aea48157ce staging: rtl8712: memory corruption in wpa_set_encryption()
->KeyMaterial is declared as a 16 byte array, but we only ever allocate
either 5 or 13 bytes of it.  The problem is that we memset() all 16
bytes to zero so we're memsetting past the end of the allocated memory.

I fixed this in slightly lazy way, by just allocating 16 bytes.  This
works but there is a lot more cleanup you could do to this code if you
wanted.  Which is why this code is in staging.

39e9526cec staging: rtl8712: Improve suspend/resume functionality.
Cancel pending URBs during suspend operation to avoid receiving ESHUTDOWN
in read/write completion callbacks while the device is suspended.

Receiving ESHUTDOWN in read/write completion callbacks will cause the
driver to enter a non-functioning "stopped" state from which the driver is
unable to recover without reloading the module.

485b099ad8 staging: rtl8723au: change parameter type in rtl8723a_set_rssi_cmd declaration
Previosly the function had the following prototype:
int rtl8723a_set_rssi_cmd(struct rtw_adapter *padapter, u8 *param)

My suggestion here is to modify the prototype this way:
int rtl8723a_set_rssi_cmd(struct rtw_adapter *padapter, u32 param)

We can do this based on the following considerations:
1. rtl8723a_set_rssi_cmd is used only with 32-bit "param" values
2. There's no point in using "u8 *param" until we pass param length
3. As we just read "param", it's ok to pass it by value

7c0b6bce6e staging: octeon: Fix logic for waking octeon ethernet tx queue.
Only wake tx queue when driver queue is back within bounds.

The logic here was just reenabling the queue when any buffers had been
freed.  the queue was stopped whenever the length exceeded 1000
(MAX_OUT_QUEUE_DEPTH), but then was essentially immediately started again.
On a congested link, the queue length would just keep increasing up to
around 8000 (for average size packets), at which point the hardware would
start refusing the packets and they would begin to be dropped.
This prevented the qdisc layer from effectively managing and prioritising
packets, as essentially all packets were being allowed into the driver
queue and then were being dropped by the hardware.

This change only restarts the queue if the length is less than 1000
(MAX_OUT_QUEUE_DEPTH).

5a89a875c9 staging: octeon-ethernet: fix TCP/UDP checksum calc
If the network portion of a frame is preceded by more than 14 bytes of
data, the checksum calculated in the HW is done over the wrong data and
is put in the wrong place.
In our use case an Octeon ethernet controller is connected to a Broadcom
switch chip. Extra data is included in the frame prior to egressing the
Octeon ethernet (i.e. 4 bytes of an 802.1Q tag, 4 bytes of a proprietary
BCM tag later stripped by the switch chip). This extra data causes the
checksum calculation to be incorrect.
The fix in this patch is to make use of the network header offset of the
skb. This enables the checksum to be calculated correctly.
This has been tested in both the configuration with the switch chip in
the egress path (as described above) and in a simple connection direct
to the wire.

All the IRQs for DPAA2 objects in the same DPRC must use
the ICID of that DPRC, as their device Id in the GIC-ITS.
Thus, all these IRQs must share the same ITT table in the GIC.
As a result, a pool of IRQs with the same device Id must be
preallocated per DPRC (fsl-mc bus instance). So, the fsl-mc
bus object allocator is extended to also provide services
to allocate IRQs to DPAA2 devices, from their parent fsl-mc bus
IRQ pool.
