes this compiler warning that some gcc versions produce.

xen-netfront: use napi_complete() correctly to prevent Rx stalling
After
d75b1ade567ffab085e8adbbdacf0092d10cd09c (net: less interrupt
masking in NAPI) the napi instance is removed from the per-cpu list
prior to calling the n->poll(), and is only requeued if all of the
budget was used. This inadvertently broke netfront because netfront
does not use NAPI correctly.
If netfront had not used all of its budget it would do a final check
for any Rx responses and avoid calling napi_complete() if there were
more responses. It would still return under budget so it would never
be rescheduled. The final check would also not re-enable the Rx
interrupt.
Additionally, xenvif_poll() would also call napi_complete() /after/
enabling the interrupt. This resulted in a race between the
napi_complete() and the napi_schedule() in the interrupt handler. The
use of local_irq_save/restore() avoided by race iff the handler is
running on the same CPU but not if it was running on a different CPU.
Fix both of these by always calling napi_compete() if the budget was
not all used, and then calling napi_schedule() if the final checks
says there's more work.

Debug code prints the fifo name via custom dev_warn() wrappers. The
fifo_names array is only non-zero when debugging is manually enabled,
which is all well and good. However, it's *not* good that this array
uses zero-length arrays in the non-debug case, and so it doesn't
actually have any memory allocated to it. This means that as far as we
know, fifo_names[i] actually points to garbage memory.
I've seen this in my log:
[ 4601.205511] brcmsmac bcma0:1: wl0: brcms_c_d11hdrs_mac80211: �GeL txop exceeded phylen 137/256 dur 1602/1504
So let's give this array space enough to fill it with a NULL byte.

net/macb: fix multiqueue support patch up
This series of patches is a fixup for the multiqueue support patch.
The first patch fixes a bug introduced by the multiqueue support patch.
The second one doesn't fix a bug but simplify the source code by removing
useless calls to devm_free_irq() since we use managed device resources for
IRQs.
They were applied on the net-next tree and tested with a sama5d36ek board.

gre: fix the inner mac header in nbma tunnel xmit path
The NBMA GRE tunnels temporarily push GRE header that contain the
per-packet NBMA destination on the skb via header ops early in xmit
path. It is the later pulled before the real GRE header is constructed.
The inner mac was thus set differently in nbma case: the GRE header
has been pushed by neighbor layer, and mac header points to beginning
of the temporary gre header (set by dev_queue_xmit).
Now that the offloads expect mac header to point to the gre payload,
fix the xmit patch to:
- pull first the temporary gre header away
- and reset mac header to point to gre payload
This fixes tso to work again with nbma tunnels.
