Slave latency range has been changed in Core Spec. 4.2 by Erratum 5419

Before:
connSlaveLatency <= ((connSupervisionTimeout / connIntervalMax) - 1)
After:
connSlaveLatency <= ((connSupervisionTimeout / (connIntervalMax*2)) - 1)
This patch makes hci_check_conn_params() check the allowable slave

Also avoids reference to the conn structure so makes

of chan->unacked_frames > 0 && chan->state == BT_CONNECTED
is true and convert the while loop to a do while loop.
__l2cap_wait_ack() change the function prototype to

During execution of l2cap_sock_shutdown() which might
sleep, the sk and chan structures can be in an unlocked
condition which potentially allows the structures to be
freed by other running threads. Therefore, there is a
possibility of a malfunction or memory reuse after being
freed.
Keep the sk and chan structures alive during the
execution of l2cap_sock_shutdown() by using their
respective hold and put functions. This allows the structures
to be freeable at the end of l2cap_sock_shutdown().

This patch introduces suspend and resume callbacks to mac802154. When
doing suspend we calling the stop driver callback which should stop the
receiving of frames. A transceiver should go into low-power mode then.
Calling resume will call the start driver callback, which starts receiving
again and allow to transmit frames.
This was tested only with the fakelb driver and a qemu vm by doing the
following commands:
echo "devices" > /sys/power/pm_test
echo "freeze" > /sys/power/state

bnx2x: update FW, rebrand and more
This patch series does several things - it updates the bnx2x FW into
7.12.30 which both contains some small fixes as well as opening the door
for several new features for the device - mainly vxlan/geneve offloads
and vlan filtering offload.
It then adds a new Multi-function mode [BD] which requires this FW in
order to operate.
In addition, this finally rebrands the driver from a 'broadcom' driver
into a 'qlogic' driver [although it would still reside under Broadcom's
tree in the kernel].

This moves bnx2x into using 7.12.30 FW. Said firmware fixes the following:
- Packets from a VF with pvid configured which were sent with a
different vlan were transmitted instead of being discarded.
- FCoE traffic might not recover after a failue while there's traffic
to another function.
In addition, this FW opens the door for the driver to implement several
new features; Specifically, this enhances the device's support for
encapsulated packets and will allow vxlan/geneve offloads to be added in
the future, as well as vlan filtering offload.

The driver is written as if it can adapt to a low memory situation allocating
less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In
reality though the driver would malfunction in this case. Stop being overly
smart and just fail in such situation -- this is achieved by moving the memory
allocation from ravb_ring_format() to ravb_ring_init().
We leave dma_map_single() calls in place but make their failure non-fatal
by marking the corresponding RX descriptors with zero data size which should
prevent DMA to an invalid addresses.

contains sparse entries. This causes memory corruption with openvswitch
since it allocates flow_cache with a multiple of num_possible_nodes() and
assumes the node variable returned by for_each_node will index into
flow->stats[node].
Use nr_node_ids to allocate a maximal sparse array instead of
num_possible_nodes().
