Yevgeny Petrilin 38aab07c14 mlx4_en: Fix partial rings feature
In case of allocation failure, the actual ring size is rounded down to
nearest power of 2. The remaining descriptors are freed.
The CQ and SRQ are allocated with the actual size and the mask is updated.

Mohamed Abbas 40cefda9ce iwlcore: Add support for periodic RX interrupt
Periodic RX interrupt needed with ICT interrupt to prevent RX race.
Sending RX interrupt require many steps to be done in the
the device:
 1- write interrupt to current index in ICT table.
 2- dma RX frame.
 3- update RX shared data to indicate last write index.
 4- send interrupt.
This could lead to RX race, driver could receive RX interrupt
but the shared data changes does not reflect that.
this could lead to RX race, RX periodic will solve this race

Bing Zhao 2c7e57981f libertas: read SD8688 firmware status from new register
The scratch pad register is used to store firmware status after
firmware is downloaded and initialized. After firmware status is
verified OK, the same register is used to store RX packet length.
Hence the firmware status code is no longer valid afterwards.

SD8688 firmware introduces a new register for firmware status
which will never be overwritten.

Also add scratch_reg variable to if_sdio_card structure and
initialize it based on the model of the card during probe.

Jouni Malinen ccdfeab653 ath9k: Update Beacon timers based on timestamp from the AP
Some APs seem to drift away from the expected TBTT (timestamp %
beacon_int_in_usec differs quite a bit from zero) which can result in
us waking up way too early to receive a Beacon frame. In order to work
around this, re-configure the Beacon timers after having received a
Beacon frame from the AP (i.e., when we know the offset between the
expected TBTT and the actual time the AP is sending out the Beacon
frame).

Jouni Malinen 267a901274 ath9k: Optimize TBTT/DTIM calculation for timers
The previous version used a simple loop to go through all Beacon
frames when determining the next TBTT and DTIM count. This is not too
bad for the case where the setup happens before timesync (i.e., very
small TSF), but this can become very heavy operation if a short Beacon
interval is used and the current TSF is large.

In preparation for a patch to update timer setup based on Beacon
timestamp, optimize this routine to take fixed time regardless of the
actual TSF value.

Alternatively, SD8688 firmware offers an enhanced method for driver

IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready.
IF_SDIO_RX_LEN  0x42 is read every time when rx interrupt is received.

Inaky Perez-Gonzalez e069c0cf7c wimax/i2400m: usb: fix device reset on autosuspend while not yet idle
When the i2400m is connected to a network, the host interface (USB)
cannot be suspended. For that to happen, the device has to have
negotiated with the basestation to put the link on IDLE state.

If the host tries to put the device in standby while it is connected
but not idle, the device resets, as the driver should not do that.

To avoid triggering that, when the USB susbsytem requires the driver
to autosuspend the device, the driver checks if the device is not yet
idle. If it is not, the request is rejected (will be retried again
later on after the autosuspend timeout). At some point the device will
enter idle and the request will succeed (unless of course, there is
network traffic, but at that point, there is no idle neither in the
link or the host interface).

Patch to add the ability to detect drops in hardware interfaces via dropwatch.
Adds a tracepoint to net_rx_action to signal everytime a napi instance is
polled.  The dropmon code then periodically checks to see if the rx_frames
counter has changed, and if so, adds a drop notification to the netlink
protocol, using the reserved all-0's vector to indicate the drop location was in
hardware, rather than somewhere in the code.

Dan Carpenter 0975ecba3b RxRPC: Error handling for rxrpc_alloc_connection()
rxrpc_alloc_connection() doesn't return an error code on failure, it just
returns NULL.  IS_ERR(NULL) is false.

Robert Olsson 3ed18d76d9 ipv4: Fix oops with FIB_TRIE
It seems we can fix this by disabling preemption while we re-balance the 
trie. This is with the CONFIG_CLASSIC_RCU. It's been stress-tested at high 
loads continuesly taking a full BGP table up/down via iproute -batch.

Note. fib_trie is not updated for CONFIG_PREEMPT_RCU

Eric W. Biederman d95ed9275e af_packet: Teach to listen for multiple unicast addresses.
The the PACKET_ADD_MEMBERSHIP and the PACKET_DROP_MEMBERSHIP setsockopt
calls for af_packet already has all of the infrastructure needed to subscribe
to multiple mac addresses.  All that is missing is a flag to say that
the address we want to listen on is a unicast address.

So introduce PACKET_MR_UNICAST and wire it up to dev_unicast_add and
dev_unicast_delete.

Additionally I noticed that errors from dev_mc_add were not propagated
from packet_dev_mc so fix that.

Stephen Hemminger ca0f31125c netns: simplify net_ns_init
The net_ns_init code can be simplified. No need to save error code
if it is only going to panic if it is set 4 lines later.
