2016-03-07rtlwifi: pass struct rtl_stats by reference as it is more efficientColin Ian King
passing rtl_stats by value is inefficient; the structure is over 300 bytes in size and generally just one field (packet_report_type) is being accessed, so the pass by value is a relatively large overhead. This change just affects just the rx_command_packet calls.

2016-03-07brcmfmac: increase timeout for tx eapolHante Meuleman
When keys get set and updated this has to happen after eapol got transmitted (without key or old key) before the key can be updated. To make sure the order of sending eapol and configuring key is done correctly a timeout for tx of eapol is applied. This timeout is set to 50 msec, which is not always enough. Especially in AP mode and key updates the timeout may need to be much longer because client(s) can be in powersave. Increase the timeout from 50 to 950 msec.

2016-03-03net: ezchip: adapt driver to little endian architectureLada Trimasova
Since ezchip network driver is written with big endian EZChip platform it is necessary to add support for little endian architecture. The first issue is that the order of the bits in a bit field is implementation specific. So all the bit fields are removed. Named constants are used to access necessary fields. And the second one is that network byte order is big endian. For example, data on ethernet is transmitted with most-significant octet (byte) first. So in case of little endian architecture it is important to swap data byte order when we read it from register. In case of unaligned access we can use "get_unaligned_be32" and in other case we can use function "ioread32_rep" which reads all data from register and works either with little endian or big endian architecture. And then when we are going to write data to register we need to restore byte order using the function "put_unaligned_be32" in case of unaligned access and in other case "iowrite32_rep". The last little fix is a space between type and pointer to observe coding style.

2016-03-03net: mellanox: add DEVLINK dependenciesArnd Bergmann
The new NET_DEVLINK infrastructure can be a loadable module, but the drivers using it might be built-in, which causes link errors like: drivers/net/built-in.o: In function `mlx4_load_one': :(.text+0x2fbfda): undefined reference to `devlink_port_register' :(.text+0x2fc084): undefined reference to `devlink_port_unregister' drivers/net/built-in.o: In function `mlxsw_sx_port_remove': :(.text+0x33a03a): undefined reference to `devlink_port_type_clear' :(.text+0x33a04e): undefined reference to `devlink_port_unregister' There are multiple ways to avoid this: a) add 'depends on NET_DEVLINK || !NET_DEVLINK' dependencies for each user b) use 'select NET_DEVLINK' from each driver that uses it and hide the symbol in Kconfig. c) make NET_DEVLINK a 'bool' option so we don't have to list it as a dependency, and rely on the APIs to be stubbed out when it is disabled d) use IS_REACHABLE() rather than IS_ENABLED() to check for NET_DEVLINK in include/net/devlink.h This implements a variation of approach a) by adding an intermediate symbol that drivers can depend on, and changes the three drivers using it.

The .valid flag is used later, so I'm replacing the array of structures with an array of bools. An obvious follow-up optimization would be to replace it with a bitmask and set_bit()/find_first_bit()/ find_last_bit()/... operations. However, I have not tested this patch, so I sticked to the simpler transformation that does the job of reducing the stack usage to a harmless level.

To enable per peer stats feature we are reducing the number of peers. Firmware has introduced tx stats feature. We have memory limitation in firmware to add these additional bytes. These are the new variables introduced in the firmware. ======== ======================= Variable Bytes required/per rate ======== ======================= TX success packets 1 TX failed packets 1 Retry packets 1 Success bytes 2 TX failed bytes 2 Retry bytes 2 Tx duration 4 Rate 1 Bw and AMPDU flags 1 Total 16 (because of allocation in word pattern) Firmware sends these tx_stats in pktlog. If we consider 4 feedbacks at a time, Frimware need about ~1K memory for coding and 8192 bytes required / per rate [ 4*16*128(peers)]. To accommodate this firmware needs to reduce 10 peers. This fixes a firmware crash with firmware-5.bin_10.2.4.70.22-2. Signed-off-by: Anilkumar Kolli <akolli@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-03-03ath10k: process htt rx indication as batch modeRajkumar Manoharan
On multicore systems, it is possible that txrx tasket can run in parallel with pci tasklet (i.e smp affinity of ath10k irq is assigned to multiple CPUs). Feeding and consuming from the same rx completion list leads to txrx tasklet runs for longer period. Prevent this by processing a snapshot of rx queue by moving list into temporary list. Consecutive received frames will be processed in next batch. Signed-off-by: Rajkumar Manoharan <rmanohar@qti.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>
2016-03-03ath10k: reduce rx_lock contention for htt rx indicationRajkumar Manoharan
Received frame indications are queued into a skb list and latest processed by txrx tasklet. This skb queue is protected by htt rx lock. Since the entire rx processing till delivering frame to mac80211 and replenish tasks are processed under rx_lock protection, there might be some delay in queuing newly received rx frame into that list on multicore systems. Optimize this by using skb list lock while accessing rx completion queue instead of htt rx lock.

2016-03-03ath10k: add hw_rev to trace events to support pktlogAshok Raj Nagarajan
pktlog data is different between firmware variants (eg. 10.2 vs 10.4). To have a unified user space script to decode pktlog trace events generated, it is desirable to know which firmware variant has provided the events and thereby decode the pktlogs appropriately. Hardware revision (hw_rev) helps to determine the firmware variant sending these trace events. So add hw_rev to trace events.

2016-03-03ath10k: fix pktlog in QCA99X0Ashok Raj Nagarajan
Currently, we are providing wrong payload data of pktlog to trace points. Data we receive from FW through copy engine 8 contains pktlog data alone. We don't need to parse anything in driver before handing it to trace points.

2016-03-03ath10k: fix pointless update of peer stats listMohammed Shafi Shajakhan
We periodically receive f/w stats event for updating the rx duration and there is no reason to keep on appending the f/w stats peer list, as this gets completely cleaned up when the user polls for f/w stats {pdev, vdev, peer stats}.
